The largest value of a such that cos(x) is decreasing on the interval [0, a],   a = π/2.

To determine the largest value of "a" such that cos(x) is decreasing on the interval [0, a], we need to find the point where the derivative of cos(x) changes from negative to non-negative.

The derivative of cos(x) is given by -sin(x). When cos(x) is decreasing, -sin(x) should be negative. Therefore, we need to find the largest value of "a" such that sin(x) > 0 for all x in the interval [0, a].

The sine function, sin(x), is positive in the interval [0, π/2]. Therefore, the largest value of "a" that satisfies sin(x) > 0 for all x in [0, a] is a = π/2.

Hence, the largest value of "a" such that cos(x) is decreasing on the interval [0, a] is a = π/2.

The equation for the set of points in the xy plane such that the sum of the distances from f(0, 15) and f'(0, -15) is 34 is x² + (y-15)² + x² + (y+15)² = 1156.

Let's consider a point (x, y) on the xy plane. The distance between this point and f(0, 15) can be calculated using the distance formula as √((x-0)² + (y-15)²), and the distance between this point and f'(0, -15) can be calculated as √((x-0)² + (y+15)²). According to the problem, the sum of these distances is 34.

To find the equation for the set of points, we square both sides of the equation and simplify it. Squaring the distances and summing them up, we get ((x-0)² + (y-15)²) + ((x-0)² + (y+15)²) = 34². This simplifies to x² + (y-15)² + x² + (y+15)² = 1156.

Therefore, the equation x² + (y-15)² + x² + (y+15)² = 1156 represents the set of points in the xy plane such that the sum of the distances from f(0, 15) and f'(0, -15) is 34. Any point satisfying this equation will have the property that the sum of its distances from f and f' is equal to 34.

To find a parametric representation for the surface, we need to determine the equation of the plane that passes through the point (0, -1, 6) and contains the vectors (2, 1, 5) and (-7, 2, 6).

To define a plane, we need a point on the plane and two vectors that lie in the plane. In this case, we have the point (0, -1, 6) on the plane and the vectors (2, 1, 5) and (-7, 2, 6) that lie in the plane.

To find the normal vector of the plane, we can take the cross product of the two given vectors. The normal vector is perpendicular to the plane and can be used to define the equation of the plane.

Next, we can use the point-normal form of the equation of a plane, which is given by:

A(x - x_0) + B(y - y_0) + C(z - z_0) = 0,

where (x_0, y_0, z_0) is the given point on the plane, and A, B, and C are the components of the normal vector.

By substituting the values into the equation, we can find the equation of the plane.

Finally, we can write the parametric representation of the surface by expressing x, y, and z in terms of two parameters (usually denoted by u and v) that vary over a certain range. This representation allows us to generate points on the surface by varying the parameters.

In summary, we can find a parametric representation for the surface by first determining the equation of the plane using the given point and vectors. Then, we can express the variables x, y, and z in terms of two parameters (u and v) to obtain the parametric representation of the surface.

To estimate the volume of the solid that lies below the surface z = xy and above the given rectangle, we can use a Riemann sum.

Step 1: Divide the rectangle into smaller subrectangles: We are given a rectangle with dimensions 5 × 16, and we will divide it into smaller subrectangles. Since m = 3 and n = 2, we will divide the length and width of the rectangle into 3 and 2 equal parts, respectively. The length of each subinterval in the x-direction is Δx = (16 - 5)/3 = 11/3, and the width of each subinterval in the y-direction is Δy = 5/2 = 2.5. Step 2: Determine the sample points: For each subrectangle, we need to choose a sample point (xi, yj) to evaluate the function z = xy. Let's choose the sample points at the lower-left corner of each subrectangle. Step 3: Calculate the volume approximation:To estimate the volume, we sum up the volumes of the individual subrectangles. Using the sample points and the dimensions of the subrectangles, the volume of each subrectangle is given by ΔV = Δx * Δy * z, where z = xy.

