State the characteristic properties of the Brownian motion.

Given vector function is

F = (5z +5x4) i¯+ (3y + 6z + 6 sin(y4)) j¯+ (5x + 6y + 3e²¹) k

(a) Curl of F is given by

The curl of F is curl

F = [tex](6cos(y^4))i + 5j + 4xi - (6cos(y^4))i - 6k[/tex]

= 4xi - 6k

(b) The answer to part (a) tells that the J.C. of F is zero over any loop in [tex]R^3[/tex].

(c) If C1 is any closed curve in[tex]R^3[/tex], then ∫C1 F. dr = 0.

(d) Given Cl is the half-circle

[tex](x - 20)^2 + (y - 35)^2[/tex] = 1, y > 35.

It is traversed from (21, 35) to (19, 35).

To find the line integral of F over Cl, we use Green's theorem.

We know that,

∫C1 F. dr = ∫∫S (curl F) . dS

Where S is the region enclosed by C1 in the xy-plane.

C1 is made up of a half-circle with a line segment joining its endpoints.

We can take two different loops S1 and S2 as shown below:

Here, S1 and S2 are two loops whose boundaries are C1.

We need to find the line integral of F over C1 by using Green's theorem.

From Green's theorem, we have,

∫C1 F. dr = ∫∫S1 (curl F) . dS - ∫∫S2 (curl F) . dS

Now, we need to find the surface integral of (curl F) over the two surfaces S1 and S2.

We can take S1 to be the region enclosed by the half-circle and the x-axis.

Similarly, we can take S2 to be the region enclosed by the half-circle and the line x = 20.

We know that the normal to S1 is -k and the normal to S2 is k.

Thus,∫∫S1 (curl F) .

dS = ∫∫S1 -6k . dS

= -6∫∫S1 dS

= -6(π/2)

= -3π

Similarly,∫∫S2 (curl F) . dS = 3π

Thus,

∫C1 F. dr = ∫∫S1 (curl F) . dS - ∫∫S2 (curl F) . dS

= -3π - 3π

= -6π

Therefore, J.C. of F over the half-circle is -6π.

a. The functions f(x) = (x - 2) and g(x) = (x + 3) do not intersect or have any zeros. b. The graphs of f(x) = (x - 2) and g(x) = (x + 3) are parallel lines.         c. There are no intervals where f(x) > g(x), but g(x) > f(x) for all intervals.       d. The domain and range of both functions, f(x) and g(x), are all real numbers.

a. To find the point of intersection or zeros, we set f(x) equal to g(x) and solve for x:

f(x) = g(x)

(x - 2) = (x + 3)

Simplifying the equation, we get:

x - 2 = x + 3

-2 = 3

This equation has no solution. Therefore, the two functions do not intersect.

b. We can sketch the graphs of the two functions on the same set of axes to visualize their behavior. The function f(x) = (x - 2) is a linear function with a slope of 1 and y-intercept of -2. The function g(x) = x + 3 is also a linear function with a slope of 1 and y-intercept of 3. Since the two functions do not intersect, their graphs will be parallel lines.

c. To find the intervals for when f(x) > g(x) and g(x) > f(x), we can compare the expressions of f(x) and g(x):

f(x) = (x - 2)

g(x) = (x + 3)

To determine when f(x) > g(x), we can set up the inequality:

(x - 2) > (x + 3)

Simplifying the inequality, we get:

x - 2 > x + 3

-2 > 3

This inequality is not true for any value of x. Therefore, there is no interval where f(x) is greater than g(x).

Similarly, to find when g(x) > f(x), we set up the inequality:

(x + 3) > (x - 2)

Simplifying the inequality, we get:

x + 3 > x - 2

3 > -2

This inequality is true for all values of x. Therefore, g(x) is greater than f(x) for all intervals.

d. The domain of both functions, f(x) and g(x), is the set of all real numbers since there are no restrictions on x in the given functions. The range of f(x) is also all real numbers since the function is a straight line that extends infinitely in both directions. Similarly, the range of g(x) is all real numbers because it is also a straight line with infinite extension.

