The eighth term of the given sequence is 2052.

To find the eighth term of the sequence, we need to understand how the terms are formed by multiplying corresponding terms of two arithmetic sequences. Let's denote the first arithmetic sequence as A and the second arithmetic sequence as B.

Looking at the given terms, we can observe that the terms of sequence A are 1440, 1716, 1848, and so on. To find the common difference (dA) of sequence A, we can subtract any two consecutive terms. Taking the difference between the second and first terms, we get dA = 1716 - 1440 = 276.

Similarly, the terms of sequence B are not explicitly given, but we can deduce them by dividing the given terms of the sequence by the corresponding terms of sequence A. Doing this, we find that the terms of sequence B are 1, 2, 3, and so on. Therefore, the common difference (dB) of sequence B is 1.

Now, to find the eighth term of the given sequence, we need to calculate the eighth term of sequence A and the eighth term of sequence B. The eighth term of sequence A can be found using the formula: An = a1 + (n - 1) * dA, where An represents the nth term of sequence A, a1 is the first term, n is the position of the term, and dA is the common difference. Plugging in the values, we have A8 = 1440 + (8 - 1) * 276 = 2052.

Since the terms of sequence B follow a simple arithmetic progression with a common difference of 1, the eighth term of sequence B is 8.

Finally, to obtain the eighth term of the given sequence, we multiply the corresponding terms of sequences A and B. Multiplying 2052 (eighth term of sequence A) and 8 (eighth term of sequence B), we get 2052 * 8 = 16416.

Therefore, the eighth term of the given sequence is 2052.

The first derivative of f(x): = (-2x² - 2) / (x² - 1)²

The second derivative of f(x): = 4 / (x² - 1)³

Here, we have,

To sketch the graph of the function f(x) = 2x/(x² - 1),

we will use the first and second derivatives to analyze its behavior.

Find the first derivative of f(x):

f'(x) = [(2)(x² - 1) - (2x)(2x)] / (x² - 1)²

= (2x² - 2 - 4x²) / (x² - 1)²

= (-2x² - 2) / (x² - 1)²

Find the second derivative of f(x):

f''(x) = [(2)(x² - 1)^2(2x² - 2) - (-2x² - 2)(2)(x² - 1)(2x)] / (x² - 1)⁴

= [4x⁴ - 4x² - 4x⁴ + 4 - 8x² + 8x²] / (x² - 1)⁴

= 4 / (x² - 1)³

Now let's analyze the behavior of the function using the derivatives:

Critical points occur where f'(x) = 0 or is undefined.

Setting f'(x) = 0:

(-2x² - 2) / (x² - 1)² = 0

This equation has no real solutions because the numerator is always negative while the denominator is always positive.

The function has vertical asymptotes at x = -1 and x = 1, where the denominator (x² - 1) becomes zero.

We can find the behavior of the function in different intervals by considering the signs of f'(x) and f''(x).

In the interval (-∞, -1), both f'(x) and f''(x) are positive. This indicates that the function is increasing and concave up in this interval.

In the interval (-1, 1), f'(x) is negative and f''(x) is positive. This indicates that the function is decreasing and concave up in this interval.

In the interval (1, ∞), both f'(x) and f''(x) are negative. This indicates that the function is decreasing and concave down in this interval.

Based on this analysis, we can sketch the graph of the function f(x) = 2x/(x² - 1):

The function has vertical asymptotes at x = -1 and x = 1.

The function is increasing and concave up in the interval (-∞, -1).

The function is decreasing and concave up in the interval (-1, 1).

The function is decreasing and concave down in the interval (1, ∞).

The sketch of the graph will show a curve approaching the vertical asymptotes and displaying the indicated behavior in each interval.

(d) [T(v)]B' = [7, -5] for [v]B' = [3, -2]. (e) Verified [v]B = [3, -2] and [T(v)] = [7, -5] match the calculations.

(a) To find the matrix A of T relative to the basis B, we need to find the images of the basis vectors (1,0) and (0,1) under the transformation T.

