The local maxima of f(x, y) are (0, 0), (1, -1/7), and (-1, -1/7). The local minima of f(x, y) are (-1, 1), (1, 1), and (0, 1/7). The saddle points of f(x, y) are (0, 1/7) and (0, -1/7).

The local maxima of f(x, y) can be found by setting the first partial derivatives equal to zero and solving for x and y. The resulting equations are x = 0, y = 0, x = 1, y = -1/7, and x = -1, y = -1/7. Substituting these values into f(x, y) gives the values of f(x, y) at these points, which are all greater than the minimum value of f(x, y).

The local minima of f(x, y) can be found by setting the second partial derivatives equal to zero and checking the sign of the Hessian matrix. The resulting equations are x = -1, y = 1, x = 1, y = 1, and x = 0, y = 1/7. Substituting these values into f(x, y) gives the values of f(x, y) at these points, which are all less than the maximum value of f(x, y).

The saddle points of f(x, y) can be found by setting the Hessian matrix equal to zero and checking the sign of the determinant. The resulting equations are x = 0, y = 1/7 and x = 0, y = -1/7.

Answer: 9

Step-by-step explanation:

Answer:To find the average rate of change for the interval from x = 5 to x = 6, we need to calculate the change in the function values over that interval and divide it by the change in x.

Given the points (5, 0) and (6, 4), we can calculate the change in the function values:

Change in y = 4 - 0 = 4

Change in x = 6 - 5 = 1

Average rate of change = Change in y / Change in x = 4 / 1 = 4

Therefore, the correct answer is 4. None of the given options (A, B, C, or D) match the correct answer.

Step-by-step explanation:

Given that the set of vectors (a,3,7) is a linearly independent set of vectors in V.

Now, let's assume that the set of vectors {a+B, B+,y+a} is a linearly dependent set of vectors in V.

As the set of vectors {a+B, B+,y+a} is linearly dependent, we have;

α1(a + b) + α2(b + c) + α3(a + c) = 0

Where α1, α2, and α3 are not all zero.

Now, let's split it up and solve further;

α1a + α1b + α2b + α2c + α3a + α3c = 0

(α1 + α3)a + (α1 + α2)b + (α2 + α3)c = 0

Now, a linear combination of vectors in {a, b, c} is equal to zero.

As (a, 3, 7) is a linearly independent set, it implies that α1 + α3 = 0, α1 + α2 = 0, and α2 + α3 = 0.

Therefore, α1 = α2 = α3 = 0, contradicting our original statement that α1, α2, and α3 are not all zero.

As we have proved that the set of vectors {a+B, B+,y+a} is a linearly independent set of vectors in V, which completes the proof.

Hence the answer is {a+B, B+,y+a} is also a linearly independent set of vectors in V.

To make the function f(x) = e^(-1/x²) differentiable on (-∞, +∞), the value of a that satisfies this condition is a = 0.

In order for f(x) to be differentiable at x = 0, the left and right derivatives at that point must be equal. We calculate the left derivative by taking the limit as h approaches 0- of [f(0+h) - f(0)]/h. Substituting the given function, we obtain the left derivative as lim(h→0-) [e^(-1/h²) - 0]/h. Simplifying, we find that this limit equals 0.

Next, we calculate the right derivative by taking the limit as h approaches 0+ of [f(0+h) - f(0)]/h. Again, substituting the given function, we have lim(h→0+) [e^(-1/h²) - 0]/h. By simplifying and using the properties of exponential functions, we find that this limit also equals 0.

Since the left and right derivatives are both 0, we conclude that f(x) is differentiable at x = 0 if a = 0.

The curvature function, k(t), can be calculated using the formula k(t) = |x'(t)y''(t) - x''(t)y'(t)| / (x'(t)^2 + y'(t)^2)^(3/2).

For the given plane curve r(t) = (9sin(3t), 9sin(4t)), we need to find the first and second derivatives of x(t) and y(t). Taking the derivatives, we have x'(t) = 27cos(3t), y'(t) = 36cos(4t), x''(t) = -81sin(3t), and y''(t) = -144sin(4t).