Given,

A: Set of student-athletes: Set of students who like to watch basketball: Set of students who have completed the  Calculus III course.

We have to describe the sets An (BUC) and (An B)UC. Then we have to find which set would be bigger. An (BUC) is the intersection of A and the union of B and C. This means that the elements of An (BUC) will be the student-athletes who like to watch basketball, have completed the Calculus III course, or both.

So, An (BUC) = A ∩ (B ∪ C)

Now, let's find (An B)UC.

(An B)UC is the complement of the intersection of A and B concerning the universal set U. This means that (An B)UC consists of all the students who are not both student-athletes and students who like to watch basketball.

So,

(An B)UC = U – (A ∩ B)

Let's now see which set is bigger. First, we need to find the size of An (BUC). This is the size of the intersection of A with the union of B and C. Let's assume that the size of A, B, and C are a, b, and c, respectively. The size of BUC will be the size of the union of B and C,

b + c – bc/a.

The size of An (BUC) will be the size of the intersection of A with the union of B and C, which is

= a(b + c – bc)/a

= b + c – bc.

The size of (An B)UC will be the size of U minus the size of the intersection of A and B. Let's assume that the size of A, B, and their intersection is a, b, and x, respectively.

The size of (An B) will be the size of A plus the size of B minus the size of their intersection, which is a + b – x. The size of (An B)UC will be the size of U minus the size of (An B), which is (a + b – x) - (a + b - x)/a(bc). So, the bigger set depends on the specific sizes of A, B, and C.

The value of x is 7/3, which can be rounded to two decimal places as approximately 2.33.

To solve the equation 2x + 8 + 4x = 22, we need to combine like terms and isolate the variable x.

Combining like terms, we have:

6x + 8 = 22

Next, we want to isolate the term with x by subtracting 8 from both sides of the equation:

6x + 8 - 8 = 22 - 8

6x = 14

To solve for x, we divide both sides of the equation by 6:

(6x) / 6 = 14 / 6

x = 14/6

Simplifying the fraction 14/6, we get:

x = 7/3

a) The probability of a successful well in field A is 18%.
b) The probability of a successful well in field B is 16.5%.
c) The probability of both a successful well in field A and a successful well in field B is 7.2%.
d) The probability of at least one successful well in the two fields together is 26.7%.

To calculate the probabilities, we use the given information and apply the rules of conditional probability and probability addition.
a) The probability of a successful well in field A is calculated by multiplying the probability of drilling a well in field A (40%) with the probability of success given that a well is drilled in field A (45%). Therefore, the probability of a successful well in field A is 0.4 * 0.45 = 0.18 or 18%.
b) Similarly, the probability of a successful well in field B is calculated by multiplying the probability of drilling a well in field B (30%) with the probability of success given that a well is drilled in field B (55%). Hence, the probability of a successful well in field B is 0.3 * 0.55 = 0.165 or 16.5%.
c) To find the probability of both a successful well in field A and a successful well in field B, we multiply the probabilities of success in each field. Therefore, the probability is 0.18 * 0.165 = 0.0297 or 2.97%.
d) The probability of at least one successful well in the two fields together can be calculated by adding the probabilities of a successful well in field A and a successful well in field B, and subtracting the probability of both wells being unsuccessful (complement). Thus, the probability is 0.18 + 0.165 - 0.0297 = 0.315 or 31.5%.

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:

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.

i) To find T(I), we substitute A = I (the identity matrix) into the definition of T:

T(I) = B^(-1)IB = B^(-1)B = I

To find T(B), we substitute A = B into the definition of T:

T(B) = B^(-1)BB = B^(-1)B = I

ii) To show that I is a linear transformation, we need to verify two properties: additivity and scalar multiplication.

Additivity:

Let A, C be matrices in MM, and consider T(A + C):

T(A + C) = B^(-1)(A + C)B

Expanding this expression using matrix multiplication, we have:

T(A + C) = B^(-1)AB + B^(-1)CB

Now, consider T(A) + T(C):

T(A) + T(C) = B^(-1)AB + B^(-1)CB

Since matrix multiplication is associative, we have:

T(A + C) = T(A) + T(C)

Thus, T(A + C) = T(A) + T(C), satisfying the additivity property.

