The distance between the point (-2, 8, 1) and the line of intersection between the two planes is sqrt(82/3) or approximately 5.15 units.

To compute the distance between a point and a line in 3D space, we can use the formula derived from vector projections.

First, we need to find a vector that lies on the line of intersection between the two planes. To do this, we can solve the system of equations formed by the two plane equations:

X + y + z = 3

5x + 2y + 32 = 8

By solving this system, we find that x = -1, y = 2, and z = 2. So, a point on the line of intersection is (-1, 2, 2), and a vector in the direction of the line is given by the coefficients of x, y, and z in the plane equations, which are (1, 1, -1).

Next, we find a vector connecting the given point (-2, 8, 1) to the point on the line of intersection. This vector is given by (-2 – (-1), 8 – 2, 1 – 2) = (-1, 6, -1).

To calculate the distance, we project the connecting vector onto the direction vector of the line. The distance is the magnitude of the component of the connecting vector that is perpendicular to the line. Using the formula:

Distance = |(connecting vector) – (projection of connecting vector onto line direction)|

We obtain:

Distance = |(-1, 6, -1) – [(1, 1, -1) dot (-1, 6, -1)]/(1^2 + 1^2 + (-1)^2)(1, 1, -1)|

         = |(-1, 6, -1) – (4)/(3)(1, 1, -1)|

         = |(-1, 6, -1) – (4/3)(1, 1, -1)|

         = |(-1, 6, -1) – (4/3, 4/3, -4/3)|

         = |(-1 – 4/3, 6 – 4/3, -1 + 4/3)|

         = |(-7/3, 14/3, -1/3)|

         = sqrt[(-7/3)^2 + (14/3)^2 + (-1/3)^2]

         = sqrt[49/9 + 196/9 + 1/9]

         = sqrt[246/9]

According to baseball rules, a regulation ball must weigh between 142 and 149 grams. The acceptable weight limits, in grams, for a regulation ball are determined by the specified weight range in ounces.
Baseball rules specify that a regulation ball shall weigh no less than 5.00 ounces nor more than 5.25 ounces. To convert these limits to grams, you can use the conversion factor of 1 ounce = 28.3495 grams. The acceptable lower limit for a regulation ball is 5.00 ounces * 28.3495 = 141.7475 grams, and the upper limit is 5.25 ounces * 28.3495 = 148.83475 grams. Therefore, the acceptable limits, in grams, for a regulation baseball are approximately 141.75 grams to 148.83 grams. This weight range ensures that all baseballs used in games are consistent and fair for both teams. It is important for players, coaches, and umpires to adhere to these regulations in order to maintain the integrity of the game. Any ball that falls outside of the acceptable weight range should not be used in official games or practices.

To express the area under the curve y = x³ from 0 to 1 as a limit using the definition of the area with right endpoints, we divide the interval [0, 1] into n subintervals of equal width Δx. Then, we evaluate the function at the right endpoint of each subinterval and multiply it by Δx to obtain the area of each approximating rectangle. Taking the sum of these areas gives us the Riemann sum. By taking the limit as n approaches infinity, we can express the area under the curve as a limit.

We start by dividing the interval [0, 1] into n subintervals of equal width Δx = 1/n. The right endpoint of each subinterval is given by xi = iΔx, where i ranges from 1 to n. We evaluate the function at these right endpoints and multiply by Δx to get the area of each rectangle:

Ai = f(xi)Δx = f(iΔx)Δx = (iΔx)³Δx = i³(Δx)⁴.

The total area, denoted as Rn, is obtained by summing up the areas of all the rectangles:

Rn = Σ Ai = Σ i³(Δx)⁴.

Next, we take the limit as n approaches infinity to express the area under the curve as a limit:

A = lim (Rn) = lim Σ i³(Δx)⁴.

To evaluate this limit, we can use the formula for the sum of cubes of the first n integers:

1³ + 2³ + 3³ + ... + n³ = (n(n + 1)/2)².