Substituting these values into the curvature formula, we get k(t) = |27cos(3t)(-144sin(4t)) - (-81sin(3t)36cos(4t))| / ((27cos(3t))^2 + (36cos(4t))^2)^(3/2).

Simplifying further, k(t) = |3888sin(3t)sin(4t) + 2916sin(3t)sin(4t)| / ((729cos(3t))^2 + (1296cos(4t))^2)^(3/2).

Therefore, the orthogonal projection of v onto the subspace W is approximately (-32.27, -64.57, -103.89, -16.71).

To find the orthogonal projection of vector v onto the subspace W spanned by the given vectors, we can use the formula:

projₓy = (y⋅x / ||x||²) * x

where x represents the vectors spanning the subspace, y represents the vector we want to project, and ⋅ denotes the dot product.

Let's calculate the orthogonal projection:

Step 1: Normalize the spanning vectors.

First, we normalize the spanning vectors of W:

u₁ = (-1/√6, -2/√6, -3/√6, -2/√6)

u₂ = (4/√53, 5/√53, -26/√53)

Step 2: Calculate the dot product.

Next, we calculate the dot product of the vector we want to project, v, with the normalized spanning vectors:

v⋅u₁ = (-1)(-1/√6) + (-16)(-2/√6) + (-4)(-3/√6) + (12)(-2/√6)

= 1/√6 + 32/√6 + 12/√6 - 24/√6

= 21/√6

v⋅u₂ = (-1)(4/√53) + (-16)(5/√53) + (-4)(-26/√53) + (12)(0/√53)

= -4/√53 - 80/√53 + 104/√53 + 0

= 20/√53

Step 3: Calculate the projection.

Finally, we calculate the orthogonal projection of v onto the subspace W:

projW(v) = (v⋅u₁) * u₁ + (v⋅u₂) * u₂

= (21/√6) * (-1/√6, -2/√6, -3/√6, -2/√6) + (20/√53) * (4/√53, 5/√53, -26/√53)

= (-21/6, -42/6, -63/6, -42/6) + (80/53, 100/53, -520/53)

= (-21/6 + 80/53, -42/6 + 100/53, -63/6 - 520/53, -42/6)

= (-10284/318, -20544/318, -33036/318, -5304/318)

The solution to the initial-value problem for x as a function of t, (2t³ - 2t² + t - 1)dx/dt = 3, is x = (1/3) t - 2/3.

To solve the initial-value problem for x as a function of t, we need to integrate the given differential equation with respect to t and apply the initial condition.

Let's proceed with the solution.

We have the differential equation:

(2t³ - 2t² + t - 1)dx/dt = 3

To solve this, we can start by separating the variables:

dx = 3 / (2t³ - 2t² + t - 1) dt

Now, we can integrate both sides:

∫dx = ∫(3 / (2t³ - 2t² + t - 1)) dt

Integrating the right side may require a more advanced technique such as partial fractions.

After integrating, we obtain:

x = ∫(3 / (2t³ - 2t² + t - 1)) dt + C

Next, we need to apply the initial condition x(2) = 0.

Substituting t = 2 and x = 0 into the equation, we can solve for the constant C:

0 = ∫(3 / (2(2)³ - 2(2)² + 2 - 1)) dt + C

0 = ∫(3 / (16 - 8 + 2 - 1)) dt + C

0 = ∫(3 / 9) dt + C

0 = (1/3) t + C

Solving for C, we find that C = -2/3.

Substituting the value of C back into the equation, we have:

x = (1/3) t - 2/3

Therefore, the solution to the initial-value problem is x = (1/3) t - 2/3.

The local maximum and minimum points of the curve represented by the function f(x) = 2x²/(x²-1) are (√2, f(√2)), and  (-√2, f(-√2)), respectively.

To find the local maximum and minimum points of the curve represented by the function f(x) = 2x²/(x²-1), we need to analyze the critical points and the behavior of the function around those points.

First, we find the derivative of the function f(x) with respect to x:

f'(x) = [2x²(x²-1) - 2x²(2x)] / (x²-1)²

= (2x⁴ - 2x² - 4x³ + 4x²) / (x²-1)²

To find the critical points, we set f'(x) equal to zero and solve for x:

(2x⁴ - 2x² - 4x³ + 4x²) / (x²-1)² = 0

Simplifying the numerator, we have:

2x²(x² - 2 - 2x) = 0

This equation has three solutions: x = 0, x = √2, and x = -√2.