Scalar Multiplication:

Let A be a matrix in MM and let k be a scalar, consider T(kA):

T(kA) = B^(-1)(kA)B

Expanding this expression using matrix multiplication, we have:

T(kA) = kB^(-1)AB

Now, consider kT(A):

kT(A) = kB^(-1)AB

Since matrix multiplication is associative, we have:

T(kA) = kT(A)

Thus, T(kA) = kT(A), satisfying the scalar multiplication property.

Since T satisfies both additivity and scalar multiplication, we conclude that I is a linear transformation.

iii) To show that ker(T) = {0}, we need to show that the only matrix A in MM such that T(A) = 0 is the zero matrix.

Let A be a matrix in MM such that T(A) = 0:

T(A) = B^(-1)AB = 0

Since B^(-1) is invertible, we can multiply both sides by B to obtain:

AB = 0

Since A and B are invertible matrices, the only matrix that satisfies AB = 0 is the zero matrix.

Therefore, the kernel of T, ker(T), contains only the zero matrix, i.e., ker(T) = {0}.

iv) To show that if CE Man n, then C € R(T), we need to show that if C is in the column space of T, then there exists a matrix A in MM such that T(A) = C.

Since C is in the column space of T, there exists a matrix A' in MM such that T(A') = C.

Let A = BA' (Note: A is in MM since B and A' are in MM).

Now, consider T(A):

T(A) = B^(-1)AB = B^(-1)(BA')B = B^(-1)B(A'B) = A'

Thus, T(A) = A', which means T(A) = C.

Therefore, if C is in the column space of T, there exists a matrix A in MM such that T(A) = C, satisfying C € R(T).

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. We have also determined a saddle point of the zero-sum game and showed that this saddle point is a Nash equilibrium.

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.

The given question is to prove the following statements using induction,

where,

(a) n ∑ i =1(i2 − 1) = (n)(2n2+3n−5)/6 , for all n ≥ 1

(b) 1 + 4 + 7 + 10 + ... + (3n − 2) = n(3n−1)/2 , for any positive integer n ≥ 1

(c) 13n − 1 is a multiple of 12 for n ∈ N (where N is the set of all natural numbers)

(d) 1 + 3 + 5 + ... + (2n − 1) = n2 for all n ≥ 1

Let's prove each statement using mathematical induction as follows:

a) Proof of n ∑ i =1(i2 − 1) = (n)(2n2+3n−5)/6 , for all n ≥ 1 using induction statement:

Base Step:

For n = 1,

the left-hand side (LHS) is 12 – 1 = 0,

and the right-hand side ,(RHS) is (1)(2(12) + 3(1) – 5)/6 = 0.

Hence the statement is true for n = 1.

Assumption:

Suppose that the statement is true for some arbitrary natural number k. That is,n ∑ i =1(i2 − 1) = (k)(2k2+3k−5)/6

InductionStep:

Let's prove the statement is true for n = k + 1,

which is given ask + 1 ∑ i =1(i2 − 1)

We can write this as [(k+1) ∑ i =1(i2 − 1)] + [(k+1)2 – 1]

Now we use the assumption and simplify this expression to get,

(k + 1) ∑ i =1(i2 − 1) = (k)(2k2+3k−5)/6 + [(k+1)2 – 1]

This simplifies to,

(k + 1) ∑ i =1(i2 − 1) = (2k3 + 9k2 + 13k + 6)/6 + [(k2 + 2k)]

This can be simplified as

(k + 1) ∑ i =1(i2 − 1) = (k + 1)(2k2 + 5k + 3)/6

which is the same as

(k + 1)(2(k + 1)2 + 3(k + 1) − 5)/6

Therefore, the statement is true for all n ≥ 1 using induction.

b) Proof of 1 + 4 + 7 + 10 + ... + (3n − 2) = n(3n−1)/2, for any positive integer n ≥ 1 using induction statement:

Base Step:

For n = 1, the left-hand side (LHS) is 1,

and the right-hand side (RHS) is (1(3(1) − 1))/2 = 1.

