To diagonalize matrix A, we need to find an orthogonal matrix P. Given that the characteristic polynomial of A is X(X - 9)² and the vector [1 -6] is an eigenvector.

The given characteristic polynomial X(X - 9)² tells us that the eigenvalues of matrix A are 0, 9, and 9. We are also given that the vector [1 -6] is an eigenvector of A. To diagonalize A, we need to find two more eigenvectors corresponding to the eigenvalue 9.

Let's find the remaining eigenvectors:

For the eigenvalue 0, we solve the equation (A - 0I)v = 0, where I is the identity matrix and v is the eigenvector. Solving this equation, we find v₁ = [2 -1 1]ᵀ.

For the eigenvalue 9, we solve the equation (A - 9I)v = 0. Solving this equation, we find v₂ = [1 2 2]ᵀ and v₃ = [1 0 1]ᵀ.

Next, we normalize the eigenvectors to obtain the orthogonal matrix P:

P = [v₁/norm(v₁) v₂/norm(v₂) v₃/norm(v₃)]

  = [2√6/3 -√6/3 √6/3; √6/3 2√6/3 0; √6/3 2√6/3 √6/3]

Now, we can verify that PAP is diagonal:

PAPᵀ = [2√6/3 -√6/3 √6/3; √6/3 2√6/3 0; √6/3 2√6/3 √6/3]

      × [5 -2 8; -2 4 -2; 5 -2 5]

      × [2√6/3 √6/3 √6/3; -√6/3 2√6/3 2√6/3; √6/3 0 √6/3]

    = [0 0 0; 0 9 0; 0 0 9]

As we can see, PAPᵀ is a diagonal matrix, confirming that P diagonalizes matrix A.

The given differential equation is x³y" + 2x²y' + xy' - y = 0. We need to find the general solution for this differential equation.

To find the general solution, we can use the method of power series or assume a solution of the form y = ∑(n=0 to ∞) anxn, where an are coefficients to be determined.

First, we find the derivatives of y with respect to x:

y' = ∑(n=1 to ∞) nanxn-1,

y" = ∑(n=2 to ∞) n(n-1)anxn-2.

Substituting these derivatives into the differential equation, we have:

x³(∑(n=2 to ∞) n(n-1)anxn-2) + 2x²(∑(n=1 to ∞) nanxn-1) + x(∑(n=0 to ∞) nanxn) - (∑(n=0 to ∞) anxn) = 0.

Simplifying and re-arranging terms, we get:

∑(n=2 to ∞) n(n-1)anxn + 2∑(n=1 to ∞) nanxn + ∑(n=0 to ∞) nanxn - ∑(n=0 to ∞) anxn = 0.

Now, we equate the coefficients of like powers of x to obtain a recursion relation for the coefficients an.

For n = 0: -a₀ = 0, which gives a₀ = 0.

For n = 1: 2a₁ - a₁ = 0, which gives a₁ = 0.

For n ≥ 2: n(n-1)an + 2nan + nan - an = 0, which simplifies to: (n² + 2n + 1 - 1)an = 0.

Solving the above equation, we have: an = 0 for n ≥ 2.

Therefore, the general solution of the given differential equation is:

y(x) = a₀ + a₁x.

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.

No, you are not maximizing your utility. To determine if utility is maximized, you need to compare the marginal rate of substitution (MRS) to the price ratio (Px/Py). In this case, the MRS is 4, but the price ratio is 4/2 = 2. Since MRS is not equal to the price ratio, you can improve your utility by adjusting your consumption.

To determine if you are maximizing your utility, you need to compare the marginal rate of substitution (MRS) to the price ratio (Px/Py). The MRS measures the amount of one good that a consumer is willing to give up to obtain an additional unit of the other good while keeping utility constant.

In this case, the MRS is given as 4, which means you are willing to give up 4 units of Good Y to obtain an additional unit of Good X while maintaining the same level of utility. However, the price ratio is Px/Py = $4/$2 = 2.

To maximize utility, the MRS should be equal to the price ratio. In this case, the MRS is higher than the price ratio, indicating that you value Good X more than the market price suggests. Therefore, you should consume less of Good X and more of Good Y to reach the point where the MRS is equal to the price ratio.

Since the MRS is 4 and the price ratio is 2, it implies that you are purchasing too much of Good X relative to Good Y. By decreasing your consumption of Good X and increasing your consumption of Good Y, you can align the MRS with the price ratio and achieve utility maximization.

