Answer 1

Permutation = 126. There are 126 different dinners available if a dinner consists of one appetizer, one salad, one entree, and one dessert. Given, An upscale restaurant offers a special fixe prix menu in which, for a fixed dinner cost, a diner can select from two appetizers, three salads, three entrees, and seven desserts.

For a dinner, we need to select one appetizer, one salad, one entree, and one dessert.

The number of ways of selecting a dinner is the product of the number of ways of selecting an appetizer, salad, entree, and dessert.

Number of ways of selecting an appetizer = 2

Number of ways of selecting a salad = 3

Number of ways of selecting an entree = 3

Number of ways of selecting a dessert = 7

Number of ways of selecting a dinner

Use the table of integrals to evaluate the integral. (Use C for the constant of integration.) S 9 sec² (0) tan²(0) 81 - tan² (8) de

Answers

The given integral, ∫(81 - tan²(8))de, can be evaluated using the table of integrals. The result is 81e - (8e + 8tan(8)). (Note: The constant of integration, C, is omitted in the answer.)

To evaluate the integral, we use the table of integrals. The integral of a constant term, such as 81, is simply the constant multiplied by the variable of integration, which in this case is e. Therefore, the integral of 81 is 81e.

For the term -tan²(8), we refer to the table of integrals for the integral of the tangent squared function. The integral of tan²(x) is x - tan(x). Applying this rule, the integral of -tan²(8) is -(8) - tan(8), which simplifies to -8 - tan(8).

Putting the results together, we have ∫(81 - tan²(8))de = 81e - (8e + 8tan(8)). It's important to note that the constant of integration, C, is not included in the final answer, as it was omitted in the given problem statement.

Answers

To find the partial derivatives of z with respect to x and y, we will use implicit differentiation. The given equation is cos(az) = ex + yz. By differentiating both sides of the equation with respect to x and y, we can solve for ǝx and ǝy.

We are given the equation cos(az) = ex + yz. To find ǝx and ǝy, we differentiate both sides of the equation with respect to x and y, respectively, treating z as a function of x and y.

Differentiating with respect to x:

-az sin(az)(ǝa/ǝx) = ex + ǝz/ǝx.

Simplifying and solving for ǝz/ǝx:

ǝz/ǝx = (-az sin(az))/(ex).

Similarly, differentiating with respect to y:

-az sin(az)(ǝa/ǝy) = y + ǝz/ǝy.

Simplifying and solving for ǝz/ǝy:

ǝz/ǝy = (-azsin(az))/y.

Therefore, the partial derivatives of z with respect to x and y are ǝz/ǝx = (-az sin(az))/(ex) and ǝz/ǝy = (-az sin(az))/y, respectively.

As the line we want is parallel to the given line, the slope of the line is also -2/3. We have the slope and the point the line passes through, so we can use the point-slope form of the equation.y - y1 = m(x - x1)y - 4 = -2/3(x + 3)y = -2/3x +

For what values of the variable does the series converge? Use the properties of geometric series to find the sum of the series when it converges. 200+80x2 + 320x3 + 1280x4 +... sum = ___________

Answers

The geometric series converges to the sum of 1000 when the variable is in the range of |r|<1. Therefore, the values of the variable that allow the series to converge are: 0 < x < 1.25.

When it comes to the convergence of a series, it is important to use the properties of geometric series in order to get the values of the variable that allows for the series to converge. Therefore, we should consider the following series:

200 + 80x2 + 320x3 + 1280x4 + …

To determine the values of the variable that will make the above series converge, we must use the necessary formulae that are given below:

(1) If |r| < 1, the series converges to a/(1-r).

(2) The series diverges to infinity if |r| ≥ 1.

Let us proceed with the given series and see if it converges or diverges using the formulae we mentioned. We can write the above series as:

200 + 80x2 + 320x3 + 1280x4 + …= ∑200(4/5) n-1.

As we can see, a=200 and r= 4/5. So, we can apply the formula as follows:

|4/5|<1Hence, the above series converges to sum a/(1-r), which is equal to 200/(1-4/5) = 1000. Therefore, the sum of the above series is 1000.

The above series converges to the sum of 1000 when the variable is in the range of |r|<1. Therefore, the variable values that allow the series to converge are 0 < x < 1.25.

Prove that |1-wz|² -|z-w|² = (1-|z|³²)(1-|w|²³). 7. Let z be purely imaginary. Prove that |z-1|=|z+1).