Hence the statement is true for n = 1.

Assumption:

Assume that the statement is true for some arbitrary natural number k. That is,1 + 4 + 7 + 10 + ... + (3k − 2) = k(3k − 1)/2

Induction Step:

Let's prove the statement is true for n = k + 1,

which is given ask + 1(3k + 1)2This can be simplified as(k + 1)(3k + 1)2 + 3(k + 1) – 5)/2

We can simplify this further(k + 1)(3k + 1)2 + 3(k + 1) – 5)/2 = [(3k2 + 7k + 4)/2] + (3k + 2)

Hence,(k + 1) (3k + 1)2 + 3(k + 1) − 5 = [(3k2 + 10k + 8) + 6k + 4]/2 = (k + 1) (3k + 2)/2

Therefore, the statement is true for all n ≥ 1 using induction.

c) Proof of 13n − 1 is a multiple of 12 for n ∈ N (where N is the set of all natural numbers) using induction statement:

Base Step:

For n = 1, the left-hand side (LHS) is 13(1) – 1 = 12,

which is a multiple of 12. Hence the statement is true for n = 1.

Assumption:

Assume that the statement is true for some arbitrary natural number k. That is, 13k – 1 is a multiple of 12.

Induction Step:

Let's prove the statement is true for n = k + 1,

which is given ask + 1.13(k+1)−1 = 13k + 12We know that 13k – 1 is a multiple of 12 using the assumption.

Hence, 13(k+1)−1 is a multiple of 12.

Therefore, the statement is true for all n ∈ N.

Base Step:

For n = 1, the left-hand side (LHS) is 1

the right-hand side (RHS) is 12 = 1.

Hence the statement is true for n = 1.

Assumption: Assume that the statement is true for some arbitrary natural number k.

That is,1 + 3 + 5 + ... + (2k − 1) = k2

Induction Step:

Let's prove the statement is true for n = k + 1, which is given as

k + 1.1 + 3 + 5 + ... + (2k − 1) + (2(k+1) − 1) = k2 + 2k + 1 = (k+1)2

Therefore, the function f(x) = 7√(7x-3) is increasing on the interval (1, 5) based on the definition of an increasing function.

To determine if the function f(x) = 7√(7x-3) is increasing or decreasing, we will use the definition of an increasing and decreasing function.

A function is said to be increasing on an interval if, for any two points x₁ and x₂ in that interval where x₁ < x₂, the value of f(x₁) is less than or equal to f(x₂).

Similarly, a function is said to be decreasing on an interval if, for any two points x₁ and x₂ in that interval where x₁ < x₂, the value of f(x₁) is greater than or equal to f(x₂).

Let's apply this definition to the given function f(x) = 7√(7x-3):

To determine if the function is increasing or decreasing, we need to compare the values of f(x) at two different points within the domain of the function.

Let's choose two points, x₁ and x₂, where x₁ < x₂:

For x₁ = 1 and x₂ = 5:

f(x₁) = 7√(7(1) - 3) = 7√(7 - 3) = 7√4 = 7(2) = 14

f(x₂) = 7√(7(5) - 3) = 7√(35 - 3) = 7√32

Since 1 < 5 and f(x₁) = 14 is less than f(x₂) = 7√32, we can conclude that the function is increasing on the interval (1, 5).

Therefore, the function f(x) = 7√(7x-3) is increasing on the interval (1, 5) based on the definition of an increasing function.

The coordinates of point B on line segment AC are (8/13, 17/26).

To find the coordinates of point B on line segment AC, we need to use the given ratio of 2:12:12.