We can calculate the volume approximation by summing up the volumes of all subrectangles: V ≈ Σ ΔV = Σ Δx * Δy * z. The summation is taken over all the subrectangles, which in this case is from i = 0 to 2 and j = 0 to 1. Step 4: Calculate the volume approximation:  Let's calculate the volume approximation using the Riemann sum. V ≈ Σ Δx * Δy * z

= Σ (11/3) * 2.5 * xy. We need to evaluate xy at each sample point (xi, yj) within the specified ranges. The values of xy for each subrectangle are as follows: (x0, y0) = (5, 10): xy = 5 * 10 = 50

(x1, y0) = (16/3, 10): xy = (16/3) * 10 ≈ 53.33

(x2, y0) = (9, 10): xy = 9 * 10 = 90

(x0, y1) = (5, 5): xy = 5 * 5 = 25

(x1, y1) = (16/3, 5): xy = (16/3) * 5 ≈ 26.67

(x2, y1) = (9, 5): xy = 9 * 5 = 45

Now we can substitute these values into the Riemann sum: V ≈ (11/3)(2.5)(50) + (11/3)(2.5)(53.33) + (11/3)(2.5)(90) + (11/3)(2.5)(25) + (11/3)(2.5)(26.67) + (11/3)(2.5)(45). Simplifying the expression, we can calculate the volume approximation. Please note that this is an approximation, and the actual volume may differ.

The magnitude of the terminal velocity relative to the ground is approximately 60.83 m/s, and the direction is approximately -1.405 radians or -80.36 degrees.

To find the direction and magnitude of the terminal velocity of the parachute relative to the ground, we can consider the vector addition of the wind velocity and the terminal velocity of the parachute.

Let's denote the velocity of the wind as Vw = 10 m/s in the eastward direction (positive x-direction) since the wind is blowing from west to east.

The terminal velocity of the parachute relative to the ground is Vp = 60 m/s in the downward direction (negative y-direction) as it falls vertically.

To find the resultant velocity, we can add these two vectors using vector addition. Since the wind velocity is in the x-direction and the terminal velocity is in the y-direction, the resultant velocity will have both x and y components.

The magnitude of the resultant velocity can be found using the Pythagorean theorem:

|Vr| = √(Vx² + Vy²)

Vx = Vw = 10 m/s (eastward)

Vy = -Vp = -60 m/s (downward)

∴ |Vr| = √((10 m/s)² + (-60 m/s)²)

|Vr| = √(100 + 3600) m/s

|Vr| = √3700 m/s ≈ 60.83 m/s

The direction of the resultant velocity can be found using the arctangent function:

θ = atan(Vy / Vx)

θ = atan((-60 m/s) / (10 m/s))

θ ≈ atan(-6)

Therefore, the direction of the terminal velocity of the parachute relative to the ground is approximately -1.405 radians or -80.36 degrees (measured counterclockwise from the positive x-axis).

True. An exclusion is a value for a variable in the numerator or denominator that will make either the numerator or denominator equal to zero.
True, an exclusion is a value for a variable in the numerator or denominator that will make either the numerator or denominator equal to zero. This is important because division by zero is undefined, and such exclusions must be considered when solving equations or working with fractions. By identifying these exclusions, you can avoid potential mathematical errors and better understand the domain of a function or equation. In mathematical terms, this is known as a "zero denominator" or "zero numerator" situation. In such cases, the equation or expression becomes undefined, and it cannot be evaluated. Therefore, it is essential to identify and exclude such values from the domain of the function or expression to ensure the validity of the result. Failure to do so can lead to incorrect answers or even mathematical errors. Hence, understanding and handling exclusions is an essential aspect of algebra and calculus.

The given function f(x) is discontinuous at x = 3, so the Fourier cosine series might exhibit some oscillations at that point.

To compute the Fourier cosine coefficients for the function f(x) defined as:

f(x) = {1 for 0 < x < 3, -2 for 3 < x < 5}

We'll use the following formulas:

Ao = (1/π) ∫[0, π] f(x) dx

An = (2/π) ∫[0, π] f(x) cos(nπx/L) dx, for n > 0

In this case, L = 5, as the function is periodic with a period of 5.

Calculating Ao:

Ao = (1/π) ∫[0, π] f(x) dx

Since f(x) is piecewise-defined, we need to evaluate the integral over each interval separately:

∫[0, π] f(x) dx = ∫[0, 3] 1 dx + ∫[3, 5] -2 dx

= [x]₀³ + [-2x]₃⁵

= (3 - 0) + (-2(5 - 3))

= 3 - 4

= -1

Therefore, Ao = -1/π.