In our case, we have Σ i³ = (n(n + 1)/2)². Substituting this into the limit expression, we get:

A = lim Σ i³(Δx)⁴ = lim [(n(n + 1)/2)²(Δx)⁴] = lim [(n(n + 1)/2)²(1/n)⁴].

Taking the limit as n approaches infinity, we simplify the expression and find the value of the area under the curve.

The volume generated when the given area is revolved about the y-axis is approximately 21.333π cubic units.

To find the volume generated when the given area in the first quadrant is revolved about the y-axis, we can use the method of cylindrical shells.

The given area is bounded by the parabolic curve x^2 = 8y, the line x = 4, and the x-axis. To determine the limits of integration, we need to find the points of intersection between the curve and the line.

Setting x = 4 in the equation [tex]x^2[/tex] = 8y, we have:

[tex]4^2[/tex] = 8y

16 = 8y

y = 2

So, the points of intersection are (4, 2) and (0, 0).

Now, let's consider an infinitesimally thin vertical strip of width Δx at a distance x from the y-axis. The height of this strip is given by the equation [tex]x^2[/tex] = 8y, which can be rearranged as y = ([tex]1/8)x^2[/tex].

The circumference of the cylindrical shell generated by revolving this strip is given by 2πx, and the height of the shell is Δx. Therefore, the volume of this cylindrical shell is approximately equal to 2πx * ([tex]1/8)x^2[/tex] * Δx.

To find the total volume, we integrate the expression for the volume over the range of x from 0 to 4:

V = ∫[0 to 4] 2πx * ([tex]1/8)x^2[/tex] dx

Evaluating the integral, we get:

V = (1/12)π * [[tex]x^4[/tex] [0 to 4]

V = (1/12)π * (4^4 - 0)

V = (1/12)π * 256

The specific solution to the system of differential equations with the initial conditions x(0) = -14 and y(0) = -3 is: [tex]x(t) = -4e^{(2t)} + 18e^{(3t)}, y(t) = -e^{(2t) }+ 4e^{(3t)[/tex].

To solve the system of differential equations, we'll use the method of finding eigen values and eigenvectors.

The given system of differential equations is:

x' = -23x + 108y

y' = -6x + 28y

To solve this system, we can rewrite it in matrix form:

X' = AX,

where X = [x, y] and A is the coefficient matrix:

A = [[-23, 108],

[-6, 28]]

To find the eigen values (λ) and eigenvectors (v) of A, we solve the characteristic equation:

|A - λI| = 0,

where I is the identity matrix.

The characteristic equation becomes:

|[-23-λ, 108],

[-6, 28-λ]| = 0.

Expanding the determinant, we get:

(-23 - λ)(28 - λ) - (108)(-6) = 0,

λ^2 - 5λ + 6 = 0.

Factoring the quadratic equation, we have:

(λ - 2)(λ - 3) = 0.

So, the eigenvalues are λ₁ = 2 and λ₂ = 3.

Now, we find the eigenvector corresponding to each eigen value.

For λ₁ = 2, we solve the equation (A - 2I)v₁ = 0:

[[-25, 108],

[-6, 26]] * [v₁₁, v₁₂] = [0, 0].

This leads to the equation:

-25v₁₁ + 108v₁₂ = 0,

-6v₁₁ + 26v₁₂ = 0.

Solving this system of equations, we find v₁ = [4, 1].

For λ₂ = 3, we solve the equation (A - 3I)v₂ = 0:

[[-26, 108],

[-6, 25]] * [v₂₁, v₂₂] = [0, 0].

This leads to the equation:

-26v₂₁ + 108v₂₂ = 0,

-6v₂₁ + 25v₂₂ = 0.

Solving this system of equations, we find v₂ = [9, 2].

Now, we can express the general solution of the system as:

X(t) = c₁e^(λ₁t)v₁ + c₂e^(λ₂t)v₂,

where c₁ and c₂ are constants.