T(1,0) = (1 - 2(0), 1 + 4(0)) = (1,1)

T(0,1) = (0 - 2(1), 0 + 4(1)) = (-2,4)

Now, we can express the images of the basis vectors in terms of the basis B:

[1,1] = 1*[1,0] + 1*[0,1]

[-2,4] = -2*[1,0] + 4*[0,1]

Therefore, the matrix A of T relative to the basis B is:

A = [[1, -2], [1, 4]]

(b) To find the transition matrix P from B' to B, we need to express the basis vectors of B' in terms of the basis B.

(1,1) = 1*(1,0) + 1*(0,1)

(1,2) = 1*(1,0) + 2*(0,1)

Therefore, the transition matrix P from B' to B is:

P = [[1, 1], [1, 2]]⁻¹ (inverse of the matrix)

(c) To find the matrix A' of T relative to the basis B', we need to find the images of the basis vectors (1,1) and (1,2) under the transformation T.

T(1,1) = (1 - 2(1), 1 + 4(1)) = (-1,5)

T(1,2) = (1 - 2(2), 1 + 4(2)) = (-3,9)

Now, we can express the images of the basis vectors in terms of the basis B':

[-1,5] = 1*(1,1) + 4*(1,2)

[-3,9] = -3*(1,1) + 3*(1,2)

Therefore, the matrix A' of T relative to the basis B' is:

A' = [[1, -3], [4, 3]]

(d) To find [T(v)]B', we need to express v in terms of the basis B' and apply the transformation T.

[v]B' = [3, -2] (the coordinates of v in terms of basis B')

Applying the transformation T:

T(3, -2) = (3 - 2(-2), 3 + 4(-2)) = (7, -5)

Therefore, [T(v)]B' = [7, -5]

(e) To verify the answer in (d), we need to find [v]B and [T(v)].

To find [v]B, we need to express v in terms of the basis B:

[v]B = [3, -2]

To find [T(v)], we apply the transformation T to v:

T(3, -2) = (3 - 2(-2), 3 + 4(-2)) = (7, -5)

Therefore, [T(v)] = [7, -5]

This confirms that [T(v)]B' = [7, -5] as found in (d).

the area of the triangle with vertices (0, 0), (5, 3), and (1, 6) is 13.5 square units.

To find the area of a triangle with given vertices using calculus, we can use the Shoelace formula. The Shoelace formula calculates the area of a polygon given the coordinates of its vertices.

Let the vertices of the triangle be A(0, 0), B(5, 3), and C(1, 6).

The Shoelace formula states that the area of a triangle with vertices (x₁, y₁), (x₂, y₂), and (x₃, y₃) is given by:

A = 1/2 * |x₁(y₂ - y₃) + x₂(y₃ - y₁) + x₃(y₁ - y₂)|

Substituting the coordinates of the vertices into the formula, we get:

A = 1/2 * |0(3 - 6) + 5(6 - 0) + 1(0 - 3)|

Simplifying further:

A = 1/2 * |0 + 30 - 3|

A = 1/2 * 27

A = 13.5

Therefore, the area of the triangle with vertices (0, 0), (5, 3), and (1, 6) is 13.5 square units.

We have,

Based on the given sample data, we want to estimate the average of the entire population (population mean).

Assuming the population is normally distributed, we can calculate a confidence interval that provides a range of values within which the true population mean is likely to fall.

Using the sample data, we find that the sample mean (average of the data) is 46.275 and the sample standard deviation (measure of variability) is 13.994.

With a confidence level of 99.5%, we calculate the margin of error, which is a measure of the uncertainty in our estimate.

The margin of error is determined by the t-value, which takes into account the sample size and desired confidence level.

For our sample size of 8, the t-value is approximately 3.499.

Using the formula for the margin of error, we find that it is equal to 15.551.

Finally, we construct the confidence interval by subtracting and adding the margin of error to the sample mean.

The 99.5% confidence interval for the population mean is approximately from 30.724 to 61.826.

This means that we are 99.5%

The equation of the sphere passing through P(1,2,3) and Q(4,5,6) with its center at the midpoint of PQ is (x - 7/2)^2 + (y - 7/2)^2 + (z - 9/2)^2 = 27/2.