The statement P(-3/2) is invalid since n must be an integer greater than or equal to zero. As a result, our mathematical induction is complete.

For each of integers n ≥ 0, let P(n) be the statement n × 2² = n × 2^(n+2) + 2.(a)

i. Writing P(0).When n = 0, we have:

P(0) is equivalent to 0 × 2² = 0 × 2^(0+2) + 2.

This reduces to: 0 = 2, which is not true.

ii. Determining whether P(0) is true.

The answer is no.

(b) Writing P(k). For some k ≥ 0, we have:

P(k): k × 2²

= k × 2^(k+2) + 2.

(c) Writing P(k+1).

Now, we have:

P(k+1): (k+1) × 2²

= (k+1) × 2^(k+1+2) + 2.

(d) Show by mathematical induction that P(n) is true. By mathematical induction, we must now demonstrate that P(n) is accurate for all n ≥ 0.

We have previously discovered that P(0) is incorrect. As a result, we begin our mathematical induction with n = 1. Since n = 1, we have:

P(1): 1 × 2² = 1 × 2^(1+2) + 2.This becomes 4 = 4 + 2, which is valid.

Inductive step:

Assume that P(n) is accurate for some n ≥ 1 (for an arbitrary but fixed value). In this way, we want to demonstrate that P(n+1) is also true. Now we must demonstrate:

P(n+1): (n+1) × 2² = (n+1) × 2^(n+3) + 2.

We will begin with the left-hand side (LHS) to show that this is true.

LHS = (n+1) × 2² [since we are considering P(n+1)]LHS = (n+1) × 4 [since 2² = 4]

LHS = 4n+4

We will now begin on the right-hand side (RHS).

RHS = (n+1) × 2^(n+3) + 2 [since we are considering P(n+1)]

RHS = (n+1) × 8 + 2 [since 2^(n+3) = 8]

RHS = 8n+10

The equation LHS = RHS is what we want to accomplish.

LHS = RHS implies that:

4n+4 = 8n+10

Subtracting 4n from both sides, we obtain:

4 = 4n+10

Subtracting 10 from both sides, we get:

-6 = 4n

Dividing both sides by 4, we find

-3/2 = n.

The statement P(-3/2) is invalid since n must be an integer greater than or equal to zero. As a result, our mathematical induction is complete. The mathematical induction proof is complete, demonstrating that P(n) is accurate for all n ≥ 0.

The derivative of the function `y = 3x + 2x + x - 5` is `6x - 5`. This can be found using the sum rule, the power rule, and the constant rule of differentiation.

The sum rule states that the derivative of a sum of two functions is the sum of the derivatives of the two functions. In this case, the function `y` is the sum of three functions: `3x`, `2x`, and `x`. The derivatives of these three functions are `3`, `2`, and `1`, respectively. Therefore, the derivative of `y` is `3 + 2 + 1 = 6`.

The power rule states that the derivative of `x^n` is `n * x^(n - 1)`. In this case, the function `y` contains the terms `3x`, `2x`, and `x`. The exponents of these terms are `1`, `1`, and `0`, respectively. Therefore, the derivatives of these three terms are `3`, `2`, and `0`, respectively.

The constant rule states that the derivative of a constant is zero. In this case, the function `y` contains the constant term `-5`. Therefore, the derivative of this term is `0`.

Combining the results of the sum rule, the power rule, and the constant rule, we get that the derivative of `y` is `6x - 5`.

The expression for the distance of the liquid surface from the top of the cone (d) in terms of the height of the liquid (h) is:

d = (R / H) * h

To find an expression for the distance of the liquid surface from the top of the cone, let's consider the geometry of the inverted cone.

We can start by defining some variables:

R: the radius of the base of the cone

H: the height of the cone

h: the height of the liquid inside the cone (measured from the tip of the cone)

Now, we need to determine the relationship between the variables R, H, h, and d (the distance of the liquid surface from the top of the cone).

