Step-by-step explanation:

If the parent function is y = 2, then the function of the graph would also be y = 2.

The parent function represents the simplest form of a function and serves as a reference for transformations. In this case, the parent function y = 2 is a horizontal line parallel to the x-axis, passing through the y-coordinate 2. Any transformations applied to this parent function would alter its shape or position, but the function itself remains y = 2.

The arc length of the curve y = (1/8) ln (cos(8x)) over the interval [0, π/24] is (√65π) / (192√6).

To find the arc length of the curve y = (1/8) ln (cos(8x)) over the interval [0, π/24], we can use the arc length formula:

L = ∫[a,b] √(1 + (dy/dx)^2) dx

First, let's find the derivative of y with respect to x:

dy/dx = (1/8) * d/dx (ln (cos(8x)))

= (1/8) * (1/cos(8x)) * (-sin(8x)) * 8

= -sin(8x) / (8cos(8x))

Now, we can substitute the derivative into the arc length formula and evaluate the integral:

L = ∫[0, π/24] √(1 + (-sin(8x) / (8cos(8x)))^2) dx

= ∫[0, π/24] √(1 + sin^2(8x) / (64cos^2(8x))) dx

To simplify the expression under the square root, we can use the trigonometric identity: sin^2(θ) + cos^2(θ) = 1.

L = ∫[0, π/24] √(1 + 1/64) dx

= ∫[0, π/24] √(65/64) dx

= (√65/8) ∫[0, π/24] dx

= (√65/8) [x] | [0, π/24]

= (√65/8) * (π/24 - 0)

= (√65π) / (192√6)

Therefore, the arc length of the curve y is (√65π) / (192√6).

To find the component form of the new vector 2a - 36, we first need to find the vector 2a and then subtract 36 from each component.

Given that a = <2, -5>, to find 2a, we multiply each component of a by 2:

2a = 2<2, -5> = <22, 2(-5)> = <4, -10>.

Now, to find 2a - 36, we subtract 36 from each component of 2a:

2a - 36 = <4, -10> - <36, 36> = <4-36, -10-36> = <-32, -46>.

Therefore, the component form of the vector 2a - 36 is <-32, -46>. The resulting vector has components -32 and -46 in the x and y directions, respectively.

By applying the law of sines and solving the given triangle, it is found that the length of side a is approximately 5.45 units.

To solve the triangle, we can use the law of sines, which states that the ratio of the length of a side of a triangle to the sine of its opposite angle is constant for all three sides. Applying the law of sines, we can set up the following proportion:

sin(A)/a = sin(C)/c

Given that A = 90°, B = 60°, C = 50°, and b = 9 units, we can substitute the known values into the equation and solve for side a. Since A = 90°, sin(A) = 1, and sin(C) can be calculated as sin(C) = sin(180° - (A + C)) = sin(30°) = 0.5.

Substituting the values into the equation, we have:

1/a = 0.5/9

Simplifying, we find:

a = 9/0.5 = 18 units.

The resulting integral is ∫[0 to 31621] ∫[0 to 3] e^(u+v)/2 du dv. This integral can be evaluated using standard integration techniques to obtain the numerical result.

To evaluate the integral ∬R e^(x+y) dA over the rectangle R defined by the lines x - y = 0, x + y = 3, x + y = 31621, an appropriate change of variables can be made.

We can simplify the problem by transforming the coordinates using a change of variables.

Let's introduce new variables u and v, defined as u = x + y and v = x - y.

The transformation from (x, y) to (u, v) can be obtained by solving the equations for x and y in terms of u and v. We find that x = (u + v)/2 and y = (u - v)/2.

Next, we need to determine the new region in the (u, v) plane corresponding to the rectangle R in the (x, y) plane. The original lines x - y = 0 and x + y = 3 become v = 0 and u = 3, respectively.

The line x + y = 31621 is transformed into u = 31621. Therefore, the transformed region R' in the (u, v) plane is a triangle defined by the lines v = 0, u = 3, and u = 31621.