Answers

The absolute value only considers the magnitude of a complex number and not its sign, we can conclude that |z - 1| = |z + 1| when z is purely imaginary.

To prove the given identity |1 - wz|² - |z - w|² = (1 - |z|³²)(1 - |w|²³), we can start by expanding the squared magnitudes on both sides and simplifying the expression.

Let's assume z and w are complex numbers.

On the left-hand side:

|1 - wz|² - |z - w|² = (1 - wz)(1 - wz) - (z - w)(z - w)

Expanding the squares:

= 1 - 2wz + (wz)² - (z - w)(z - w)

= 1 - 2wz + (wz)² - (z² - wz - wz + w²)

= 1 - 2wz + (wz)² - z² + 2wz - w²

= 1 - z² + (wz)² - w²

Now, let's look at the right-hand side:

(1 - |z|³²)(1 - |w|²³) = 1 - |z|³² - |w|²³ + |z|³²|w|²³

Since z is purely imaginary, we can write it as z = bi, where b is a real number. Similarly, let w = ci, where c is a real number.

Substituting these values into the right-hand side expression:

1 - |z|³² - |w|²³ + |z|³²|w|²³

= 1 - |bi|³² - |ci|²³ + |bi|³²|ci|²³

= 1 - |b|³²i³² - |c|²³i²³ + |b|³²|c|²³i³²i²³

= 1 - |b|³²i - |c|²³i + |b|³²|c|²³i⁵⁵⁶

= 1 - bi - ci + |b|³²|c|²³i⁵⁵⁶

Since i² = -1, we can simplify the expression further:

1 - bi - ci + |b|³²|c|²³i⁵⁵⁶

= 1 - bi - ci - |b|³²|c|²³

= 1 - (b + c)i - |b|³²|c|²³

Comparing this with the expression we obtained on the left-hand side:

1 - z² + (wz)² - w²

We see that both sides have real and imaginary parts. To prove the identity, we need to show that the real parts are equal and the imaginary parts are equal.

Comparing the real parts:

1 - z² = 1 - |b|³²|c|²³

This equation holds true since z is purely imaginary, so z² = -|b|²|c|².

Comparing the imaginary parts:

2wz + (wz)² - w² = - (b + c)i - |b|³²|c|²³

This equation also holds true since w = ci, so - 2wz + (wz)² - w² = - 2ci² + (ci²)² - (ci)² = - c²i + c²i² - ci² = - c²i + c²(-1) - c(-1) = - (b + c)i.

Since both the real and imaginary parts are equal, we have shown that |1 - wz|² - |z - w|² = (1 - |z|³²)(1 - |w|²³), as desired.

To prove that |z - 1| = |z + 1| when z is purely imaginary, we can use the definition of absolute value (magnitude) and the fact that the imaginary part of z is nonzero.

Let z = bi, where b is a real number and i is the imaginary unit.

Then,

|z - 1| = |bi - 1| = |(bi - 1)(-1)| = |-bi + 1| = |1 - bi|

Similarly,

|z + 1| = |bi + 1| = |(bi + 1)(-1)| = |-bi - 1| = |1 + bi|

Notice that both |1 - bi| and |1 + bi| have the same real part (1) and their imaginary parts are the negatives of each other (-bi and bi, respectively).

Since the absolute value only considers the magnitude of a complex number and not its sign, we can conclude that |z - 1| = |z + 1| when z is purely imaginary.

Factor x¹6 x into irreducible factors over the following fields. 16. (a) GF(2). (b) GF(4). (c) GF(16).

Answers

The factorization of x¹6x into irreducible factors over the fields GF(2), GF(4) and GF(16) has been provided. The polynomial x¹6x is reducible over GF(2) as it has a factor of x. Thus, x¹6x factors into x²(x¹4 + 1). x¹4 + 1 is an irreducible polynomial over GF(2).

The factorization of x¹6x into irreducible factors over the following fields is provided below.

a. GF(2)

The polynomial x¹6x is reducible over GF(2) as it has a factor of x. Thus, x¹6x factors into x²(x¹4 + 1). x¹4 + 1 is an irreducible polynomial over GF(2).

b. GF(4)

Over GF(4), the polynomial x¹6x factors as x(x¹2 + x + 1)(x¹2 + x + a), where a is the residue of the element x¹2 + x + 1 modulo x¹2 + x + 1. Then, x¹2 + x + 1 is irreducible over GF(2), so x(x¹2 + x + 1)(x¹2 + x + a) is the factorization of x¹6x into irreducible factors over GF(4).

c. GF(16)

Over GF(16), x¹6x = x¹8(x⁸ + x⁴ + 1) = x¹8(x⁴ + x² + x + a)(x⁴ + x² + ax + a³), where a is the residue of the element x⁴ + x + 1 modulo x⁴ + x³ + x + 1. Then, x⁴ + x² + x + a is irreducible over GF(4), so x¹6x factors into irreducible factors over GF(16) as x¹8(x⁴ + x² + x + a)(x⁴ + x² + ax + a³).