Calculating An:

An = (2/π) ∫[0, π] f(x) cos(nπx/L) dx

For n > 0, we'll evaluate the integrals over each interval separately:

∫[0, π] f(x) cos(nπx/L) dx = ∫[0, 3] 1 cos(nπx/5) dx + ∫[3, 5] -2 cos(nπx/5) dx

For the interval [0, 3]:

∫[0, 3] 1 cos(nπx/5) dx = (5/π) [sin(nπx/5)]₀³

= (5/π) (sin(3nπ/5) - sin(0))

= (5/π) sin(3nπ/5)

For the interval [3, 5]:

∫[3, 5] -2 cos(nπx/5) dx = (5/π) [-2 sin(nπx/5)]₃⁵

= (5/π) (-2 sin(5nπ/5) + 2 sin(3nπ/5))

= (5/π) (2 sin(3nπ/5) - 2 sin(nπ))

Therefore, An = (5/π) (sin(3nπ/5) - sin(nπ)) for n > 0.

Calculating the specific values:

Ao = -1/π

An = (5/π) (sin(3nπ/5) - sin(nπ))

To find the values of the Fourier cosine series C(x) at specific points:

C(5) = Ao/2 = -1/(2π)

C(-4) = Ao/2 = -1/(2π)

C(6) = Ao/2 = -1/(2π)

To find the minimum value of the function f(x, y) = x² + y² subject to the constraint xy = 15, we can use the method of Lagrange multipliers.

Let's define the Lagrangian function L(x, y, λ) as L(x, y, λ) = f(x, y) - λ(xy - To find the minimum value, we need to solve the following system of equations:

∂L/∂x = 2x - λy = 0

∂L/∂y = 2y - λx = 0

∂L/∂λ = xy - 15 = 0

From the first equation, we get x = (λy)/2. Substituting this into the second equation gives y - (λ²y)/2 = 0, which simplifies to y(2 - λ²) = 0. This gives us two possibilities: y = 0 or λ² = 2.

If y = 0, then from the third equation we have x = ±√15. Plugging these values into f(x, y) = x² + y², we find that f(√15, 0) = 15 and f(-√15, 0) = 15.

If λ² = 2, then from the first equation we have x = ±√30/λ and from the third equation we have y = ±√30/λ. Plugging these values into f(x, y) = x² + y², we find that f(√30/λ, √30/λ) = 2λ²/λ² + 2λ²/λ² = 4.

The given equation is y = 8/(x^2 + 1). It has no x-intercepts, a y-intercept at (0, 8), no x-axis symmetry, no y-axis symmetry, and no origin symmetry.

1. X-Intercepts: X-intercepts occur when y equals zero. In this case, setting y = 0 and solving for x results in an equation of x^2 + 1 = 0, which has no real solutions. Therefore, the equation y = 8/(x^2 + 1) does not have any x-intercepts.

2. Y-Intercept: The y-intercept is the point where the graph intersects the y-axis. When x equals zero, the equation becomes y = 8/(0^2 + 1) = 8/1 = 8. Hence, the y-intercept is at (0, 8).

3. X-Axis Symmetry: X-axis symmetry occurs when the graph remains unchanged when reflected across the x-axis. In this case, the graph does not possess x-axis symmetry because if you reflect the graph across the x-axis, the resulting graph will be different.

To find the line of intersection between two planes, we need to solve the system of equations formed by equating the two planes. We have the following two equations:

-6x - y - z = -20 ...(1)

5x + y - 2z = -112 ...(2)

To eliminate y, we can add equations (1) and (2) together, which gives us:

-6x - y - z + 5x + y - 2z = -20 - 112

Simplifying this equation, we get:

-x - 3z = -132 ...(3)

To eliminate x, we can multiply equation (2) by 6 and equation (1) by 5, and then subtract equation (1) from equation (2). This yields:

30x + 6y - 12z - 30x - 5y - 5z = -672 - (-100)

Simplifying this equation, we get:

y - 7z = -572 ...(4)

Now, we have equations (3) and (4) with two variables x and y eliminated. To solve this system, we can express x and y in terms of a parameter t. Let's choose z as the parameter.