First, let's consider the similar triangles formed by the original cone and the liquid-filled cone. By comparing the corresponding sides, we have:

(R - d) / R = (H - h) / H

Now, let's solve for d:

(R - d) / R = (H - h) / H

Cross-multiplying:

R - d = (R / H) * (H - h)

Expanding:

R - d = (R / H) * H - (R / H) * h

R - d = R - (R / H) * h

R - R = - (R / H) * h + d

0 = - (R / H) * h + d

R / H * h = d

Finally, we can express d in terms of h:

d = (R / H) * h

Therefore, the expression for the distance of the liquid surface from the top of the cone (d) in terms of the height of the liquid (h) is:

d = (R / H) * h

Answer:

From the limit expression √29+h-√29 lim h-0 h, we can simplify the numerator as:

√(29+h) - √29 = (√(29+h) - √29)(√(29+h) + √29)/(√(29+h) + √29)

= (29+h - 29)/(√(29+h) + √29)

= h/(√(29+h) + √29)

Thus the limit expression becomes:

lim h->0 h/(√(29+h) + √29)

To simplify this expression further, we can multiply the numerator and denominator by the conjugate of the denominator, which is (√(29+h) - √29):

lim h->0 h/(√(29+h) + √29) * (√(29+h) - √29)/(√(29+h) - √29)

= lim h->0 h(√(29+h) - √29)/((29+h) - 29)

= lim h->0 (√(29+h) - √29)/h

This is now in the form of a derivative, specifically the derivative of f(x) = √x evaluated at x = 29. Therefore, we can take f(x) = √x and a = 29, and the limit is the slope of the tangent line to the curve y = √x at x = 29.

To determine the value of the limit, we can use the definition of the derivative:

f'(29) = lim h->0 (f(29+h) - f(29))/h = lim h->0 (√(29+h) - √29)/h

This is the same limit expression we derived earlier. Therefore, f(x) = √x and a = 29, and the limit is f'(29) = lim h->0 (√(29+h) - √29)/h.

To calculate the limit, we can plug in h = 0 and simplify:

lim h->0 (√(29+h) - √29)/h

= lim h->0 ((√(29+h) - √29)/(h))(1/1)

= f'(29)

= 1/(2√29)

Thus, the function f(x) = √x and the number a = 29, and the limit is 1/(2√29).

(a) The cost function can be formed by adding the fixed costs to the variable costs per unit multiplied by the number of units produced. Let's denote the variable cost per unit as 'c' and the number of units produced as 'x'. The cost function would be: Cost(x) = 30,800 + c*x.

The revenue function can be formed by multiplying the selling price per unit by the number of units sold. Since the selling price is given as $1,572, the revenue function would be: Revenue(x) = 1,572*x.

To find the break-even points, we need to determine the values of 'x' for which the cost equals the revenue. In other words, we need to solve the equation: Cost(x) = Revenue(x).

(b) To find the vertex of the revenue function, we need to determine the maximum point on the revenue curve. Since the revenue function is a linear function with a positive slope, the vertex occurs at the highest value of 'x'. In this case, there is no maximum point as the revenue function is a straight line with an increasing slope.

To find the vertex of the profit function, we need to subtract the cost function from the revenue function. The profit function is given by: Profit(x) = Revenue(x) - Cost(x).

To identify the maximum profit, we need to find the highest point on the profit curve. This can be done by determining the vertex of the profit function, which corresponds to the maximum profit.

Now, differentiating L(t) w.r.t t, we get:

v(t) = L'(t) = a + 2bt

Also, given that,

v(0) = 100 km/h

Substituting t = 0,

we get: v(0) = a = 100 km/h

Also, it is given that v(t) = 10 km/h at some time t.

Therefore, we can write:

v(t) = a + 2bt = 10 km/h

Substituting the value of a,

we get:

10 km/h = 100 km/h + 2bt2

bt = -90 km/h

b = -45 km/h²

As b is negative, the car is decelerating.

Now, substituting the value of b in the expression for v(t),

we get: v(t) = 100 - 45t km/h At t = ? (the moment when the speed of the car becomes 10 km/h),

we have: v(?) = 10 km/h100 - 45t = 10 km/h

t = 1.8 h

The tax intercept, the vertical asymptote of the graph of y, and the slope of the line tangent to the curve of y at the point t = 0 is t= a. We also found an expression for y' for ln(x¹) = 3* dx.

The given expression is y = ln(4 - at) - 1, where a is a positive constant.

The tax intercept is at t = a

We can find tax intercept by substituting t = a in the given expression.

y = ln(4 - at) - 1

y = ln(4 - aa) - 1

y = ln(4 - a²) - 1

Since a is a positive constant, the expression (4 - a²) will always be positive.

The vertical asymptote of the graph of y is at t = a. The vertical asymptote occurs when the denominator becomes 0. Here the denominator is (4 - at).