Thus, the factorization of x¹6x into irreducible factors over the fields GF(2), GF(4) and GF(16) has been provided.

Answers

The limit of f(x) as x approaches -1 does not exist.

To determine the limit of f(x) as x approaches -1, we need to examine the behavior of the function as x gets arbitrarily close to -1. From the given graph, we can see that when x approaches -1 from the left side (x < -1), the function approaches a value of 2. However, when x approaches -1 from the right side (x > -1), the function approaches a value of -1.

Since the left-hand and right-hand limits of f(x) as x approaches -1 are different, the limit of f(x) as x approaches -1 does not exist. The function does not approach a single value from both sides, indicating that there is a discontinuity at x = -1. This can be seen as a jump in the graph where the function abruptly changes its value at x = -1.

Therefore, the limit of f(x) as x approaches -1 is said to be "DNE" (does not exist) due to the discontinuity at that point.

Answers

The specific trajectory that models the situation when the rabbit population is currently 2000 and the fox population is currently 400 is x²/2 - 5x + 40 = t.

To find the equilibrium points of the given Volterra-Lotka model, we must set x' = y' = 0 and solve for x and y. Using the given model,x² = αx - Bxy ⇒ x(x - α + By) = 0.

We have two solutions: x = 0 and x = α - By.Now, ly' = yxy - Sy = y(yx - S) ⇒ y'(1/ y) = xy - S ⇒ y' = xy² - Sy.

Differentiating y' with respect to y, we obtainx(2y) - S = 0 ⇒ y = S/2x, which is the other equilibrium point.b. To obtain an implicit formula for the general trajectory of the system, we will solve the differential equationx' = αx - Bxy ⇒ x'/x = α - By,

using separation of variables, we obtainx/ (α - By) dx = dtIntegrating both sides,x²/2 - αxy/B = t + C1,where C1 is the constant of integration.

To solve for the value of C1, we can use the initial conditions given in the problem when t = 0, x = x0 and y = y0.

Thus,x0²/2 - αx0y0/B = C1.Substituting C1 into the general solution equation, we obtainx²/2 - αxy/B = t + x0²/2 - αx0y0/B.

which is the implicit formula for the general trajectory of the system.c.

Given that the rabbit population is currently 2000 and the fox population is currently 400, we can solve for the values of x0 and y0 to obtain the specific trajectory that models the situation. Thus,x0 = 2000/100 = 20 and y0 = 400/100 = 4.Substituting these values into the implicit formula, we obtainx²/2 - 5x + 40 = t.We can graph this solution using a computer system.

The direction of the trajectory is clockwise, as can be seen in the attached graph.d. To find the maximum population that rabbits will reach, we must find the maximum value of x. Taking the derivative of x with respect to t, we obtainx' = αx - Bxy = x(α - By).

The maximum value of x will occur when x' = 0, which happens when α - By = 0 ⇒ y = α/B.Substituting this value into the expression for x, we obtainx = α - By = α - α/B = α(1 - 1/B).Using the given values of α and B, we obtainx = 20(1 - 1/10) = 18.Therefore, the maximum population that rabbits will reach is 1800 (in hundreds).
At that time, the fox population will be y = α/B = 20/10 = 2 (in hundreds).

The Volterra-Lotka model states that a predator-prey relationship can be modeled by: (x² = αx - - Bxy ly' = yxy - Sy. Suppose that x represents the population (in hundreds) of rabbits on an island, and y represents the population (in hundreds) of foxes.

A scientist models the populations by using a Volterra-Lotka model with a = 20, p= 10, y = 2,8 = 30. The equilibrium points of this model are x = 0, x = α - By, y = S/2x.

The implicit formula for the general trajectory of the system from part a is given by x²/2 - αxy/B = t + x0²/2 - αx0y0/B.

The specific trajectory that models the situation when the rabbit population is currently 2000 and the fox population is currently 400 is x²/2 - 5x + 40 = t.