Plugging in the values:

X(t) = c₁e^(2t)[4, 1] + c₂e^(3t)[9, 2],

Now, we'll use the initial conditions x(0) = -14 and y(0) = -3 to find the particular solution.

At t = 0, we have:

x(0) = c₁[4, 1] + c₂[9, 2] = [-14, -3].

This gives us the system of equations:

4c₁ + 9c₂ = -14,

c₁ + 2c₂ = -3.

Solving this system of equations, we find c₁ = -1 and c₂ = 2.

Therefore, the particular solution is:

X(t) = [tex]-e^{(2t)}[4, 1] + 2e^{(3t)}[9, 2].[/tex]

Thus, x(t) = [tex]-4e^{(2t)} + 18e^{(3t)}[/tex]and y(t) = [tex]-e^{(2t)} + 4e^{(3t).[/tex]

Substituting the initial conditions x(0) = -14 and y(0) = -3 into the particular solution, we have:

x(t) = [tex]-4e^{(2t)} + 18e^{(3t)[/tex]

y(t) = [tex]-e^{(2t)} + 4e^{(3t)[/tex]

At t = 0:

x(0) = [tex]-4e^{(2(0))} + 18e^{(3(0))[/tex] = -4 + 18 = 14

y(0) = [tex]-e^{(2(0))} + 4e^{(3(0))[/tex] = -1 + 4 = 3

Therefore, the specific solution to the system of differential equations with the initial conditions x(0) = -14 and y(0) = -3 is: x(t) = [tex]-4e^{(2t)} + 18e^{(3t)[/tex], y(t) = [tex]-e^{(2t)} + 4e^{(3t)}.[/tex]

To find a basis for the subspace W of R³, we need to determine a set of linearly independent vectors that span W. We can do this by solving the system of linear equations that defines W and identifying the free variables.

The given system of equations is:

a + 6 + c = 0,

6 + 2c - d = 0,

a - c + d = 0.

Rewriting the system in augmented matrix form, we have:

| 1 0 1 | 0 |

| 0 2 -1 | 6 |

| 1 -1 1 | 0 |

By row reducing the augmented matrix, we can obtain the reduced row echelon form:

| 1 0 1 | 0 |

| 0 2 -1 | 6 |

| 0 0 0 | 0 |

The row of zeros indicates that there is a free variable. Let's denote it as t. We can express the other variables in terms of t:

a = -t,

b = 6 - 3t,

c = t,

d = 2(6 - 3t) = 12 - 6t.

Now we can express the vectors in W as linear combinations of a basis:

W = {(-t, 6 - 3t, t, 12 - 6t)}.

To find a basis, we can choose two linearly independent vectors from W. For example, we can choose:

v₁ = (-1, 6, 1, 12) and

v₂ = (0, 3, 0, 6).

Therefore, a possible basis for the subspace W is {(-1, 6, 1, 12), (0, 3, 0, 6)}.

The power series for the exponential function centered at 0 is eˣ = Σ(xⁿ/n!) for n = 0 to infinity.

The power series representation of the exponential function is given by eˣ = 1 + x + x²/2! + x³/3! + x⁴/4! + ..., where n! denotes the factorial of n. In this series, each term represents the contribution of a specific power of x to the overall function. The coefficient of each term is determined by dividing the corresponding power of x by the factorial of the power.

Here is the calculation for the power series expansion of the exponential function centered at 0:

e^x = 1 + x + x²/2! + x³/3! + x⁴/4! + ...

The power series expansion is obtained by summing up the terms where each term is given by (xⁿ/n!), where n is the power of x.

For example, let's calculate the expansion up to the fourth term:

eˣ = 1 + x + x²/2! + x³/3! + x⁴/4!

= 1 + x + (x²)/(2) + (x³)/(6) + (x⁴)/(24)

This expansion can be continued further by adding more terms, providing a more accurate approximation of the exponential function for a given value of x.