Given points are p(1,2,3) and q(4,5,6). We need to find the equation of the sphere passing through these points with its center at the midpoint of PQ. The midpoint of PQ is (x, y, z). We know that the center of the sphere lies at the midpoint of PQ.

So, we have:(1+x)/2 = 4-x/2 ...(i)

(since midpoint of PQ is (x,y,z), and P is (1,2,3) and Q is (4,5,6))

Substitute in eqn (i)

=> 1+x = 8 - x

=> x = 7/2

Similarly, we get:

y = 7/2

z = 9/2

Hence, the center of the sphere is C(7/2, 7/2, 9/2).

We know that the general equation of a sphere is given by

(x - h)^2 + (y - k)^2 + (z - l)^2 = r^2

where (h, k, l) is the center and r is the radius of the sphere. To find the radius, we use the distance formula. Let the radius be r.

Distance between P(1, 2, 3) and Q(4, 5, 6) is given by

√[(4 - 1)^2 + (5 - 2)^2 + (6 - 3)^2] = √27

Hence, the radius of the sphere is r = √27/2.

Let the equation of the sphere be (x - 7/2)^2 + (y - 7/2)^2 + (z - 9/2)^2 = 27/2. So, the equation of the sphere passing through P(1,2,3) and Q(4,5,6) with its center at the midpoint of PQ is

(x - 7/2)^2 + (y - 7/2)^2 + (z - 9/2)^2 = 27/2.

Conclusion: The equation of the sphere passing through P(1,2,3) and Q(4,5,6) with its center at the midpoint of PQ is (x - 7/2)^2 + (y - 7/2)^2 + (z - 9/2)^2 = 27/2.

Given that a sphere passes through P (1, 2, 3) and Q (4, 5, 6) with its center at the midpoint of PQ.

We need to find the equation of the sphere.

Step 1:

Find the center of the sphere.

We know that the center of the sphere lies at the midpoint of PQ.

The midpoint of PQ = $\frac{(P + Q)}{2}$

Midpoint of PQ = $\frac{(1 + 4, 2 + 5, 3 + 6)}{2}$

Midpoint of PQ = $(\frac{5}{2}, \frac{7}{2}, \frac{9}{2})$

Therefore, the center of the sphere is $(\frac{5}{2}, \frac{7}{2}, \frac{9}{2})$.

Step 2:

Find the radius of the sphere

Let the radius of the sphere be r.

Distance between P and Q is given by $\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2 + (z_2 - z_1)^2}$= $\sqrt{(4 - 1)^2 + (5 - 2)^2 + (6 - 3)^2}$= $\sqrt{9 + 9 + 9}$= $\sqrt{27}$= $3\sqrt{3}$

The radius of the sphere = $\frac{PQ}{2}$= $\frac{3\sqrt{3}}{2}$

Step 3:

Write the equation of the sphere

The equation of a sphere with center $(x_0, y_0, z_0)$ and radius r is given by $$(x - x_0)^2 + (y - y_0)^2 + (z - z_0)^2 = r^2$$

Therefore, the equation of the sphere passing through P(1, 2, 3) and Q(4, 5, 6) with its center at the midpoint of PQ is $$(x - \frac{5}{2})^2 + (y - \frac{7}{2})^2 + (z - \frac{9}{2})^2 = (\frac{3\sqrt{3}}{2})^2$$$$(x - \frac{5}{2})^2 + (y - \frac{7}{2})^2 + (z - \frac{9}{2})^2 = \frac{27}{2}$$

Hence, the equation of the sphere is $$(x - \frac{5}{2})^2 + (y - \frac{7}{2})^2 + (z - \frac{9}{2})^2 = \frac{27}{2}$$.

Force 2 has a magnitude of approximately 160.8 Newton.