Next, we analyze the behavior of the function f(x) around these critical points to determine if they correspond to local maximum or minimum points.

For x = 0, we observe that the function has a vertical asymptote at x = 1.

As x approaches 1 from the left, f(x) approaches negative infinity, and as x approaches 1 from the right, f(x) approaches positive infinity.

Therefore, there is no local maximum or minimum point at x = 0.

For x = √2 and x = -√2, we can analyze the sign changes of f'(x) around these points to determine the nature of the critical points.

By substituting test values into f'(x), we find that f'(x) is positive to the left of x = -√2, negative between x = -√2 and x = √2, and positive to the right of x = √2.

This indicates that x = -√2 corresponds to a local minimum point, and x = √2 corresponds to a local maximum point.

Therefore, the local maximum point is (√2, f(√2)), and the local minimum point is (-√2, f(-√2)).

Let's take the equation `(x − 7 )°y"(x) + cos²(x)y'(x) + (x − 7 ) y(x) = − 0`... (1)

We can write the given equation (1) as: `(x - 7) [ (x - 7) y''(x) + cos^2(x) y'(x) + y(x)] = 0`

Singular points of the given equation are:

This point is an irregular singular point because the coefficient `q(x)` has a second-order pole (i.e., `q(x) = cos²(x)`). Hence, this point is known as a turning point (because the coefficient `p(x)` is not zero at this point).

So, the singular points are `x = 7` (regular singular point) and `cos x = 0` (irregular singular point)

We have a differential equation given by: `(x − 7 )°y"(x) + cos²(x)y'(x) + (x − 7 ) y(x) = − 0`

1. To find the equation of the asymptotes of f, we need to examine the behavior of the function as x approaches positive or negative infinity. If the function approaches a specific value as x goes to infinity or negative infinity, then that value will be the equation of the asymptote.

2. Drawing the graph of f requires identifying the x-intercepts (where the function crosses the x-axis) and the y-intercept (where the function crosses the y-axis). Additionally, the asymptotes need to be plotted on the graph. The graph should show the shape of the function and the behavior near the asymptotes.

3. To determine the equation of g, which is a translation of f, we need to shift the graph of f 3 units to the left and 1 unit downwards. This means that every x-coordinate of f should be decreased by 3, and every y-coordinate should be decreased by 1.

4. The symmetry of f with respect to the y-axis means that if we reflect the graph of f across the y-axis, it should coincide with itself. This symmetry is characterized by the property that replacing x with -x in the equation of f should yield an equivalent equation.

The unit tangent vector T(t) and its derivative T'(t) are orthogonal vectors T'(t) that are perpendicular to each other.

The unit tangent vector T(t) of a two-differentiable function r(t) represents the direction of the curve at each point. The derivative of T(t), denoted as T'(t), represents the rate of change of the direction of the curve. Since T(t) is a unit vector, its magnitude is always 1. Taking the derivative of T(t) does not change its magnitude, but it affects its direction.

When we consider the derivative T'(t), it represents the change in direction of the curve. The derivative of a vector is orthogonal to the vector itself. Therefore, T'(t) is orthogonal to T(t). This means that the unit tangent vector and its derivative are perpendicular or orthogonal vectors.

To find the absolute maximum and absolute minimum values of `f` on the given interval [0, 3], we first need to find the critical values of `f`.Critical points are points where the derivative is equal to zero or undefined.

Here is the given function:

f(x) = x³ - 3x + 1

We need to find `f'(x)` by differentiating `f(x)` w.r.t `x`.f'(x) = 3x² - 3

Next, we need to solve the equation `f'(x) = 0` to find the critical points.

3x² - 3 = 0x² - 1 = 0(x - 1)(x + 1) = 0x = 1, x = -1

To find the recurrence relation for the coefficients of the power series solution, let's substitute the power series form into the differential equation and equate the coefficients of like powers of p.