From equation (3), we have:

x = -132 + 3z ...(5)

From equation (4), we have:

y = -572 + 7z ...(6)

Now, we can substitute equations (5) and (6) into either equation (1) or (2) to solve for z. Let's substitute them into equation (1):

-6(-132 + 3z) - (-572 + 7z) - z = -20

Simplifying this equation, we get:

-14z = -122

Dividing both sides by -14, we obtain:

z = -22

Substituting this value of z back into equations (5) and (6), we find:

x = -14

y = -10

Therefore, the equation for the line of intersection between the two planes is:

x = -14

y = -10 - 3t

z = -22 + 2t

Let's verify each equation:

1. (sin x + cos x)^2 = sin 2x + 1

Expanding the left side of the equation, we get sin^2 x + 2sin x cos x + cos^2 x. Using the trigonometric identity sin^2 x + cos^2 x = 1, we can simplify the left side to 1 + 2sin x cos x. By applying the double angle identity sin 2x = 2sin x cos x, we can rewrite the right side as 2sin x cos x + 1. Therefore, both sides of the equation are equal, confirming it as an identity.

2. sec 2x = 2 + sec^2 x - sec^4 x

To verify this equation, we'll examine its components. The left side involves the secant function, while the right side has a combination of constants and secant functions raised to powers. These components do not match, and therefore the equation is not an identity.

3. (cos 2x + sin 2x)^2 = 1 + sin 4x (cos 2x - sin 2x)

Expanding the left side of the equation, we have cos^2 2x + 2cos 2x sin 2x + sin^2 2x. By using the Pythagorean identity cos^2 2x + sin^2 2x = 1, we can simplify the left side to 1 + 2cos 2x sin 2x. On the right side, we have sin 4x (cos 2x - sin 2x). Applying double angle identities and simplifying further, we obtain sin 4x (2cos^2 x - 2sin^2 x). By using the double angle identity sin 4x = 2sin 2x cos 2x, the right side simplifies to 2sin 2x cos 2x. Hence, both sides of the equation are equal, confirming it as an identity.

By applying Green's theorem, we can convert the line integral into a double integral over the region enclosed by the circle. The first paragraph will summarize the final result of the line integral, and the second paragraph will provide an explanation of the steps involved in obtaining that result.

Paragraph 1: The line integral of F along the circle of radius a, centered at the origin and traversed counterclockwise, is equal to 2πa^2(30 + 3242). This means that the value of the line integral depends only on the radius of the circle and the constant terms in the vector field.

Paragraph 2: To evaluate the line integral, we can use Green's theorem, which relates a line integral around a closed curve to a double integral over the region enclosed by the curve. Applying Green's theorem to our vector field F, we can convert the line integral into a double integral of the curl of F over the region enclosed by the circle. Since the curl of F is zero everywhere except at the origin, the only contribution to the double integral comes from the origin. By evaluating the double integral, we find that the line integral is equal to 2πa^2 times the sum of the constant terms in the vector field, which is (30 + 3242).

By using mathematical induction, we can prove that the sequence {a_n} defined as a_1 = 1 and a_n+1 = 1/2 a_n + 1 for each n in the set of natural numbers, satisfies the inequality a_n ≤ 2 for all n.

First, we establish the base case. When n = 1, we have a_1 = 1, which is less than or equal to 2.

Now, let's assume that the inequality holds for some arbitrary value k, i.e., a_k ≤ 2. We need to show that this implies the inequality holds for the next term, a_k+1.

Using the recursive definition of the sequence, we have a_k+1 = 1/2 a_k + 1. Since a_k ≤ 2 (our induction hypothesis), we can substitute this into the equation to get a_k+1 ≤ 1/2 * 2 + 1, which simplifies to a_k+1 ≤ 2.

Therefore, if the inequality holds for a_k, it also holds for a_k+1. By the principle of mathematical induction, we can conclude that a_n ≤ 2 for all n in the set of natural numbers.

In this case, the function [tex]f(x) = (x - 1)(x - 5)(x - 6)[/tex] is continuous on the closed interval (4, 6], as it is a polynomial function and polynomials are continuous everywhere. However, the function is not differentiable at x = 5 because it has a point of non-differentiability (a vertical tangent) at x = 5.

Since f(x) fails to meet the condition of differentiability on the open interval (4, 6), Rolle's Theorem cannot be applied to this function on the interval (4, 6].

To evaluate c'(2), we need to use the chain rule.

The chain rule states that if c(x) = f(g(x)), then the derivative of c(x) with respect to x, denoted as c'(x), is given by c'(x) = f'(g(x)) * g'(x).