To find the value of force2, we can use the concept of vector equivalence. If force1 has a magnitude of 258 Newton and a length of vector equal to 45 mm, and force2 has a length of vector equal to 28 mm, we can set up the following proportion:

|force1| / length of vector for force1 = |force2| / length of vector for force2

Substituting the given values:

258 / 45 = |force2| / 28

To solve for |force2|, we can cross-multiply and solve for it:

258 * 28 = 45 * |force2|

|force2| = (258 * 28) / 45

Calculating this expression gives us:

a)  The Taylor polynomial of degree 2 for f(x) = sec(x) centered at a = 0 is:

T2(x) = 1 + 0(x-0) + (1/2)(2)(x-0)^2

T2(x) = 1 + x^2

b)   The interval is [-0.1,0.1], we can take the maximum value of |x| to be 0.1. Thus,

|R2(x)| ≤ 0.25229 (rounded to six decimal places).

(a) The Taylor polynomial of degree 2 for f(x) = sec(x) centered at a = 0 is given by:

T2(x) = f(a) + f'(a)(x-a) + (1/2)f''(a)(x-a)^2

Since a=0 and f(x) = sec(x), we have:

f(0) = sec(0) = 1

f'(x) = sec(x)tan(x)

f'(0) = sec(0)tan(0) = 0

f''(x) = sec(x)tan^2(x) + sec(x)

f''(0) = sec(0)tan^2(0) + sec(0) = 2

Therefore, the Taylor polynomial of degree 2 for f(x) = sec(x) centered at a = 0 is:

T2(x) = 1 + 0(x-0) + (1/2)(2)(x-0)^2

T2(x) = 1 + x^2

(b) Taylor's Inequality states that if |f^(n+1)(c)| ≤ M for all x in the interval [a,x] and some constant M, then the remainder term Rn(x) satisfies the inequality:

|Rn(x)| ≤ M/[(n+1)!]|x-a|^(n+1)

In this case, we need to estimate the maximum value of the third derivative of f(x) = sec(x) on the interval [-0.1,0.1]. We have:

f'''(x) = sec(x)[3tan^2(x)+sec^2(x)]

Since sec(x) is always positive and increasing on the interval, we only need to consider the maximum value of 3tan^2(x)+sec^2(x) on the interval. This occurs at x = 0.1, and we have:

3tan^2(0.1)+sec^2(0.1) ≈ 9.025

So, we can take M = 9.025.

Using n = 2 and a = 0 in Taylor's Inequality, we get:

|R2(x)| ≤ 9.025/[(2+1)!]|x-0|^(2+1)

|R2(x)| ≤ 9.025/6|x|^3

Since the interval is [-0.1,0.1], we can take the maximum value of |x| to be 0.1. Thus,

and γ = (-(6i + 9) - √(-328i + 725)) / 14.

(a) The value of α + β + γ can be found by examining the coefficients of the quadratic term and the constant term in the equation.

In the given equation: 7x³ - 8x² + 23x + 30 = 0

The coefficient of the quadratic term is -8, and the constant term is 30.

According to Vieta's formulas, for a cubic equation of the form

ax³ + bx² + cx + d = 0, the sum of the roots is given by -b/a.

Therefore, in this case, α + β + γ = -(-8)/7 = 8/7.

(b) Given that 1 + 2i is a root of the equation, we can use the fact that complex roots always come in conjugate pairs.

Let's assume that α = 1 + 2i is one of the roots.

To find the other two roots, we can use polynomial division or synthetic division to divide the given equation by (x - α).

Performing the division, we have:

      7x² + (6i + 9)x + (14i - 23)

   ____________________________________

1 + 2i | 7x³ - 8x² + 23x + 30

Using long division or synthetic division, we find that the quotient is 7x² + (6i + 9)x + (14i - 23).

So, the remaining quadratic equation is 7x² + (6i + 9)x + (14i - 23) = 0.

Now we can find the roots of this quadratic equation using the quadratic formula:

x = (-b ± √(b² - 4ac)) / (2a)

In this case, a = 7, b = 6i + 9, and c = 14i - 23.

Substituting the values into the quadratic formula:

x = (-(6i + 9) ± √((6i + 9)² - 4(7)(14i - 23))) / (2(7))

x = (-(6i + 9) ± √(-328i + 725)) / 14

Since the discriminant is negative, we have complex roots.