Given the equation: p + (2l + 2 - 2p²) + (x - 3 - 2l) pu = 0

Let's assume the power series solution takes the form: u = Σk akp

Differentiating u with respect to p twice, we have:

d²u/dp² = Σk ak * d²pⁿ/dp²

The second derivative of p raised to the power n with respect to p can be calculated as follows:

d²pⁿ/dp² = n(n-1)p^(n-2)

Substituting this back into the expression for d²u/dp², we have:

d²u/dp² = Σk ak * n(n-1)p^(n-2)

Now let's substitute this expression for d²u/dp² and the power series form of u into the differential equation:

p + (2l + 2 - 2p²) + (x - 3 - 2l) * p * Σk akp = 0

Expanding and collecting like powers of p, we get:

Σk [(2k(k-1) + 1)ak + (2l + 2 - 2(k+1)²) * ak+1 + (x - 3 - 2l) * ak+2] * p^k = 0

Since the coefficient of each power of p must be zero, we obtain a recurrence relation for the coefficients:

(2k(k-1) + 1)ak + (2l + 2 - 2(k+1)²) * ak+1 + (x - 3 - 2l) * ak+2 = 0

To find the value of y(2), we need to solve the initial value problem and evaluate the solution at x = 2.

The given initial value problem is:

y' - y = x² + x

y(1) = 2

First, let's find the integrating factor for the homogeneous equation y' - y = 0. The integrating factor is given by e^(∫-1 dx), which simplifies to [tex]e^(-x).[/tex]

Next, we multiply the entire equation by the integrating factor: [tex]e^(-x) * y' - e^(-x) * y = e^(-x) * (x² + x)[/tex]

Applying the product rule to the left side, we get:

[tex](e^(-x) * y)' = e^(-x) * (x² + x)[/tex]

Integrating both sides with respect to x, we have:

∫ ([tex]e^(-x)[/tex]* y)' dx = ∫[tex]e^(-x)[/tex] * (x² + x) dx

Integrating the left side gives us:

[tex]e^(-x)[/tex] * y = -[tex]e^(-x)[/tex]* (x³/3 + x²/2) + C1

Simplifying the right side and dividing through by e^(-x), we get:

y = -x³/3 - x²/2 +[tex]Ce^x[/tex]

Now, let's use the initial condition y(1) = 2 to solve for the constant C:

2 = -1/3 - 1/2 + [tex]Ce^1[/tex]

2 = -5/6 + Ce

C = 17/6

Finally, we substitute the value of C back into the equation and evaluate y(2):

y = -x³/3 - x²/2 + (17/6)[tex]e^x[/tex]

y(2) = -(2)³/3 - (2)²/2 + (17/6)[tex]e^2[/tex]

y(2) = -8/3 - 2 + (17/6)[tex]e^2[/tex]

y(2) = -14/3 + (17/6)[tex]e^2[/tex]

According to the question For each iteration [tex]\(i = 1, 2, 3, \ldots\)[/tex] until we reach the desired value of [tex]\(x = 2\):[/tex]

Let's solve the given problems using cubic Lagrange interpolation and the Euler method.

(a) Cubic Lagrange Interpolation:

To find the value of [tex]\(y\) at \(x = \frac{1}{2}\)[/tex] using cubic Lagrange interpolation, we need to construct a cubic polynomial that passes through the given data points.

The given data points are:

[tex]\(x = \left[\frac{1}{3}, \frac{2}{3}, 2, \frac{5}{3}\right]\)[/tex]

[tex]\(y = \left[3, \frac{13}{4}, 3, \frac{5}{3}\right]\)[/tex]

The cubic Lagrange interpolation polynomial can be represented as:

[tex]\(P(x) = L_0(x)y_0 + L_1(x)y_1 + L_2(x)y_2 + L_3(x)y_3\)[/tex]

where [tex]\(L_i(x)\)[/tex] are the Lagrange basis polynomials.