From the given table, we can see the values of f(x), g(x), f'(x), and g'(x) for different values of x. We need to find the values at x = 2 to evaluate c'(2).

Let's denote f(x) = f, g(x) = g, f'(x) = f', and g'(x) = g' for simplicity.

From the table:

f(2) = -1

g(2) = 0

f'(2) = -4

g'(2) = 2

Now, we can evaluate c'(2) using the chain rule:

c'(2) = f'(g(2)) * g'(2)

     = f'(0) * 2

From the table, we don't have the value of f'(0) directly, but we can find it using the values of f'(x) and g(x) from the table.

Since g(2) = 0, we can find the corresponding value of x from the table, which is x = 4. Therefore, f'(0) = f'(4).

From the table:

f(4) = -4

g(4) = -2

f'(4) = 3

g'(4) = 1

Now we have the value of f'(0) = f'(4) = 3.

Substituting this into the expression for c'(2):

c'(2) = f'(g(2)) * g'(2)

     = f'(0) * 2

     = 3 * 2

     = 6

Therefore, c'(2) = 6.

a.The derivatives using implicit differentiation for the given equations is y' = (5 - e^(xy) - dx * d/dx (e^(xy))) / 4

b. The derivatives using implicit differentiation for the given equations is  2px + 2 - (5 - e^(xy) - dx * d/dx (e^(xy))) * y

To find the derivatives using implicit differentiation for the given equations, let's proceed step by step:

a. For the equation dx * e^(xy) = 5x + 4y + 9:

Take the derivative of both sides with respect to x:

d/dx (dx * e^(xy)) = d/dx (5x + 4y + 9)

Simplify the left side using the product rule:

d/dx (dx) * e^(xy) + dx * d/dx (e^(xy)) = 5 + 4y' + 0

Since dx/dx = 1, the first term simplifies to e^(xy):

e^(xy) + dx * d/dx (e^(xy)) = 5 + 4y'

Now, isolate y' by rearranging the equation:

4y' = 5 - e^(xy) - dx * d/dx (e^(xy))

Finally, divide by 4 to solve for y':

y' = (5 - e^(xy) - dx * d/dx (e^(xy))) / 4

b. For the equation d²y/dx² + y² = px² + 2x:

Take the derivative of both sides with respect to x:

d/dx (d²y/dx² + y²) = d/dx (px² + 2x)

Apply the chain rule to the first term:

d²y/dx² + 2y * dy/dx = 2px + 2

Simplify the equation:

d²y/dx² + 2y * dy/dx = 2px + 2 - 2y * dy/dx

Rearrange the equation to solve for d²y/dx²:

d²y/dx² = 2px + 2 - 2y * dy/dx - 2y * dy/dx

= 2px + 2 - 4y * dy/dx

Note that dy/dx can be replaced using the previous equation:

dy/dx = (5 - e^(xy) - dx * d/dx (e^(xy))) / 4

Substitute dy/dx into the equation:

d²y/dx² = 2px + 2 - 4y * ((5 - e^(xy) - dx * d/dx (e^(xy))) / 4)

= 2px + 2 - (5 - e^(xy) - dx * d/dx (e^(xy))) * y

These are the derivatives obtained through implicit differentiation for the given equations.

The reparametrized curve r(t(s)) is given by r(t(s)) = (4 + s)i + (2 - 3s/5)j + 0k. To reparametrize the curve r(t) in terms of arclength, we need to find the parameter t(s) that represents the distance along the curve.

By calculating the magnitude of the velocity vector, we can determine the speed of the curve. Then, we integrate the speed function to find the arclength parameter. The velocity vector of the curve r(t) = (4 + t)i + (2 - 3t)j + 0k is given by the derivative with respect to t:

v(t) = i - 3j.

To find the speed of the curve, we calculate the magnitude of the velocity vector:

|v(t)| = sqrt(1 + (-3)^2) = sqrt(10).

The speed of the curve is constant and equal to sqrt(10). To find the arclength parameter s, we integrate the speed function with respect to t:

s = ∫sqrt(10) dt = sqrt(10)t + C.

Since we want the arclength to start from 0, we set C = 0. Solving for t, we have:

t = s/sqrt(10).

Now we can reparametrize the curve r(t) in terms of arclength:

r(t(s)) = (4 + t(s))i + (2 - 3t(s)/5)j + 0k

= (4 + s/sqrt(10))i + (2 - 3s/(5sqrt(10)))j + 0k.