Now, we need to calculate the Jacobian of the transformation, which is the determinant of the Jacobian matrix. The Jacobian matrix is given by:

J = |∂x/∂u ∂x/∂v|

|∂y/∂u ∂y/∂v|

Computing the partial derivatives, we find that ∂x/∂u = 1/2, ∂x/∂v = 1/2, ∂y/∂u = 1/2, and ∂y/∂v = -1/2. Therefore, the Jacobian determinant is |J| = (∂x/∂u)(∂y/∂v) - (∂x/∂v)(∂y/∂u) = 1/2.

The integral over the transformed region R' becomes ∬R' e^(u+v) |J| dA' = ∬R' e^(u+v)/2 dA', where dA' is the differential element in the (u, v) plane.

Finally, we evaluate the integral over the triangle R' using the appropriate limits and the transformed variables. The resulting integral is ∫[0 to 31621] ∫[0 to 3] e^(u+v)/2 du dv. This integral can be evaluated using standard integration techniques to obtain the numerical result.

The integral that represents the area of the surface obtained by rotating the given curve about the y-axis is: ∫[0, π/2] 2πy √(1 + (dy/dt)²) dt

To find the area of the surface, we can use the formula for the surface area of revolution, which involves integrating the circumference of each infinitesimally small circle formed by rotating the curve around the y-axis.

The parametric equations x = t cos(t) and y = t sin(t) describe the curve. To calculate the surface area, we need to find the differential arc length element ds:

ds = √(dx² + dy²)

= √((dx/dt)² + (dy/dt)²) dt

= √((-t sin(t) + cos(t))² + (t cos(t) + sin(t))²) dt

a.  The equation of the plane in standard form axt by + cz = d is 0

b.  The component of the unit normal vector for plane Q projected on a unit direction vector for line L is -3/√6.

a) To find the equation of the plane in standard form (ax + by + cz = d), we need to find the normal vector to the plane. Since the plane contains the line L, the direction vector of the line will be parallel to the plane.

The direction vector of line L is given by (-1, 2, -3). To find a normal vector to the plane, we can take the cross product of the direction vector of the line with any vector in the plane. Let's take two points on the plane: P1(1, 1, 2) and P2(0, 3, -1).

Vector between P1 and P2:

P2 - P1 = (0, 3, -1) - (1, 1, 2) = (-1, 2, -3)

Now, we can take the cross product of the direction vector of the line and the vector between P1 and P2:

n = (-1, 2, -3) x (-1, 2, -3)

Using the cross product formula, we get:

n = (2(-3) - 2(-3), -1(-3) - (-1)(-3), -1(2) - 2(-1))

= (-6 + 6, 3 - 3, -2 + 2)

= (0, 0, 0)

The cross product is zero, which means the direction vector of the line and the vector between P1 and P2 are parallel. This implies that the line lies entirely within the plane.

So, the equation of the plane in standard form is:

0x + 0y + 0z = d

0 = d

The equation simplifies to 0 = 0, which is true for all values of x, y, and z. This means that the equation represents the entire 3D space rather than a specific plane.

b. The equation of the plane Q is given as 2x + y + z = 4. To find the component of a unit normal vector for plane Q projected on a unit direction vector for line L, we need to find the dot product between the two vectors.

The direction vector for line L is given by the coefficients of t in the parametric equations, which is (-1, 2, -3).

To find the unit normal vector for plane Q, we can rewrite the equation in the form ax + by + cz = 0, where a, b, and c represent the coefficients of x, y, and z, respectively.

2x + y + z = 4 => 2x + y + z - 4 = 0

The coefficients of x, y, and z in the equation are 2, 1, and 1, respectively. The unit normal vector can be obtained by dividing these coefficients by the magnitude of the vector.

Magnitude of the vector = √(2² + 1² + 1²) = √6

Unit normal vector = (2/√6, 1/√6, 1/√6)

To find the component of this unit normal vector projected on the direction vector of line L, we take their dot product:

Component = (-1)(2/√6) + (2)(1/√6) + (-3)(1/√6)

= -2/√6 + 2/√6 - 3/√6

= -3/√6

Therefore, the component of the unit normal vector for plane Q projected on a unit direction vector for line L is -3/√6.

The power series Σ (n!/(2^n)) from n=0 to infinity represents a series with terms involving factorials and powers of 2. To determine the interval of convergence for this series, we can use the ratio test, which examines the limit of the ratio of consecutive terms as n approaches infinity.