We know that if a function f(x) has a vertical asymptote at x = a, then f(x) can be written as

f(x) = g(x) / (x - a)

Here g(x) is a non-zero and finite function as in the given expression

y = ln(4 - at) - 1,

g(x) = ln(4 - at).

If it exists, we need to find the limit of the function g(x) as x approaches a.

Limit of g(x) = ln(4 - at) as x approaches

a,= ln(4 - a*a)= ln(4 - a²).

So the vertical asymptote of the graph of y is at t = a.

The slope m of the line tangent to the curve of y at the point t = 0 is m = a

To find the slope of the line tangent to the curve of y at the point t = 0, we need to find the first derivative of

y.y = ln(4 - at) - 1

dy/dt = -a/(4 - at)

For t = 0,

dy/dt = -a/4

The slope of the line tangent to the curve of y at the point t = 0 is -a/4

The given expression is ln(x^1) = 3x.

ln(x) = 3x

Now, differentiating both sides concerning x,

d/dx (ln(x)) = d/dx (3x)

(1/x) = 3

Simplifying, we get

y' = 3

The security level function is the minimum expected payoff that a player would receive given a certain mixed strategy and the assumption that the other player would select his or her worst response to this strategy. In a zero-sum game, the security level function of one player is equal to the negation of the security level function of the other player. In this game, player Alice has matrix A while player Bob has matrix B which is the negative of matrix A.

In order to determine the security level function for Alice and Bob, we need to find the maximin and minimax values of their respective matrices. Here, Alice's maximin value is 3 and her minimax value is 1. On the other hand, Bob's maximin value is -3 and his minimax value is -1.

Therefore, the security level function of Alice is given by

s_A(p_B) = max(x_1 + 5x_2, 3x_1 + 10x_2)

where x_1 and x_2 are the probabilities that Bob assigns to his two pure strategies.

Similarly, the security level function of Bob is given by

s_B(p_A) = min(-x_1 - 7x_2, -x_1 - 8x_2, -4x_1 + x_2, -2x_1 - 3x_2).

A saddle point in a zero-sum game is a cell in the matrix that is both a minimum for its row and a maximum for its column. In this game, the cell (2,1) has the value 3 which is both the maximum for row 2 and the minimum for column 1. Therefore, the strategy (2,1) is a saddle point of the game. If Alice plays strategy 2 with probability 1 and Bob plays strategy 1 with probability 1, then the expected payoff for Alice is 3 and the expected payoff for Bob is -3.

Therefore, the value of the game is 3 and this is achieved at the saddle point (2,1). To show that this saddle point is a Nash equilibrium, we need to show that neither player has an incentive to deviate from this strategy. If Alice deviates from strategy 2, then she will play either strategy 1 or strategy 3. If she plays strategy 1, then Bob can play strategy 2 with probability 1 and his expected payoff will be 5 which is greater than -3. If she plays strategy 3, then Bob can play strategy 1 with probability 1 and his expected payoff will be 4 which is also greater than -3. Therefore, Alice has no incentive to deviate from strategy 2. Similarly, if Bob deviates from strategy 1, then he will play either strategy 2, strategy 3, or strategy 4. If he plays strategy 2, then Alice can play strategy 1 with probability 1 and her expected payoff will be 5 which is greater than 3. If he plays strategy 3, then Alice can play strategy 2 with probability 1 and her expected payoff will be 10 which is also greater than 3. If he plays strategy 4, then Alice can play strategy 2 with probability 1 and her expected payoff will be 10 which is greater than 3. Therefore, Bob has no incentive to deviate from strategy 1. Therefore, the saddle point (2,1) is a Nash equilibrium.

In summary, we have determined the security level function for Alice and Bob in a zero-sum game given by the matrix -3 5 3 10 A = 7 8 4 5 4 -1 2 3 for player Alice and the matrix B= -A for the player Bob.

The value of a₀ in the numerator of the Laplace transform F(s) = L{f(t)} is 480.

By applying the Laplace transform to both sides of the integral equation, we obtain:

L{f(t)} - 32L{e^{-9t}} = 15tL{sen(t-u)f(u)du}

The Laplace transform of [tex]e^{-9t}[/tex] is given by[tex]L{e^{-9t}} = 1/(s+9)[/tex], and the Laplace transform of sen(t-u)f(u)du can be represented by F(s), which has a numerator of the form (a₂s² + a₁s + a₀)(s² + 1).