Therefore, the reparametrized curve in terms of arclength is given by r(t(s)) = (4 + s)i + (2 - 3s/5)j + 0k.

To find the volume of the solid of revolution when the first quadrant region bounded by y = 4 - x, y = x, and x = 4 is rotated about different lines, we can use the method of cylindrical shells.

(i) Rotating about the line y = -2:

In this case, the line y = -2 is located below the region bounded by the curves. The resulting solid of revolution will have a hole in the center. To find the volume, we integrate the circumference of each cylindrical shell multiplied by its height.

The height of each shell is given by the difference between the upper and lower curves: (4 - x) - (-2) = 6 - x.

The radius of each shell is the distance from the line y = -2 to the axis of rotation, which is x + 2.

Integrating the volume formula, we have:

V = ∫[x=0 to x=4] 2π(x + 2)(6 - x) dx

Simplifying and integrating, we get:

V = ∫[x=0 to x=4] (12πx - 2πx²) dx

V = [6πx² - (2/3)πx³] evaluated from x = 0 to x = 4

V = 6π(4²) - (2/3)π(4³) - (0 - 0)

V = 96π - (128/3)π

V = (288 - 128)π/3

V = (160/3)π cubic units

Therefore, the volume of the solid of revolution when the region is rotated about y = -2 is (160/3)π cubic units.

(ii) Rotating about the line x = 5:

In this case, the line x = 5 is located to the right of the region bounded by the curves. The resulting solid of revolution will have a cylindrical shape. Again, we integrate the circumference of each cylindrical shell multiplied by its height.

The height of each shell is given by the difference between the rightmost boundary x = 4 and the leftmost boundary x = 5, which is 4 - 5 = -1. However, since the height cannot be negative, we take the absolute value: |(-1)| = 1.

The radius of each shell is the distance from the line x = 5 to the axis of rotation, which is 5 - x.

Integrating the volume formula, we have:

V = ∫[x=0 to x=4] 2π(5 - x)(1) dx

Simplifying and integrating, we get:

V = ∫[x=0 to x=4] 2π(5 - x) dx

V = [2π(5x - (1/2)x²)] evaluated from x = 0 to x = 4

V = 2π(5(4) - (1/2)(4²)) - 2π(5(0) - (1/2)(0²))

V = 2π(20 - 8) - 2π(0 - 0)

V = 24π

Therefore, the volume of the solid of revolution when the region is rotated about x = 5 is 24π cubic units.

In summary:

(i) When rotated about y = -2, the volume is (160/3)π cubic units.

(ii) When rotated about x = 5, the volume is 24π cubic units.

The z-score for the value 75, with a mean of 74 and a standard deviation of 5, is 0.20.

The z-score measures the number of standard deviations a particular value is away from the mean.

It is calculated using the formula: z = (x - μ) / σ, where x is the value, μ is the mean, and σ is the standard deviation.

In this case, the value is 75, the mean is 74, and the standard deviation is 5.

Plugging these values into the formula, we get: z = (75 - 74) / 5 = 0.20.

The positive value of the z-score indicates that the value of 75 is 0.20 standard deviations above the mean.

Since the standard deviation is 5, we can interpret this as 75 being 1 unit (0.20 × 5) above the mean.

The z-score is a useful measure as it allows us to compare values from different distributions and determine their relative positions.

It also helps in understanding the significance of a particular value in relation to the distribution it belongs to.

we cannot find a minimum of the function f(x, y) = 1 + 11y subject to the constraint x - y = 18 using the method of Lagrange multipliers.

To find the minimum of the function f(x, y) = 1 + 11y subject to the constraint x - y = 18 using the method of Lagrange multipliers, we need to set up the following system of equations:

1. ∇f(x, y) = λ∇g(x, y)

2. g(x, y) = 0

where ∇f(x, y) and ∇g(x, y) are the gradients of the functions f and g, respectively, and λ is the Lagrange multiplier.

Let's begin by calculating the gradients of f(x, y) and g(x, y):

∇f(x, y) = (∂f/∂x, ∂f/∂y) = (0, 11)

∇g(x, y) = (∂g/∂x, ∂g/∂y) = (1, -1)

Setting up the system of equations:

1. (0, 11) = λ(1, -1)

2. x - y = 18

From equation 1, we have two equations:

0 = λ   ... (3)

11 = -λ   ... (4)

Since λ cannot be both 0 and -11 simultaneously, we can conclude that there is no solution for λ that satisfies both equations.