This power series expansion allows us to approximate the exponential function for any real value of x by considering a finite number of terms. The more terms we include, the more accurate the approximation becomes.

To find the sum of two angles a and B, we can simply add the values of the angles together. In this case, a = 48°49' and B = 16°19'.

To add the angles, we start by adding the degrees and the minutes separately.

Adding the degrees: 48° + 16° = 64°

Adding the minutes: 49' + 19' = 68'

Now we have 64° and 68' as the sum of the two angles. However, since there are 60 minutes in a degree, we need to convert the minutes to degrees.

Converting the minutes: 68' / 60 = 1.13°

Adding the converted minutes: 64° + 1.13° = 65.13°

b.  The population after 12 days is approximately 1489.75 fish.

c. According to the model, it will take approximately 10.965 days for the entire trout population to die.

(a) To write an equation that models the population P in terms of the time t, we need to integrate the given rate of change equation.

dP/dt = 125e^(-t/15)

Integrating both sides with respect to t:

∫dP = ∫(125e^(-t/15)) dt

P = -1875e^(-t/15) + C

Since the population is 1875 when t = 0, we can use this information to find the constant C. Plugging in t = 0 and P = 1875 into the model equation:

1875 = -1875e^(0/15) + C

1875 = -1875 + C

C = 3750

Now we have the model equation for the population P in terms of time t:

P = -1875e^(-t/15) + 3750

(b) To find the population after 12 days, we can plug t = 12 into the model:

P = -1875e^(-12/15) + 3750

P ≈ 1489.75

Therefore, the population after 12 days is approximately 1489.75 fish.

(c) According to this model, the entire trout population will die when P = 0. To find the time it takes for this to happen, we can set P = 0 and solve for t:

0 = -1875e^(-t/15) + 3750

e^(-t/15) = 2

Taking the natural logarithm of both sides:

-ln(2) = -t/15

t = -15 * ln(2)

t ≈ 10.965

Therefore, according to the model, it will take approximately 10.965 days for the entire trout population to die.

The estimated area of f(x) = x^2 + 2 and the x-axis, using 4 rectangles with the left Riemann sum, is 22.

To use the left Riemann sum, we need to divide the interval [0, 4] into 4 equal subintervals.

The width of each rectangle, denoted as Δx, is calculated by dividing the total width of the interval by the number of rectangles.

In this case, Δx = (4 - 0) / 4 = 1.

Now, calculate the left Riemann sum.

The left Riemann sum is obtained by evaluating the function at the left endpoint of each subinterval, multiplying it by the width of the rectangle, and summing up these products for all the rectangles. In this case, we evaluate f(x) = x^2 + 2 at x = 0, 1, 2, and 3 (the left endpoints of each subinterval). Then we multiply each value by Δx = 1 and sum them up.

Then, estimate the area.

Using the left Riemann sum, we calculate the following values:

[tex]f(0) = 0^2 + 2 = 2\\f(1) = 1^2 + 2 = 3 \\f(2) = 2^2 + 2 = 6\\f(3) = 3^2 + 2 = 11[/tex]

The left Riemann sum is the sum of these values multiplied by Δx:

The power series representation for this term is simply x².

Combining the power series representations of the two terms, we have:

Σ[n=0 to ∞] (x⁴/9)(-1)ⁿ + x².

This represents the power series representation for the function f(x) = x⁴/9 + x².

To determine the study of convergence, we need to analyze the interval of convergence. Since both terms in the series are polynomials, the series will converge for all real numbers x.

Therefore, the power series representation for f(x) converges for all real values of x, indicating that f(x) is an entire function.