Comparing the equation, we have:

1/(s+9) - 32/(s+9) = 15tF(s)

Combining the terms on the left side, we get:

(1 - 32/(s+9))/(s+9) = 15tF(s)

To find the value of a₀, we compare the numerators:

1 - 32/(s+9) = 15t(a₂s² + a₁s + a₀)

Expanding the equation, we have:

s² + 9s - 32 = 15ta₂s² + 15ta₁s + 15ta₀

By comparing the coefficients of the corresponding powers of s, we get:

a₂ = 15t

a₁ = 0

a₀ = -32

Therefore, the value of a₀ is -32.

we can use the formula Q(t) = Q_max * (1 - e^(-t/tau)). The limiting charge is equal to the maximum charge the capacitor can reach, Q_max.

In a series circuit consisting of a capacitor, resistor, and inductor, with a 24-volt battery connected, we need to determine the charge on the capacitor at different time intervals. Given the values of the components (capacitor: 0.25 x 10 F, resistor: 5 x 10¹² Ω, inductor: 1 H) and the initial charge on the capacitor being zero, we can calculate the charge at specific time points and the limiting charge.

To calculate the charge on the capacitor at a given time, we can use the formula for charging a capacitor in an RL circuit. The equation is given by Q(t) = Q_max * (1 - e^(-t / tau)), where Q(t) is the charge at time t, Q_max is the maximum charge the capacitor can reach, tau is the time constant (tau = L / R), and e is the base of the natural logarithm.

Substituting the given values, we can calculate the time constant tau as 1 H / 5 x 10¹² Ω. We can then calculate the charge on the capacitor at specific time intervals, such as 0.001 seconds and 0.01 seconds, by plugging in the respective values of t into the formula.

Additionally, to determine the limiting charge, we need to consider that as time goes to infinity, the charge on the capacitor approaches its maximum value, Q_max. Therefore, the limiting charge is equal to Q_max.

The first derivative of the given function is 2 - sin(x). And, the value of f '(1) is 1.15853.

Given function is f(x) = 2x+cos(x). We must find the first derivative of f(x) and then f '(1). To find f '(x), we use the derivative formulas of composite functions, which are as follows:

If y = f(u) and u = g(x), then the chain rule says that y = f(g(x)), then

dy/dx = dy/du × du/dx.

Then,

f(x) = 2x + cos(x)

df(x)/dx = d/dx (2x) + d/dx (cos(x))

df(x)/dx = 2 - sin(x)

So, f '(x) = 2 - sin(x)

Now,

f '(1) = 2 - sin(1)

f '(1) = 2 - 0.84147

Therefore, the slope of the line tangent to the curve of the function y = f(x) = x² at point P(2, 4) is 4 + h, where h represents a small change in x.

To find the slope of a line tangent to the curve of the function y = f(x) = x² at a specific point P(x₁, y₁), we can use the equation m = (f(x₁ + h) - f(x₁)) / h, where h represents a small change in x.

In this case, we want to find the slope at point P(2, 4). Substituting the values into the equation, we have m = (f(2 + h) - f(2)) / h. Let's calculate the values needed to find the slope.

First, we need to find f(2 + h) and f(2). Since f(x) = x², we have f(2 + h) = (2 + h)² and f(2) = 2² = 4.

Expanding (2 + h)², we get f(2 + h) = (2 + h)(2 + h) = 4 + 4h + h².

Now we can substitute the values back into the slope equation: m = (4 + 4h + h² - 4) / h.

Simplifying the expression, we have m = (4h + h²) / h.

Canceling out the h term, we are left with m = 4 + h.

Therefore, the slope of the line tangent to the curve of the function y = f(x) = x² at point P(2, 4) is 4 + h, where h represents a small change in x.

To find the volume generated by rotating the region bounded by the curves y = 3x and y = 0 about the line x = 4, we can use the method of cylindrical shells. The volume V is equal to the integral of the cylindrical shells formed by the region.

To calculate the volume using cylindrical shells, we need to integrate the area of each shell. The radius of each shell is the distance from the axis of rotation (x = 4) to the curve y = 3x, which is given by r = 4 - x. The height of each shell is the difference between the y-values of the curves y = 3x and y = 0, which is h = 3x.

We need to determine the limits of integration for x. From the given curves, we can see that the region is bounded by x = 2 (the point of intersection between the curves) and x = 0 (the y-axis).