Therefore, the other two roots are:

β = (-(6i + 9) + √(-328i + 725)) / 14

γ = (-(6i + 9) - √(-328i + 725)) / 14

Vertical asymptotes: [tex]\(x = 0\), \(x = 1\), \(x = -1\)[/tex]

Horizontal asymptote: [tex]\(y = 2\).[/tex]

To find the horizontal and vertical asymptotes of the given curve, we need to analyze the behavior of the function as it approaches infinity or certain points.

Let's start by determining the vertical asymptotes. Vertical asymptotes occur when the denominator of a rational function becomes zero.

In this case, the denominator is [tex]\(x - x^3\)[/tex]. To find the values of (x) that make the denominator zero, we set it equal to zero and solve for (x):

[tex]\(x - x^3 = 0\)[/tex]

Factoring out an (x), we get:

[tex]\(x(1 - x^2) = 0\)[/tex]

This equation is satisfied when (x = 0) or (x^2 = 1). Solving for (x) in the second equation, we find (x = 1) or (x = -1).

So, the vertical asymptotes occur at (x = 0), (x = 1), and (x = -1).

Next, let's determine the horizontal asymptote. To find the horizontal asymptote, we need to examine the behavior of the function as \(x\) approaches positive or negative infinity.

To determine the horizontal asymptote, we can compare the degrees of the numerator and denominator polynomials. The given function is:

[tex]\(y = \frac{1 + 2x^3}{x - x^3}\)[/tex]

The degree of the numerator is 3, and the degree of the denominator is also 3. Since the degrees are the same, we compare the leading coefficients of the polynomials.

The leading coefficient of the numerator is 2, and the leading coefficient of the denominator is 1.

Therefore, the horizontal asymptote occurs when (x) approaches infinity or negative infinity and is given by the ratio of the leading coefficients. In this case, the horizontal asymptote is

[tex]\(y = \frac{2}{1} = 2\)[/tex]

To summarize:

Vertical asymptotes: (x = 0), (x = 1), (x = -1)

Horizontal asymptote: (y = 2).

(1 + 0.05) x (1 + 0.17) x (1 + 0.64) x (1 - 0.35) = 1.05 x 1.17 x 1.64 x 0.65 ≈ 1.757

Step 3: Calculate the geometric mean:

Geometric mean = (product of (1 + r))^(1/n)

where n is the number of years

Geometric mean = 1.757^(1/4) ≈ 1.0948

Therefore, the average annual rate of return (geometric mean) for the given stock over the four-year period is approximately 9.48%.

The reliability coefficient determined by the correlation between scores on half of the items on a measure with scores on the other half of the measure is called split-half reliability.

This method is commonly used to estimate the internal consistency of a measurement instrument. The measure is divided into two halves, and the scores on one half are compared to the scores on the other half using correlation analysis.

A high correlation indicates that the two halves of the measure are consistent and reliable in measuring the same construct. However, split-half reliability assumes that the two halves of the measure are equivalent and that the items are interchangeable, which may not always be the case. Other methods, such as Cronbach's alpha, may be used to assess reliability more accurately.

Based on the scenario you provided, it seems like the following events occurred:

The owner obtained a loan of $60,000 from a bank and secured it with a mortgage on his land.

The owner obtained another loan of $60,000 from a lender and secured it with a mortgage on the same land.

The owner sold the land to a buyer for $150,000 and the buyer agreed to assume both mortgages with the consent of the bank and the lender.

The bank loaned the buyer an additional $50,000, which was added to the principal amount and interest rate of its original mortgage.

The buyer stopped making payments on both mortgages and disappeared.

The bank initiated a foreclosure action on its mortgage and purchased the property at the foreclosure sale.

The proceeds from the foreclosure sale totaled $80,000 after fees and expenses.

Since the bank's mortgage was recorded first, it has priority over the lender's mortgage. Therefore, when the property was sold at the foreclosure sale, the proceeds were used to pay off the bank's outstanding balance of $50,000 first. The remaining $30,000 was then applied to the lender's mortgage, leaving a balance of $20,000.