Applying the ratio test, we take the limit as n approaches infinity of the absolute value of the ratio of (n+1)!/(2^(n+1)) divided by n!/(2^n):

lim (n->∞) |((n+1)!/(2^(n+1)))/(n!/(2^n))|

Simplifying this expression, we can cancel out common factors and rewrite it as: lim (n->∞) |(n+1)/(2(n+1))|

Taking the limit, we find: lim (n->∞) |1/2|

The absolute value of 1/2 is simply 1/2, which is less than 1. Therefore, the ratio test tells us that the series converges for all values of x. Since the ratio test guarantees convergence for all x, the interval of convergence for the given power series is (-∞, +∞), meaning it converges for all real numbers.

To apply Green's Theorem, we need to calculate the curl of F, which is given by the partial derivative of the second component of F with respect to x minus the partial derivative of the first component of F with respect to y. Taking the partial derivatives, we find that the curl of F is 2x²y² - y. Now, we evaluate the double integral of the curl of F over the region enclosed by the triangle C.

By setting up the integral and integrating with respect to x and y within the region, we can determine the numerical value of the line integral using Green's Theorem. This method allows us to relate a line integral to a double integral, simplifying the calculation process.

To find the extreme values of the function f(x, y) = 4x + 6y subject to the constraint [tex]x^2 + y^2 = 13[/tex], we can use Lagrange Multipliers.

Lagrange Multipliers is a technique used to find the extreme values of a function subject to one or more constraints. In this case, we have the function f(x, y) = 4x + 6y and the constraint [tex]x^2 + y^2 = 13[/tex].

To apply Lagrange Multipliers, we set up the following system of equations:

1. ∇f = λ∇g, where ∇f and ∇g represent the gradients of the function f and the constraint g, respectively.

2. g(x, y) = 0, which represents the constraint equation.

The gradient of f is given by ∇f = (4, 6), and the gradient of g is ∇g = (2x, 2y).

Setting up the system of equations, we have:

4 = 2λx,

6 = 2λy,

[tex]x^2 + y^2 - 13 = 0[/tex].

Solving these equations simultaneously, we can find the values of x, y, and λ. Substituting these values into the function f(x, y), we can determine the extreme values of the function subject to the given constraint [tex]x^2 + y^2 = 13.[/tex]

The value of (fog)'(1) is (c) 2.

To find (fog)'(1), we need to first determine the composition of the functions f and g. According to the given information, g(z) = 1 - z.

To find f(g(z)), we substitute g(z) into f(x):

f(g(z)) = f(1 - z)

Now, we need to find the derivative of f(g(z)) with respect to z. This can be done using the chain rule:

(fog)'(z) = f'(g(z)) * g'(z)

We have the values of f'(x) for various x and g'(z) = -1. So, let's substitute the values into the formula:

(fog)'(z) = f'(1 - z) * (-1)

We are interested in finding (fog)'(1), so we substitute z = 1:

(fog)'(1) = f'(1 - 1) * (-1) = f'(0) * (-1)

From the given values, we can see that f'(0) = 6. Substituting this value:

(fog)'(1) = 6 * (-1) = -6

Therefore, the value of (fog)'(1) is -6.

The series 2*13 diverges. The sum is DIVERGES. the series 2*13 is an arithmetic series with a common difference of 13. As the terms keep increasing by 13, the series will diverge towards infinity and does not have a finite sum. Therefore, the series is divergent, and its sum is denoted as "DIVERGES."

The given series 2*13 is an arithmetic series with a common difference of 13. This means that each term in the series is obtained by adding 13 to the previous term.

The series starts with 2 and continues as follows: 2, 15, 28, 41, ...

As we can observe, the terms of the series keep increasing by 13. Since there is no upper bound or limit to how large the terms can become, the series will diverge towards infinity. In other words, the terms of the series will keep getting larger and larger without bound, indicating that the series does not have a finite sum.

Therefore, we conclude that the series 2*13 is divergent, and its sum is denoted as "DIVERGES."

The vector projection of vector à onto vector b can be found by taking the dot product of à and the unit vector in the direction of b, and then multiplying it by the unit vector.

To find the vector projection of à onto b, we first need to calculate the unit vector in the direction of b. The unit vector of b is found by dividing b by its magnitude, which is √(2²+0²+1²) = √5.