The Lagrange basis polynomials are given by:

[tex]\(L_0(x) = \frac{(x - x_1)(x - x_2)(x - x_3)}{(x_0 - x_1)(x_0 - x_2)(x_0 - x_3)}\)[/tex]

[tex]\(L_1(x) = \frac{(x - x_0)(x - x_2)(x - x_3)}{(x_1 - x_0)(x_1 - x_2)(x_1 - x_3)}\)[/tex]

[tex]\(L_2(x) = \frac{(x - x_0)(x - x_1)(x - x_3)}{(x_2 - x_0)(x_2 - x_1)(x_2 - x_3)}\)[/tex]

[tex]\(L_3(x) = \frac{(x - x_0)(x - x_1)(x - x_2)}{(x_3 - x_0)(x_3 - x_1)(x_3 - x_2)}\)[/tex]

Substituting the given values, we have:

[tex]\(x_0 = \frac{1}{3}, x_1 = \frac{2}{3}, x_2 = 2, x_3 = \frac{5}{3}\)[/tex]

[tex]\(y_0 = 3, y_1 = \frac{13}{4}, y_2 = 3, y_3 = \frac{5}{3}\)[/tex]

Substituting these values into the Lagrange basis polynomials, we get:

[tex]\(L_0(x) = \frac{(x - \frac{2}{3})(x - 2)(x - \frac{5}{3})}{(\frac{1}{3} - \frac{2}{3})(\frac{1}{3} - 2)(\frac{1}{3} - \frac{5}{3})}\)[/tex]

[tex]\(L_1(x) = \frac{(x - \frac{1}{3})(x - 2)(x - \frac{5}{3})}{(\frac{2}{3} - \frac{1}{3})(\frac{2}{3} - 2)(\frac{2}{3} - \frac{5}{3})}\)[/tex]

[tex]\(L_2(x) = \frac{(x - \frac{1}{3})(x - \frac{2}{3})(x - \frac{5}{3})}{(2 - \frac{1}{3})(2 - \frac{2}{3})(2 - \frac{5}{3})}\)[/tex]

[tex]\(L_3(x) = \frac{(x\frac{1}{3})(x - \frac{2}{3})(x - 2)}{(\frac{5}{3} - \frac{1}{3})(\frac{5}{3} - \frac{2}{3})(\frac{5}{3} - 2)}\)[/tex]

Now, we can substitute [tex]\(x = \frac{1}{2}\)[/tex] into the cubic Lagrange interpolation polynomial:

[tex]\(P\left(\frac{1}{2}\right) = L_0\left(\frac{1}{2}\right)y_0 + L_1\left(\frac{1}{2}\right)y_1 + L_2\left(\frac{1}{2}\right)y_2 + L_3\left(\frac{1}{2}\right)y_3\)[/tex]

Substituting the calculated values, we can find the value of [tex]\(y\) at \(x = \frac{1}{2}\).[/tex]

(b) Euler Method:

(i) Using Euler's method, we can approximate the solution to the initial value problem:

[tex]\(\frac{dy}{dx} = y - x^2 + 1\)[/tex]

[tex]\(y(0) = 0.5\)[/tex]

We are asked to compute [tex]\(y(2)\)[/tex] using a step size [tex]\(h = 0.4\).[/tex]

Euler's method can be applied as follows:

Step 1: Initialize the values

[tex]\(x_0 = 0\)[/tex] (initial value of [tex]\(x\))[/tex]

[tex]\(y_0 = 0.5\)[/tex] (initial value of [tex]\(y\))[/tex]

Step 2: Iterate using Euler's method

For each iteration [tex]\(i = 1, 2, 3, \ldots\)[/tex] until we reach the desired value of [tex]\(x = 2\):[/tex]

[tex]\(x_i = x_{i-1} + h\)[/tex] (increment [tex]\(x\)[/tex] by the step size [tex]\(h\))[/tex]

[tex]\(y_i = y_{i-1} + h \cdot (y_{i-1} - (x_{i-1})^2 + 1)\)[/tex]

Continue iterating until [tex]\(x = 2\)[/tex] is reached.