The volume of each cylindrical shell can be calculated as dV = 2πrh*dx, where dx is an infinitesimally small width element along the x-axis. Therefore, the total volume V is given by the integral of dV from x = 0 to x = 2:

V = ∫[from 0 to 2] 2π(4 - x)(3x) dx

Evaluating this integral will give us the volume V generated by rotating the region about x = 4.

The average value of a function f(x) on an interval [a, b] is given by the formula:

f_avg = (1/(b-a)) * ∫[a,b] f(x) dx

In this case, we want to find the average value of f(x) = xsec²(x²) on the interval [0,2]. So we can compute it as:

f_avg = (1/(2-0)) * ∫[0,2] xsec²(x²) dx

To solve the integral, we can make a substitution. Let u = x², then du/dx = 2x, and dx = du/(2x). Substituting these expressions in the integral, we have:

f_avg = (1/2) * ∫[0,2] (1/(2x))sec²(u) du

The integral ∫ f(x - 1) √(√x + 1)dx can be simplified to 2 (√b + √a) ∫ f(x)dx - 4 ∫ (x + 1) * f(x)dx.

To solve the integral ∫ f(x - 1) √(√x + 1)dx, we can use the substitution method. Let's consider u = √x + 1. Then, u² = x + 1 and x = u² - 1. Now, differentiate both sides with respect to x, and we get du/dx = 1/(2√x) = 1/(2u)dx = 2udu.

We can use these values to replace x and dx in the integral. Let's see how it's done:

∫ f(x - 1) √(√x + 1)dx

= ∫ f(u² - 2) u * 2udu

= 2 ∫ u * f(u² - 2) du

Now, we need to solve the integral ∫ u * f(u² - 2) du. We can use integration by parts. Let's consider u = u and dv = f(u² - 2)du. Then, du/dx = 2udx and v = ∫f(u² - 2)dx.

We can write the integral as:

∫ u * f(u² - 2) du

= uv - ∫ v * du/dx * dx

= u ∫f(u² - 2)dx - 2 ∫ u² * f(u² - 2)du

Now, we can solve this integral by putting the limits and finding the values of u and v using substitution. Then, we can substitute the values to find the final answer.

The value of the integral is now in terms of u and f(u² - 2). To find the answer, we need to replace u with √x + 1 and substitute the value of x in the integral limits.

The final answer is given by:

∫ f(x - 1) √(√x + 1)dx

= 2 ∫ u * f(u² - 2) du

= 2 [u ∫f(u² - 2)dx - 2 ∫ u² * f(u² - 2)du]

= 2 [(√x + 1) ∫f(x)dx - 2 ∫ (x + 1) * f(x)dx], where u = √x + 1. The limits of the integral are from √a + 1 to √b + 1.

Now, we can substitute the values of limits to get the answer. The final answer is:

∫ f(x - 1) √(√x + 1)dx

= 2 [(√b + 1) ∫f(x)dx - 2 ∫ (x + 1) * f(x)dx] - 2 [(√a + 1) ∫f(x)dx - 2 ∫ (x + 1) * f(x)dx]

It will take approximately 2.303tc seconds for the capacitor to reach a 90% charge.

A) To determine the constant "a" for the capacitor to eventually attain a charge of 2000 µF (microfarads) as t approaches infinity, we set a equal to the capacitance value C, which is 2000 µF. Hence, the value of "a" is 2000 µF.

B) If it takes 12 s to reach a 50% charge (i.e., 1000 µF), we can determine the time constant "tc" using the formula Q(t) = a(1 − e^(-t/tc)).

When t equals tc, Q(tc) = a(1 − e^(-1)) = 0.63a.

We are given that Q(tc) = 0.5a. So, we have 0.5a = a(1 − e^(-1)).

Simplifying this equation, we find that tc = 12 s.

C) To find the time it takes for the capacitor to reach a 90% charge (i.e., 1800 µF), we need to solve for t in the equation Q(t) = 0.9a = 0.9 × 2000 = 1800 µF.

Using the formula Q(t) = a(1 − e^(-t/tc)), we have 0.9a = a(1 − e^(-t/tc)).

This simplifies to e^(-t/tc) = 0.1.

Taking the natural logarithm of both sides, we get -t/tc = ln(0.1).

Solving for t, we have t = tc ln(10) ≈ 2.303tc.

Thus, it will take approximately 2.303tc seconds for the capacitor to reach a 90% charge.