Next, we calculate the dot product of à and the unit vector of b. The dot product of two vectors is found by multiplying their corresponding components and summing the results. In this case, the dot product is (-1)*(2/√5) + (5)*(0/√5) + (3)*(1/√5) = -2/√5 + 3/√5 = 1/√5.

Finally, we multiply the dot product by the unit vector of b to obtain the vector projection of à onto b. Multiplying 1/√5 by the unit vector (2/√5, 0, 1/√5) gives us (-1/3, 0, -1/3). Thus, the vector projection of à onto b is (-1/3, 0, -1/3).

To determine the coordinates of the points of intersection between the curve y = 4x - x² and the line y = 2x - 3, we can set the two equations equal to each other and solve for x: 4x - x² = 2x - 3

Rearranging the equation, we get:

x² - 2x + 3 = 0

Using the quadratic formula, we find:

x = (2 ± √(2² - 4(1)(3))) / (2(1))

Simplifying further, we have:

x = (2 ± √(-8)) / 2

Since the discriminant (-8) is negative, there are no real solutions for x. Therefore, the line and the curve do not intersect.

(ii) Since the line and the curve do not intersect, there is no enclosed region between them. Hence, the area of the region enclosed by the line and the curve is equal to zero.

We cannot express the vector field (4x + 5y, 3x + 2y, 0) as the sum of a curl-free vector field and a divergence-free vector field, as it does not satisfy the properties of being curl-free or divergence-free.

to express the vector field (4x + 5y, 3x + 2y, 0) as the sum of a curl-free vector field and a divergence-free vector field, we need to find vector fields that satisfy the properties of being curl-free and divergence-free.

a vector field is curl-free if its curl is zero, and it is divergence-free if its divergence is zero.

let's start by finding the curl of the given vector field:

curl(f) = ∇ × f,

where f = (4x + 5y, 3x + 2y, 0).

taking the curl, we have:

curl(f) = (0, 0, ∂(3x + 2y)/∂x - ∂(4x + 5y)/∂y)        = (0, 0, 3 - 5)

       = (0, 0, -2).

since the z-component of the curl is non-zero, the given vector field is not curl-free.

next, let's find the divergence of the given vector field:

divergence(f) = ∇ · f,

where f = (4x + 5y, 3x + 2y, 0).

taking the divergence, we have:

divergence(f) = ∂(4x + 5y)/∂x + ∂(3x + 2y)/∂y + ∂0/∂z

            = 4 + 2             = 6.

since the divergence is non-zero, the given vector field is not divergence-free.

To find the partial derivatives of the function f(x, y) = 3ln(7y - 4[tex]x^2[/tex]), we have the following results: fy = 3 / (7y - 4[tex]x^2[/tex]) and fx = -24x / (7y - 4[tex]x^2[/tex]).

To find the partial derivative with respect to y, fy, we treat x as a constant and differentiate the function with respect to y. The derivative of ln(7y - 4[tex]x^2[/tex]) with respect to y can be found using the chain rule, which states that the derivative of ln(u) with respect to u is 1/u multiplied by the derivative of u with respect to y.

In this case, u = 7y - 4[tex]x^2[/tex], so the derivative of ln(7y - 4[tex]x^2[/tex]) with respect to y is (1/u) * (d(7y - 4[tex]x^2[/tex]) / dy). Simplifying, we get fy = (1 / (7y - 4[tex]x^2[/tex])) * 7 = 3 / (7y - 4[tex]x^2[/tex]).

To find the partial derivative with respect to x, fx, we treat y as a constant and differentiate the function with respect to x. The derivative of ln(7y - 4[tex]x^2[/tex]) with respect to x can be found using the chain rule in a similar manner.

The derivative of ln(7y - 4[tex]x^2[/tex]) with respect to x is (1/u) * (d(7y - 4[tex]x^2[/tex]) / dx). Simplifying, we get fx = (1 / (7y - 4[tex]x^2[/tex])) * (-8x) = -24x / (7y - 4[tex]x^2[/tex]).

Therefore, the partial derivatives are fy = 3 / (7y - 4[tex]x^2[/tex]) and fx = -24x / (7y - 4[tex]x^2[/tex]). These partial derivatives give us the rates of change of the function with respect to y and x, respectively.