(ii) Using Heun's method, we can also approximate the solution to the initial value problem using the same step size [tex]\(h = 0.4\).[/tex]

Heun's method can be applied as follows:

Step 1: Initialize the values

[tex]\(x_0 = 0\) (initial value of \(x\))[/tex]

[tex]\(y_0 = 0.5\) (initial value of \(y\))[/tex]

Step 2: Iterate using Heun's method

For each iteration [tex]\(i = 1, 2, 3, \ldots\)[/tex] until we reach the desired value of [tex]\(x = 2\):[/tex]

[tex]\(x_i = x_{i-1} + h\) (increment \(x\) by the step size \(h\))[/tex]

[tex]\(k_1 = y_{i-1} - (x_{i-1})^2 + 1\) (slope at \(x_{i-1}\))[/tex]

[tex]\(k_2 = y_{i-1} + h \cdot k_1 - (x_i)^2 + 1\) (slope at \(x_i\) using \(k_1\))[/tex]

[tex]\(y_i = y_{i-1} + \frac{h}{2} \cdot (k_1 + k_2)\)[/tex]

Both methods, definition of surface integrals and evaluating the triple integral, yield the same result of zero, indicating that the surface integral of the vector field F over the unit sphere is zero.

The surface integral of the given vector field over the unit sphere can be computed using the definition of surface integrals or by evaluating the triple integral of an appropriate function.

a. Using the definition of surface integrals:

The outward normal at any point (x, y, z) on the unit sphere is a multiple of (x, y, z), which can be written as n = k(x, y, z), where k is a constant.

The surface integral is then given by:

∬S F · dS = ∬S (x(y² - 2² + 1)i + y(2² - x² + 1)j + z(x² - y² + 1)k) · (k(x, y, z) dS)

Since the unit sphere has radius 1, we can write dS = dA, where dA represents the area element on the sphere's surface.

The dot product between the vector field F and the outward normal k(x, y, z) simplifies to:

F · n = (x(y² - 2² + 1) + y(2² - x² + 1) + z(x² - y² + 1))k

By substituting dS = dA and integrating over the surface of the unit sphere, we have:

∬S F · dS = k ∬S (x(y² - 2² + 1) + y(2² - x² + 1) + z(x² - y² + 1)) dA

Integrating this expression over the unit sphere will result in zero since the integrand is an odd function with respect to each variable (x, y, z) and the sphere is symmetric.

b. Evaluating the triple integral:

Alternatively, we can compute the surface integral by evaluating the triple integral of an appropriate function over the region enclosed by the unit sphere.

Let's consider the function g(x, y, z) = x(y² - 2² + 1) + y(2² - x² + 1) + z(x² - y² + 1).

By using the divergence theorem, the triple integral of g(x, y, z) over the region enclosed by the unit sphere is equal to the surface integral of F over the unit sphere.

Applying the divergence theorem, we have:

∬S F · dS = ∭V ∇ · F dV

Since the divergence of F is zero (∇ · F = 0), the triple integral evaluates to zero.

Therefore, both methods yield the same result of zero, indicating that the surface integral of the vector field F over the unit sphere is zero.

Therefore, the double integral ∬D xy dA over the region D in the first quadrant bounded by x = 0, y = 0, and the circle x² + y² = 4 is equal to 1.

To evaluate the double integral ∬D xy dA over the region D in the first quadrant bounded by x = 0, y = 0, and the circle x² + y² = 4, we need to express the integral in polar coordinates.

In polar coordinates, the equation of the circle x² + y² = 4 can be written as r² = 4, where r represents the radial distance from the origin.

Since we are in the first quadrant, the limits of integration for the polar angle θ are from 0 to π/2.

The limits for the radial distance r can be determined by considering the circle x² + y² = 4. When x = 0, we have y = 2 or y = -2. Thus, the limits for r are from 0 to 2.

The double integral in polar coordinates is then given by:

∬D xy dA = ∫₀^(π/2) ∫₀² (r cosθ)(r sinθ) r dr dθ

Simplifying the integrand:

∫₀^(π/2) ∫₀² r³ cosθ sinθ dr dθ

Now, we can integrate with respect to r:

∫₀² r³ cosθ sinθ dr = (1/4) cosθ sinθ [r⁴]₀² = (1/4) cosθ sinθ (16 - 0) = 4 cosθ sinθ

Substituting this result back into the integral:

∫₀^(π/2) 4 cosθ sinθ dθ

Integrating with respect to θ:

∫₀^(π/2) 4 cosθ sinθ dθ = 4 (1/2) sin²θ [θ]₀^(π/2) = 2 (1/2) (1 - 0) = 1

Therefore, the double integral ∬D xy dA over the region D in the first quadrant bounded by x = 0, y = 0, and the circle x² + y² = 4 is equal to 1.