The derivative of function f(x) is given by:

f'(x) = 11

The Fundamental Theorem of Calculus states that if f(x) is continuous on [a, b] and F(x) is an antiderivative of f(x) on [a, b], then:
∫a to b f(x) dx = F(b) - F(a)

Using this theorem, we can find the derivative of the function slav(t) = ∫(-1) to 32-1 11 dt, where f(t) = 11:
slav'(t) = f(t) = 11

So, the derivative of slav with respect to t is a constant function equal to 11. In terms of the variable x, this would be:
f(x) = slav(x) = ∫(-1) to 32-1 11 dt = 11(32 - (-1)) = 363

Therefore, we can state that the derivative of f(x) is:
f'(x) = slav'(x) = 11

1). The limit lim(u→2) is √3/2.

2).The LHL, RHL, and the function value, we see that the LHL and RHL are not equal to the function value at a = 1. Therefore, the function is discontinuous at x = 1.

To evaluate the limit lim(u→2), we substitute u = 2 into the function expression:

lim(u→2) = √√(4u+1)/(3u-2)

Plugging in u = 2:

lim(u→2) = √√(4(2)+1)/(3(2)-2)

= √√(9)/(4)

= √3/2

Therefore, the limit lim(u→2) is √3/2.

The function f(x) is defined as follows:

f(x) = { √√(4x+1)/(3x-2) if x ≠ 1

{ 1 if x = 1

To determine if the function is discontinuous at a = 1, we need to check if the left-hand limit (LHL) and the right-hand limit (RHL) exist and are equal to the function value at a = 1.

(a) Left-hand limit (LHL):

lim(x→1-) √√(4x+1)/(3x-2)

To find the LHL, we approach 1 from values less than 1, so we can use x = 0.9 as an example:

lim(x→1-) √√(4(0.9)+1)/(3(0.9)-2)

= √√(4.6)/(0.7)

= √√6/0.7

(b) Right-hand limit (RHL):

lim(x→1+) √√(4x+1)/(3x-2)

To find the RHL, we approach 1 from values greater than 1, so we can use x = 1.1 as an example:

lim(x→1+) √√(4(1.1)+1)/(3(1.1)-2)

= √√(4.4)/(2.3)

= √√2/2.3

(c) Function value at a = 1:

f(1) = 1

Comparing the LHL, RHL, and the function value, we see that the LHL and RHL are not equal to the function value at a = 1. Therefore, the function is discontinuous at x = 1.

Probability of getting two red balls: 0.3529

Probability of getting a red and a blue ball in order: 0.4706

Given that both of the chosen balls are red, the probability that Urn 1 is chosen: 0.3333

To understand why the probability that Urn 1 is chosen, given that both of the chosen balls are red, is 0.3333, we can use Bayes' theorem.

Let's denote the events as follows:

A: Urn 1 is chosen

B: Both chosen balls are red

We are given the following probabilities:

P(B) = 0.3529 (probability of getting two red balls)

P(B') = 1 - P(B) = 1 - 0.3529 = 0.6471 (probability of not getting two red balls)

P(B|A) = 1 (since if Urn 1 is chosen, it contains only red balls)

P(B|A') = 0.4706 (probability of getting a red and a blue ball in order, given that Urn 1 is not chosen)

Now, we can apply Bayes' theorem:

P(A|B) = (P(B|A) * P(A)) / P(B)

We want to find P(A|B), the probability that Urn 1 is chosen given that both chosen balls are red.

Substituting the known values into the formula, we have:

P(A|B) = (1 * P(A)) / P(B)

We can also calculate P(A'|B), the probability that Urn 2 is chosen given that both chosen balls are red, using the complement rule:

P(A'|B) = 1 - P(A|B)

Since we only have two urns, P(A'|B) represents the probability that Urn 2 is chosen given that both chosen balls are red.