However, since the buyer disappeared and did not pay the remaining balance on the lender's mortgage, the lender may still be able to pursue legal action to recover the remaining debt from the buyer. It is also possible that the lender could try to recover the debt from the owner who sold the property, depending on the terms of the mortgage agreement.

There are 266 number of  ways to park 3 distinct cars in 9 consecutive parking slots such that at least one parking slot remains vacant between any two cars.

To determine the number of ways to park 3 distinct cars in 9 consecutive parking slots such that at least one parking slot remains vacant between any two cars, we need to consider the possible arrangements.

Let's analyze the scenario:

1. All three cars are parked in adjacent slots

In this case, there are 7 possible positions where the first car can be parked (as it needs at least one vacant slot on the right side), 6 possible positions for the second car (as it also needs one vacant slot on the right side), and the third car will occupy the remaining slot.

Total arrangements for Case 1 = 7 * 6 = 42.

2. One vacant slot between the cars

In this case, there are 7 possible positions where the first car can be parked (as it needs at least one vacant slot on the right side).

After parking the first car, there will be 5 remaining slots where the second car can be parked (one vacant slot between the first and second car).

The third car will occupy one of the remaining 4 slots.

Total arrangements for Case 2 = 7 * 5 * 4 = 140.

3. Two vacant slots between the cars

In this case, there are 7 possible positions where the first car can be parked (as it needs at least one vacant slot on the right side).

After parking the first car, there will be 4 remaining slots where the second car can be parked (two vacant slots between the first and second car).

The third car will occupy one of the remaining 3 slots.

Total arrangements for Case 3 = 7 * 4 * 3 = 84.

The volume of the parallelepiped with given adjacent edges pq, pr, and ps is equal to 102 cubic units.

To find the volume of the parallelepiped with adjacent edges pq, pr, and ps,

Use the scalar triple product.

The volume of the parallelepiped formed by three vectors can be calculated as the absolute value of their scalar triple product.

Let's denote the vectors formed by the adjacent edges as,

pq = q - p

    = (-4 - 1, 1 - 0, 8 - 2)

    = (-5, 1, 6)

pr = r - p

    = (4 - 1, 3 - 0, 0 - 2)

    = (3, 3, -2)

ps = s - p

    = (-1 - 1, 4 - 0, 5 - 2)

    = (-2, 4, 3)

Now, let's calculate the scalar triple product,

V = |pq · (pr × ps)|

where pr × ps denotes the cross product of vectors pr and ps.

pr × ps = (3, 3, -2) × (-2, 4, 3)

= (18 - 12, -6 - 6, 12 + 12)

= (6, -12, 24)

Now, let's calculate the dot product of pq and the cross product of pr and ps,

pq · (pr × ps) = (-5, 1, 6) · (6, -12, 24)

= -56 + 1(-12) + 6(24)

= -30 - 12 + 144

= 102

Finally, let's calculate the absolute value of the scalar triple product,

V = |pq · (pr × ps)|

= |102|

= 102

Therefore, the volume of the parallelepiped with adjacent edges pq, pr, and ps is 102 cubic units.

The utility function u(x) = 0.25**(x/200) is consistent with Pablo's preferences.

To determine which utility function, represented by u(x), is consistent with Pablo's preferences, we need to compare the utility values for different prospects.

Pablo's certain equivalent for a deal with a 0.8 chance at $500 and a 0.2 chance at $100 is $300. We can calculate the expected value of this prospect:

Expected value = (0.8 * $500) + (0.2 * $100) = $400 + $20 = $420

Now let's evaluate the utility values for the given utility functions and compare them to $300 and $420.

a) u(x) = 10 - 10x^4 - x/200

If we substitute x = $420 into this utility function, we get:

u($420) = 10 - 10($420)^4 - $420/200 ≈ -1.06 x 10^18

b) u(x) = 1 - 0.25 - x/200

If we substitute x = $420 into this utility function, we get:

u($420) = 1 - 0.25 - $420/200 = 1 - 0.25 - 2.1 ≈ -1.35

c) u(x) = 5 - 2x^4 + x/300

If we substitute x = $420 into this utility function, e get:

u($420) = 5 - 2($420)^4 + $420/300 ≈ -1.59 x 10^16

d) u(x) = 0.25**(x/200)

If we substitute x = $420 into this utility function, we get:

u($420) = 0.25**(420/200) ≈ 0.063

Comparing the utility values to Pablo's certain equivalent ($300) and the expected value ($420), we find that option d) u(x) = 0.25**(x/200) is consistent with Pablo's preferences, as it yields a utility value (0.063) closer to the expected value than the others.