To determine if a vector field F = (P, Q, R) is conservative, we need to check if its components have continuous partial derivatives and satisfy the condition ∇ × F = 0, where ∇ is the gradient operator.

Let's analyze the vector field,

[tex]F(x, y, z) = 3y^2z^2i + 16xyzj + 24xy^2z^2k:[/tex]

Checking the partial derivatives:

∂P/∂y = [tex]6yz^2[/tex], ∂Q/∂x = 16yz, ∂Q/∂y = 16xz, ∂R/∂y = [tex]48xyz^2[/tex], ∂R/∂z = [tex]48xy^2z[/tex]

The partial derivatives exist and are continuous for all components.

Calculating the curl (∇ × F):

∇ × F = (∂R/∂y - ∂Q/∂z)i - (∂R/∂x - ∂P/∂z)j + (∂Q/∂x - ∂P/∂y)k

[tex]= (48xyz^2 - 0)i - (0 - 16xz)j + (16yz - 6yz^2)k\\= 48xyz^2i + 16xzj + (16yz - 6yz^2)k[/tex]

The curl is not zero, as it contains nonzero terms.

Therefore, ∇ × F ≠ 0.

Since the curl of F is not zero, F is not a conservative vector field.

To evaluate the limit of the function (x³ + y²)/(x² + y²) as (x, y) approaches (0, 0), we can use the Squeeze Theorem. By examining the function along different paths approaching the origin, we can determine that the limit is equal to 0.

Let's consider two paths: the x-axis (y = 0) and the y-axis (x = 0). Along the x-axis, the function simplifies to x³/x² = x. As x approaches 0, the function approaches 0. Along the y-axis, the function simplifies to y²/y² = 1. As y approaches 0, the function remains constant at 1.

Since the function is bounded between x and 1 along these two paths, and both x and 1 approach 0 as (x, y) approaches (0, 0), we can conclude that the limit of (x³ + y²)/(x² + y²) as (x, y) approaches (0, 0) is 0.

In conclusion, by considering the behavior of the function along different paths, we can determine that the limit of (x³ + y²)/(x² + y²) as (x, y) approaches (0, 0) is 0 using the Squeeze Theorem.

The gradient of f at the point (-3, 4) is (∂f/∂x, ∂f/∂y) = (1/2√(-3), 1). (b) The equation of the tangent plane at the point (-3,4) is  z = (1/2√(-3))(x + 3) + y (c) Unit vector is (√3/√13, √12/√13).

(a) The gradient of f at the point (-3, 4) can be found by taking the partial derivatives with respect to x and y:

∇f(-3, 4) = (∂f/∂x, ∂f/∂y) = (∂(4 + √x + y)/∂x, ∂(4 + √x + y)/∂y)

Evaluating the partial derivatives, we have:

∂f/∂x = 1/2√x

∂f/∂y = 1

So, the gradient of f at (-3, 4) is (∂f/∂x, ∂f/∂y) = (1/2√(-3), 1).

(b) To determine the equation of the tangent plane at the point (-3, 4), we use the formula:

z - z0 = ∇f(a, b) · (x - x0, y - y0)

Plugging in the values, we have:

z - 4 = (1/2√(-3), 1) · (x + 3, y - 4)

Expanding the dot product, we get:

z - 4 = (1/2√(-3))(x + 3) + (y - 4)

Simplifying further, we have:

z = (1/2√(-3))(x + 3) + y

(c) To find the unit vector in the direction of steepest ascent of f at (-3, 4), we use the normalized gradient vector:

∇f/||∇f|| = (∂f/∂x, ∂f/∂y)/||(∂f/∂x, ∂f/∂y)||

Calculating the norm of the gradient vector, we have:

||(∂f/∂x, ∂f/∂y)|| = ||(1/2√(-3), 1)|| = √[(1/4(-3)) + 1] = √(1/12 + 1) = √(13/12)

Thus, the unit vector in the direction of steepest ascent of f at (-3, 4) is:

∇f/||∇f|| = ((1/2√(-3))/√(13/12), 1/√(13/12)) = (√3/√13, √12/√13).