The sum of these two probabilities should be equal to 1, so we can write:

P(A|B) + P(A'|B) = 1

Substituting the values we have:

(1 * P(A)) / P(B) + P(A'|B) = 1

Simplifying the equation, we get:

P(A) / P(B) + P(A'|B) = 1

P(A) / P(B) + (1 - P(A|B)) = 1

P(A) / P(B) + 1 - (P(B|A) * P(A)) / P(B) = 1

P(A) / P(B) - (P(B|A) * P(A)) / P(B) = 0

Now, let's substitute the given values:

P(A) / 0.3529 - (1 * P(A)) / 0.3529 = 0

P(A) - P(A) = 0.3529 * 0.3333

2w - 4u = 12

Now, as per Leibniz notation differentiate both sides of the equation with respect to x:

d(2w)/dx - d(4u)/dx = d(12)/dx

Since w and u are functions of x, we can rewrite the equation as:

2(dw/dx) - 4(du/dx) = 0

Next, we are given additional equations:

y = w + 4u

u = 2x + x

Substituting the second equation into the first equation:

y = w + 4(2x + x)

y = w + 6x

Now, differentiate both sides of this equation with respect to x:

dy/dx = d(w + 6x)/dx

Since w is a function of x, we can write this as:

dy/dx = (dw/dx) + 6

Thus, the derivative dy/dx at x = -2 is simply:

The sum of the series 2, 6, 8, 32, and 128 is 242.

To determine the sum of the given series, let's analyze the pattern:

2, 6, 8, 32, 128

If we observe carefully, each term in the series is obtained by multiplying the previous term by 3. In other words, each term is three times the previous term.

Starting with the first term, 2, we can find the subsequent terms by multiplying each term by 3:

2 * 3 = 6

6 * 3 = 18

18 * 3 = 54

54 * 3 = 162

However, the series we have only includes the terms 2, 6, 8, 32, and 128, so the last term, 162, is not included.

To find the sum of the series, we can use the formula for the sum of a geometric series:

S = a * (rⁿ - 1) / (r - 1)

where:

S = sum of the series

a = first term

r = common ratio

n = number of terms

In this case, the first term (a) is 2, the common ratio (r) is 3, and the number of terms (n) is 5.

Plugging in these values, we get:

S = 2 * (3⁵ - 1) / (3 - 1)

S = 2 * (243 - 1) / 2

S = 2 * 242 / 2

S = 242

Therefore, the sum of the series 2, 6, 8, 32, and 128 is 242.

The center of the sphere is (-5, 3/2, -31), and its radius is [tex]\sqrt{(5675/4).[/tex]

To write the equation of the sphere in standard form, we need to complete the square for the terms involving x, y, and z.

Given the equation [tex]x^2 + y^2 + z^2 + 10x - 3y + 62z + 46 = 0[/tex], we can rewrite it as follows:

[tex](x^2 + 10x) + (y^2 - 3y) + (z^2 + 62z) = -46[/tex]

To complete the square for x, we add [tex](10/2)^2 = 25[/tex] to both sides:

[tex](x^2 + 10x + 25) + (y^2 - 3y) + (z^2 + 62z) = -46 + 25\\(x + 5)^2 + (y^2 - 3y) + (z^2 + 62z) = -21[/tex]

To complete the square for y, we add [tex](-3/2)^2 = 9/4[/tex] to both sides:

[tex](x + 5)^2 + (y^2 - 3y + 9/4) + (z^2 + 62z) = -21 + 9/4\\(x + 5)^2 + (y - 3/2)^2 + (z^2 + 62z) = -84/4 + 9/4\\(x + 5)^2 + (y - 3/2)^2 + (z^2 + 62z) = -75/4[/tex]

To complete the square for z, we add [tex](62/2)^2 = 961[/tex] to both sides:

[tex](x + 5)^2 + (y - 3/2)^2 + (z^2 + 62z + 961) = -75/4 + 961\\(x + 5)^2 + (y - 3/2)^2 + (z + 31)^2 = 3664/4 + 961\\(x + 5)^2 + (y - 3/2)^2 + (z + 31)^2 = 5675/4[/tex]

Now we have the equation of the sphere in standard form:

[tex](x + 5)^2 + (y - 3/2)^2 + (z + 31)^2 = 5675/4.[/tex]

The center of the sphere is given by the values inside the parentheses: (-5, 3/2, -31).