The direction of the trajectory is clockwise.The maximum population that rabbits will reach is 1800 (in hundreds). At that time, the fox population will be 2 (in hundreds).

Thus, the Volterra-Lotka model can be used to model a predator-prey relationship, and the equilibrium points, implicit formula for the general trajectory, and specific trajectory can be found for a given set of parameters.

Let f(x) = = 7x¹. Find f(4)(x). -7x4 1-x

Answers

The expression f(4)(x) = -7x4(1 - x) represents the fourth derivative of the function f(x) = 7x1, which can be written as f(4)(x).

To calculate the fourth derivative of the function f(x) = 7x1, we must use the derivative operator four times. This is necessary in order to discover the answer. Let's break down the procedure into its individual steps.

First derivative: f'(x) = 7 * 1 * x^(1-1) = 7

The second derivative is expressed as follows: f''(x) = 0 (given that the derivative of a constant is always 0).

Because the derivative of a constant is always zero, the third derivative can be written as f'''(x) = 0.

Since the derivative of a constant is always zero, we write f(4)(x) = 0 to represent the fourth derivative.

As a result, the value of the fourth derivative of the function f(x) = 7x1 cannot be different from zero. It is essential to point out that the formula "-7x4(1 - x)" does not stand for the fourth derivative of the equation f(x) = 7x1, as is commonly believed.

Answers

The plane is changing direction from going up to going down when its velocity changes from positive to negative and from going down to going up when its velocity changes from negative to positive.

Sketching the graph of the piecewise function h(t) representing the relationship between height and time during the 20 seconds: The graph of the piecewise function h(t) is as shown below: We can obtain the local minima and maxima for the intervals of increase or decrease and other specific coordinates as below:

When 0 ≤ t < 5, there is a local maximum at (1.38, 655.78) and a local minimum at (3.68, 140.45).When 5 ≤ t ≤ 12, the function is decreasing

When 12 < t ≤ 20, there is a local maximum at (14.09, 4101.68)b. The acceleration when t = 2 seconds can be determined using the second derivative of h(t) with respect to t as follows:

h(t) = {21-81³-412+241 + 435} = -81t³ + 412t² + 241t + 435dh(t)/dt = -243t² + 824t + 241d²h(t)/dt² = -486t + 824

When t = 2, the acceleration of the plane is given by:d²h(t)/dt² = -486t + 824 = -486(2) + 824 = -148 ms⁻²e.

The plane is changing direction from going up to going down when its velocity changes from positive to negative and from going down to going up when its velocity changes from negative to positive.

Therefore, the plane is changing direction from going up to going down when its velocity changes from positive to negative and from going down to going up when its velocity changes from negative to positive.

Hence, the plane changes direction at the point where its velocity is equal to zero.

When 0 ≤ t < 5, the plane changes direction from going up to going down at the point where the velocity is equal to zero.

The velocity can be obtained by differentiating the height function as follows :h(t) = {21-81³-412+241 + 435} = -81t³ + 412t² + 241t + 435v(t) = dh(t)/dt = -243t² + 824t + 2410 = - 1/3 (824 ± √(824² - 4(-243)(241))) / 2(-243) = 2.84 sec (correct to two decimal places)

d. The lowest and highest altitudes of the airplane during the interval [0, 20] s. can be determined by finding the absolute minimum and maximum values of the piecewise function h(t) over the given interval. Therefore, we find the absolute minimum and maximum values of the function over each interval and then compare them to obtain the lowest and highest altitudes over the entire interval. For 0 ≤ t < 5, we have: Minimum occurs at t = 3.68 seconds Minimum value = h(3.68) = -400.55

Maximum occurs at t = 4.62 seconds Maximum value = h(4.62) = 669.09For 5 ≤ t ≤ 12, we have:

Minimum occurs at t = 5 seconds

Minimum value = h(5) = 241Maximum occurs at t = 12 seconds Maximum value = h(12) = 2129For 12 < t ≤ 20, we have:

Minimum occurs at t = 12 seconds

Minimum value = h(12) = 2129Maximum occurs at t = 17.12 seconds

Maximum value = h(17.12) = 4178.95Therefore, the lowest altitude of the airplane during the interval [0, 20] seconds is -400.55 m, and the highest altitude of the airplane during the interval [0, 20] seconds is 4178.95 m.e.