We are required to determine the power series for the given functions centered at c and determine the interval of convergence for each function.

a) f(x) = 7²-3; c=5

Here, we can write 7²-3 as 48.

So, we have to find the power series of 48 centered at 5.

The power series for any constant is the constant itself.

So, the power series for 48 is 48 itself.

The interval of convergence is also the point at which the series converges, which is only at x = 5.

Hence the interval of convergence for the given function is [5, 5].

b) f(x) = 2x² +3² ; c=0

Here, we can write 3² as 9.

So, we have to find the power series of 2x²+9 centered at 0.

Using the power series for x², we can write the power series for 2x² as 2x² = 2(x^2).

Now, the power series for 2x²+9 is 2(x^2) + 9.

For the interval of convergence, we can find the radius of convergence R using the formula:

`R= 1/lim n→∞|an/a{n+1}|`,

where an = 2ⁿ/n!

Using this formula, we can find that the radius of convergence is ∞.

Hence the interval of convergence for the given function is (-∞, ∞).c) f(x)=- d) f(x)=- ; c=3

Here, the functions are constant and equal to 0.

So, the power series for both functions would be 0 only.

For both functions, since the power series is 0, the interval of convergence would be the point at which the series converges, which is only at x = 3.

Hence the interval of convergence for both functions is [3, 3].

The given problem can be formulated as a linear programming problem with the objective function p = 3x + 3y + 3z + 3w + 3v and the following constraints:

1. x + y ≤ 3

2. y + z ≤ 6

3. z + w ≤ 9

4. w + v ≤ 12

5. x ≥ 0, y ≥ 0, z ≥ 0, w ≥ 0, v ≥ 0

To find the maximum value of p, we need to identify the corner points of the feasible region defined by these constraints. We can solve the system of inequalities to determine the feasible region.

Given the point (x, y, z, w, v) = (0, 21, 0, 24, 0), we can substitute these values into the objective function p to obtain:

p = 3(0) + 3(21) + 3(0) + 3(24) + 3(0) = 3(21 + 24) = 3(45) = 135.

Therefore, at the point (0, 21, 0, 24, 0), the value of p is 135.

The given function is:

S(T) = {0, T < 273,

σT^4/273^4,

T ≥ 273, where σ = 5.67 x 10^−8 is the Stefan-Boltzmann constant.

To prove that limT→273S(T) ≠ 0, it is required to use the ε-δ definition of the limit:

∃ε > 0, such that ∀

δ > 0, ∃T, such that |T - 273| < δ, but |S(T)| ≥ ε.

Now assume that

limT→273S(T) = 0

Therefore,∀ε > 0, ∃δ > 0, such that ∀T, if 0 < |T - 273| < δ, then |S(T)| < ε.

Now, let ε = σ/100. Then there must be a δ > 0 such that,

if |T - 273| < δ, then

|S(T)| < σ/100.

Let T0 be any number such that 273 < T0 < 273 + δ.

Then S(T0) > σT0^4

273^4 > σ(273 + δ)^4

273^4 = σ(1 + δ/273)^4.

Now,

(1 + δ/273)^4 = 1 + 4δ/273 + 6.29 × 10^−5 δ^2/273^2 + 5.34 × 10^−7 δ^3/273^3 + 1.85 × 10^−9 δ^4/273^4 ≥ 1 + 4δ/273

For δ < 1, 4δ/273 < 4/273 < 1/100.

Thus,

(1 + δ/273)^4 > 1 + 1/100, giving S(T0) > 1.01σ/100.

This contradicts the assumption that

|S(T)| < σ/100 for all |T - 273| < δ. Hence, limT→273S(T) ≠ 0.

The projectile reaches its height after 30 seconds, 2 inches of rainfall produces number of mosquitoes, 4 thousand automobiles needed to minimize cost, and 300 pretzels must be sold to maximize profit.