To find the radius, we take the square root of the right-hand side: sqrt(5675/4).

Therefore, the center of the sphere is (-5, 3/2, -31), and its radius is the square root of 5675/4.

. The magnitude of a vector represents its length or magnitude in space, while  direction of the vector is given by angle it makes with a reference axis. The direction is approximately -60.9 degrees or 299.1 degrees

The magnitude of a vector u = <-4, 7> can be calculated using the magnitude formula: ||u|| = √(x^2 + y^2), where x and y are the components of the vector.

For u = <-4, 7>, the magnitude is ||u|| = √((-4)^2 + 7^2) = √(16 + 49) = √65.

To find the direction of the vector, we can use trigonometric functions. The direction is given by the angle θ that the vector makes with a reference axis, typically the positive x-axis. The direction can be determined using the arctangent function:

θ = arctan(y/x) = arctan(7/-4).

Evaluating this expression, we find θ ≈ -60.9 degrees or approximately 299.1 degrees (depending on the chosen coordinate system and reference axis).

Therefore, the magnitude of vector u is √65, and the direction is approximately -60.9 degrees or 299.1 degrees, depending on the chosen coordinate system.

Let us first find the domain of the function f(x) = (5-x)/(x^2-16). It is clear that x ≠ -4 and x ≠ 4. Therefore, the domain of f(x) is (−∞,−4)∪(−4,4)∪(4,∞).f(x) can be expressed as f(x) =  A/(x-4) + B/(x+4), where A and B are constants. Let us find the values of A and B. We obtainA/(x-4) + B/(x+4) = (5-x)/(x^2-16).

Multiplying through by (x - 4)(x + 4) yieldsA(x+4) + B(x-4) = 5 - x.

If we substitute x = -4, we get 9A = 1. So, A = 1/9. If we substitute x = 4, we get −9B = 1.

So, B = -1/9.

Hence,f(x) = (1/9)/(x-4) - (1/9)/(x+4).

Now, we havef′(x) = (-1/81) * (1/(x-4)^2) + (1/81) * (1/(x+4)^2).

Since f′(x) is defined and continuous on (−∞,-4)∪(-4,4)∪(4,∞), the critical numbers are given by f′(x) = 0 = (-1/81) * (1/(x-4)^2) + (1/81) * (1/(x+4)^2).Multiplying through by (x - 4)^2(x + 4)^2 gives us- (x + 4)^2 + (x - 4)^2 = 0.

Simplifying this expression gives usx^2 - 20x + 12 = 0.

Solving for x gives usx = 10 + sqrt(88) / 2 or x = 10 - sqrt(88) / 2.

The critical numbers are therefore10 + sqrt(88) / 2 and 10 - sqrt(88) / 2.

The function is defined on the domain (−∞,-4)∪(-4,4)∪(4,∞) and is continuous there.

The values of f′(x) change from negative to positive as x increases from 10 - sqrt(88) / 2 to 10 + sqrt(88) / 2. Therefore, f(x) has a local minimum at x = 10 - sqrt(88) / 2 and a local maximum at x = 10 + sqrt(88) / 2.b)  g(x) = -2 + x^2e^(-.3x).

Let us first find the first derivative of the functiong(x) = -2 + x^2e^(-.3x).We haveg′(x) = 2xe^(-.3x) - .3x^2e^(-.3x).

The critical numbers are given by settingg′(x) = 0 = 2xe^(-.3x) - .3x^2e^(-.3x), which gives usx = 0 or x = 20/3.Let us examine the values of g′(x) to the left of 0, between 0 and 20/3, and to the right of 20/3.

For x < 0, g′(x) < 0. For x ∈ (0,20/3), g′(x) > 0. For x > 20/3, g′(x) < 0.

Therefore, g(x) has a local maximum at x = 0 and a local minimum at x = 20/3.