Therefore, the plane is speeding up while the velocity is decreasing during the interval 1.38 s < t < 1.69 s.f. The plane is slowing down while the velocity is increasing when the second derivative of h(t) with respect to t is negative and the velocity is positive.

Therefore, we need to find the intervals of time when the second derivative is negative and the velocity is positive.

Therefore, the plane is slowing down while the velocity is increasing during the interval 5.03 s < t < 5.44 seconds.g.

The maximum speed of the plane during the first 4 seconds: t e[0,4] can be determined by finding the maximum value of the absolute value of the velocity function v(t) = dh(t)/dt over the given interval.

Therefore, we need to find the absolute maximum value of the velocity function over the interval 0 ≤ t ≤ 4 seconds.

When 0 ≤ t < 5, we have: v(t) = dh(t)/dt = -243t² + 824t + 241

Maximum occurs at t = 1.38 seconds

Maximum value = v(1.38) = 1871.44 ms⁻¹Therefore, the maximum speed of the plane during the first 4 seconds is 1871.44 m/s.

Suppose that the number of atoms of a particular isotope at time t (in hours) is given by the exponential decay function f(t) = e-0.88t By what factor does the number of atoms of the isotope decrease every 25 minutes? Give your answer as a decimal number to three significant figures. The factor is

Answers

The number of atoms of the isotope decreases by a factor of approximately 0.682 every 25 minutes. This means that after 25 minutes, only around 68.2% of the original number of atoms will remain.

The exponential decay function given is f(t) = e^(-0.88t), where t is measured in hours. To find the factor by which the number of atoms decreases every 25 minutes, we need to convert 25 minutes into hours.

There are 60 minutes in an hour, so 25 minutes is equal to 25/60 = 0.417 hours (rounded to three decimal places). Now we can substitute this value into the exponential decay function:

[tex]f(0.417) = e^{(-0.88 * 0.417)} = e^{(-0.36696)} =0.682[/tex] (rounded to three significant figures).

Answers

To determine the limit, we can simplify the expression inside the limit notation and analyze the behavior as x approaches infinity.

The given expression is:

lim(x->∞) (24x³ + 4x² - 2x) / (28x + x + 5x + 5)

Simplifying the expression:

lim(x->∞) (24x³ + 4x² - 2x) / (34x + 5)

As x approaches infinity, the highest power term dominates the expression. In this case, the highest power term is 24x³ in the numerator and 34x in the denominator. Thus, we can neglect the lower order terms.

The simplified expression becomes:

lim(x->∞) (24x³) / (34x)

Now we can cancel out the common factor of x:

lim(x->∞) (24x²) / 34

Simplifying further:

lim(x->∞) (12x²) / 17

As x approaches infinity, the limit evaluates to infinity:

lim(x->∞) (12x²) / 17 = ∞

Therefore, the correct choice is:

In the given problem, the function f(x) = x - 8 is defined. We need to find the limit of f(x) as x approaches 8.

To find the limit, we substitute the value 8 into the function f(x):

lim f(x) = lim (x - 8) = 8 - 8 = 0

Therefore, the limit of f(x) as x approaches 8 is 0.

b) The correct choice is B. The limit does not exist.

We are asked to find the limit of f(x) as x approaches 0. Let's substitute 0 into the function:

Answers

The eigenvalues of the matrix are 21, 22, and 23. The matrix is diagonalizable. So, the answer is Yes.

T: P2 P₂ is defined by T(ao + a₁x + a₂x²) = (−3a₁ + 5a₂) + (-4a0 + 4a₁ - 10a₂)x+ 5a₂x².

We need to find the eigenvalues of the matrix, the corresponding coordinate eigenvectors of T relative to the standard basis {1, x, x²}, and whether the matrix is diagonalizable or not.

Eigenvalues: We know that the eigenvalues of the matrix are given by the roots of the characteristic polynomial, which is |A - λI|, where A is the matrix and I is the identity matrix of the same order. λ is the eigenvalue.

We calculate the characteristic polynomial of T using the definition of T:

|T - λI| = 0=> |((-4 - λ) 4 0) (5 3 - 5) (0 5 - λ)| = 0=> (λ - 23) (λ - 22) (λ - 21) = 0

The eigenvalues of the matrix are 21, 22, and 23.

Corresponding coordinate eigenvectors:

We need to solve the system of equations (T - λI) (v) = 0, where v is the eigenvector of the matrix.