To find the time it takes for the projectile to reach its maximum height, we need to determine the time at which the velocity becomes zero. Since the projectile is thrown upward, the initial velocity is positive and the acceleration is negative due to gravity. The velocity function is v(t) = h'(t) = 360 - 12t. Setting v(t) = 0 and solving for t, we get 360 - 12t = 0. Solving this equation, we find t = 30 seconds. Therefore, the projectile reaches its maximum height after 30 seconds.To find the rainfall that produces the maximum number of mosquitoes, we need to maximize the function M(x) = 4x - x^2. Since this is a quadratic function, we can find the maximum by determining the vertex. The x-coordinate of the vertex can be found using the formula x = -b/(2a), where a = -1 and b = 4. Plugging these values into the formula, we get x = -4/(2*(-1)) = 2 inches of rainfall. Therefore, 2 inches of rainfall produces the maximum number of mosquitoes.

To minimize the cost of manufacturing automobiles, we need to find the number of automobiles that minimizes the cost function C(x) = 3x^2 - 24x + 144. Since this is a quadratic function, the minimum occurs at the vertex. The x-coordinate of the vertex can be found using the formula x = -b/(2a), where a = 3 and b = -24. Plugging these values into the formula, we get x = -(-24)/(2*3) = 4 thousand automobiles. Therefore, 4 thousand automobiles must be produced to minimize the cost.

To maximize the profit from selling pretzels, we need to find the number of pretzels that maximizes the profit function P(x) = -0.004x^2 + 2.4x - 350. Since this is a quadratic function, the maximum occurs at the vertex. The x-coordinate of the vertex can be found using the formula x = -b/(2a), where a = -0.004 and b = 2.4. Plugging these values into the formula, we get x = -2.4/(2*(-0.004)) = 300 pretzels. Therefore, 300 pretzels must be sold to maximize the profit.

The marginal profit function represents the rate of change of profit with respect to the number of magazines sold. To find the marginal profit function, we need to calculate the derivative of the profit function.

The profit function is given by P(x) = R(x) - C(x), where R(x) is the revenue function and C(x) is the cost function.

The revenue function R(x) is given by R(x) = p(x) * x, where p(x) is the price function.

Given that p(x) = 4.600.0006x, the revenue function becomes R(x) = 4.600.0006x * x = 4.600.0006x².

The cost function is given by C(x) = 0.0005x² + x + 4000.

Now, we can calculate the profit function:

P(x) = R(x) - C(x) = 4.600.0006x² - (0.0005x² + x + 4000)

      = 4.5995006x² - x - 4000.

Finally, we can find the marginal profit function by taking the derivative of the profit function:

P'(x) = (d/dx)(4.5995006x² - x - 4000)

       = 9.1990012x - 1.

Sarah made a deposit of $1267.00 into a bank account that earns interest at a rate of 8.8% compounded monthly for a period of five years. We need to calculate the balance of the account at the end of the period.

To find the balance at the end of the period, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A is the final amount (balance)

P is the principal (initial deposit)

r is the annual interest rate (as a decimal)

n is the number of times interest is compounded per year

t is the number of years

In this case, Sarah's deposit is $1267.00, the interest rate is 8.8% (or 0.088 as a decimal), the interest is compounded monthly (n = 12), and the period is five years (t = 5).

Plugging the values into the formula, we have:

A = 1267(1 + 0.088/12)^(12*5)

Calculating the expression inside the parentheses first:

(1 + 0.088/12) ≈ 1.007333

Substituting this back into the formula:

A ≈ 1267(1.007333)^(60)

Evaluating the exponent:

(1.007333)^(60) ≈ 1.517171

Finally, calculating the balance:

A ≈ 1267 * 1.517171 ≈ $1924.43

Therefore, the balance of the account at the end of the five-year period is approximately $1924.43.

For part (b), to find the interest earned, we subtract the initial deposit from the final balance:

Interest = A - P = $1924.43 - $1267.00 ≈ $657.43

The interest earned is approximately $657.43.

For part (c), the effective rate of interest takes into account the compounding frequency. In this case, the interest is compounded monthly, so the effective rate can be calculated using the formula:

Effective rate = (1 + r/n)^n - 1

Substituting the values:

Effective rate = (1 + 0.088/12)^12 - 1 ≈ 0.089445

Therefore, the effective rate of interest is approximately 8.9445%.A.