Calculate the difference in x-coordinates and y-coordinates between points A and C.
  - Difference in x-coordinates: -4 - 2 = -6
  - Difference in y-coordinates: 7 - (-8) = 15

Divide the difference in x-coordinates and y-coordinates by the sum of the ratios (2 + 12 + 12 = 26) to find the individual ratios.
  - x-ratio: -6 / 26 = -3 / 13
  - y-ratio: 15 / 26

Multiply the individual ratios by the corresponding ratio values to find the coordinates of point B.
  - x-coordinate of B: (2 - 3/13 * 6) = (2 - 18/13) = (26/13 - 18/13) = 8/13
  - y-coordinate of B: (-8 + 15/26 * 15) = (-8 + 225/26) = (-208/26 + 225/26) = 17/26

The integral we need to evaluate is:[tex]∫∫Dy^(1/3) (x^7+1)dxdy[/tex]; D is the area of integration bounded by y=L(u) and y=u. Thus the final result is: Ans:[tex]2/27(∫(u=2 to u=L^-1(41)) (u^2/3 - 64)du + ∫(u=L^-1(41) to u=27) (64 - u^2/3)du)[/tex]

We shall use the idea of interchanging the order of integration. Since the curve L(u) is the same as x=2u^3/27, we have x^(1/3) = 2u/3. Thus we can express D in terms of u and v where u is the variable of integration.

As shown below:[tex]∫∫Dy^(1/3) (x^7+1)dxdy = ∫(u=2 to u=L^-1(41))∫(v=8 to v=u^(1/3))y^(1/3) (x^7+1)dxdy + ∫(u=L^-1(41) to u=27)∫(v=8 to v=27^(1/3))y^(1/3) (x^7+1)dxdy[/tex]

Now for a fixed u between 2 and L^-1(41),

we have the following relationship among the variables x, y, and u: 2u^3/27 ≤ x ≤ u^(1/3); 8 ≤ y ≤ u^(1/3)

Solving for x, we have x = y^3.

Thus, using x = y^3, the integral becomes [tex]∫(u=2 to u=L^-1(41))∫(v=8 to v=u^(1/3))y^(1/3) (y^21+1)dydx = ∫(u=2 to u=L^-1(41))∫(v=8 to v=u^(1/3))y^(22/3) + y^(1/3)dydx[/tex]

Integrating w.r.t. y first, we have [tex]2u/27[ (u^(7/3) + 2^22/3) - (u^(7/3) + 8^22/3)] = 2u/27[(2^22/3) - (u^(7/3) + 8^22/3)] = 2(u^2/3 - 64)/81[/tex]

Now for a fixed u between L⁻¹(41) and 27,

we have the following relationship among the variables x, y, and u:[tex]2u^3/27 ≤ x ≤ 27; 8 ≤ y ≤ 27^(1/3)[/tex]

Solving for x, we have x = y³.

Thus, using x = y^3, the integral becomes [tex]∫(u=L^-1(41) to u=27)∫(v=8 to v=27^(1/3))y^(1/3) (y^21+1)dydx = ∫(u=L^-1(41) to u=27)∫(v=8 to v=27^(1/3))y^(22/3) + y^(1/3)dydx[/tex]

Integrating w.r.t. y first, we have [tex](u^(7/3) - 2^22/3) - (u^(7/3) - 8^22/3) = 2(64 - u^2/3)/81[/tex]

Therefore, the correct option is A.

To solve the given polynomial equation, let's rearrange it to set it equal to zero:

2x³ - x² - 32x + 16 = 0

Now, we can factor out the common factors from each pair of terms:

x²(2x - 1) - 16(2x - 1) = 0

Notice that we have a common factor of (2x - 1) in both terms. We can factor it out:

(2x - 1)(x² - 16) = 0

Now, we have a product of two factors equal to zero. According to the zero-product principle, if a product of factors is equal to zero, then at least one of the factors must be zero.

Therefore, we set each factor equal to zero and solve for x:

Setting the first factor equal to zero:

2x - 1 = 0

2x = 1

x = 1/2

Setting the second factor equal to zero:

x² - 16 = 0

(x + 4)(x - 4) = 0

Setting each factor equal to zero separately:

x + 4 = 0 ⇒ x = -4

x - 4 = 0 ⇒ x = 4