We calculate the eigenvectors for each eigenvalue:

For λ = 21, we have(T - λI) (v) = 0=> ((-25 4 0) (5 -18 5) (0 5 -21)) (v) = 0

We get v = (4, 5, 2).

For λ = 22, we have(T - λI) (v) = 0=> ((-26 4 0) (5 -19 5) (0 5 -22)) (v) = 0

We get v = (4, 5, 2).

For λ = 23, we have(T - λI) (v) = 0=> ((-27 4 0) (5 -20 5) (0 5 -23)) (v) = 0

We get v = (4, 5, 2).

The corresponding coordinate eigenvectors are X1 = (4, 5, 2), X2 = (4, 5, 2), and X3 = (4, 5, 2).

Diagonalizable: We know that if the matrix has n distinct eigenvalues, then it is diagonalizable. In this case, the matrix has three distinct eigenvalues, which means the matrix is diagonalizable.

The eigenvalues of the matrix are λ = 21, 22, 23. There is a sufficient number to guarantee that the matrix is diagonalizable. Therefore, the answer is "Yes."

Answers

To find the volume of the solid generated by revolving the region bounded by the graphs of the equations y = x² + 424 and y = 152x³ about the x-axis  is approximately 2.247 x 10^7 cubic units.

First, let's find the points of intersection between the two curves by setting them equal to each other:

x² + 424 = 152x³

Simplifying the equation, we get:

152x³ - x² - 424 = 0

Unfortunately, solving this equation for x is not straightforward and requires numerical methods or approximations. Once we have the values of x for the points of intersection, let's denote them as x₁ and x₂, with x₁ < x₂.

Next, we can set up the integral to calculate the volume using cylindrical shells. The formula for the volume of a solid generated by revolving a region about the x-axis is:

V = ∫[x₁, x₂] 2πx(f(x) - g(x)) dx

where f(x) and g(x) are the equations of the curves that bound the region. In this case, f(x) = 152x³ and g(x) = x² + 424.

By substituting these values into the integral and evaluating it, we can find the volume of the solid generated by revolving the region bounded by the two curves about the x-axis is approximately 2.247 x 10^7 cubic units.

If (C, A) is observable and T is nonsingular, then (T-¹AT, CT) is observable. That is, observability is invariant under linear coordinate transformations. Proof. The proof is left to Exercise 5.1.

Answers

The observability of a system can be determined in two ways: (a) directly from the definition of the observability matrix, and (b) through duality using Proposition 4.3. Proposition 5.2 states that if (C, A) is observable and T is nonsingular, then (T^(-1)AT, CT) is also observable, demonstrating the invariance of observability under linear coordinate transformations.

To determine the observability of a system, we can use two approaches. The first approach is to directly analyze the observability matrix, which is obtained by stacking the matrices [C, CA, CA^2, ..., CA^(n-1)] and checking for full rank. If the observability matrix has full rank, the system is observable.

The second approach utilizes Proposition 4.3 and Proposition 5.2. Proposition 4.3 states that observability is invariant under linear coordinate transformations. In other words, if (C, A) is observable, then any linear coordinate transformation (T^(-1)AT, CT) will also be observable, given that T is nonsingular.

Proposition 5.2 reinforces the concept by stating that if (C, A) is observable and T is nonsingular, then (T^(-1)AT, CT) is observable as well. This proposition provides a duality-based method for determining observability.

In summary, observability can be assessed by directly examining the observability matrix or by utilizing duality and linear coordinate transformations. Proposition 5.2 confirms that observability remains unchanged under linear coordinate transformations, thereby offering an alternative approach to verifying observability.

Answers

The rate of change of N is inversely proportional to N(x), where N > 0. If N (0) = 6, and N (2) = 9, find N (5). The answer is 12.186.

The rate of change of N is inversely proportional to N(x), which means that the rate of change of N is equal to some constant k divided by N(x). This can be written as dN/dt = k/N(x).

If we integrate both sides of this equation, we get ln(N(x)) = kt + C. If we then take the exponential of both sides, we get N(x) = Ae^(kt), where A is some constant.

We know that N(0) = 6, so we can plug in t = 0 and N(x) = 6 to get A = 6. We also know that N(2) = 9, so we can plug in t = 2 and N(x) = 9 to get k = ln(3)/2.

Now that we know A and k, we can plug them into the equation N(x) = Ae^(kt) to get N(x) = 6e^(ln(3)/2 t).

To find N(5), we plug in t = 5 to get N(5) = 6e^(ln(3)/2 * 5) = 12.186.