We need to find the partial derivatives of F with respect to x, y, and z. Given, F(x, y, z) = ⟨y²+yz+2x, 2xy+ez+xz, yez+xy⟩

To check if F(x, y, z) = yez+xy = f

= ∇f, we need to find the partial derivatives of F with respect to x, y, and z.

f = ∂∂(y²+yz+2x)

= 2f = ∂∂(y²+yz+2x)

= 2y+zf

= ∂∂(y²+yz+2x)

= y

Now, ∇f = ⟨2, 2y+z, y⟩

Now, let's compare both F and ∇f.∇ = ⟨2, 2+, ⟩F(x, y, z)

= ⟨y²+yz+2x, 2xy+ez+xz, yez+xy⟩

Therefore, F(x, y, z)

= ∇f only if:∂f/∂x

= y²+yz+2x

= f∂f/∂y

= 2xy+ez+xz

= f∂f/∂z

= yez+xy

= f

For part (C), we are given Q, which consists of line segments from (1,0,1) to (3,15) to (−2,0,1) and finally to (0,20). We need to calculate W for F(x,y,z).W = ∫CF·drwhere C is the given path in Q, and F is the given vector field.Substituting the points from (1,0,1) to (3,15), we get:W = ∫CF·dr = ∫C(F·T)ds

where T is the unit tangent vector of C, and s is the arc length parameter.

Using the above formula, we get

:W = ∫C(F·T)ds= ∫C(y²+yz+2x)dx + (2xy+ez+xz)dy + (yez+xy)dz

Now, we have C = C1 + C2 + C3, where:C1 is the line segment from (1,0,1) to (3,15)C2 is the line segment from (3,15) to (-2,0,1)C3 is the line segment from (-2,0,1) to (0,20)We can use the parametric equations of C1, C2, and C3 to evaluate the integrals as follows:C1: r(t)

= ⟨1+2t,0+t,1+t⟩, 0 ≤ t ≤ 1C2: r(t)

= ⟨3-5t,15-15t,1+t⟩, 0 ≤ t ≤ 1C3: r(t)

= ⟨-2+2t,0+2t,1⟩, 0 ≤ t ≤ 1Substituting the values of C1 in the above formula, we get:∫C1(F·T)ds

= ∫₀¹(y²+yz+2x)dx + (2xy+ez+xz)dy + (yez+xy)dz

= ∫₀¹(2t+1)²+(2t+1)(1+t)+(2+2t)2t dt+ ∫₀¹2(2t+1)t(15-15t) dt+ ∫₀¹(2t+1)et(2t) dt

Again, substituting the values of C2 in the above formula,

we get:∫C2(F·T)ds = ∫₀¹(y²+yz+2x)dx + (2xy+ez+xz)dy + (yez+xy)

dz= ∫₀¹(-25t²+90t+212)dt+ ∫₀¹(-2t²+14t+90)dt+ ∫₀¹(15t+15t²)et dt

Finally, substituting the values of C3 in the above formula,

we get:∫C3(F·T)ds

= ∫₀¹(y²+yz+2x)dx + (2xy+ez+xz)dy + (yez+xy)dz

= ∫₀¹4dt+ ∫₀¹-4t²-4t+14 dt+ ∫₀¹(2t+1)e² dt

Now, adding all the values of the three integrals above, we get:

W = ∫C(F·dr)

=∫C1(F·dr) + ∫C2(F·dr) + ∫C3(F·dr)

= ∫C1(F·T)ds + ∫C2(F·T)ds + ∫C3(F·T)ds

= ∫₀¹(2t+1)²+(2t+1)(1+t)+(2+2t)2t dt+ ∫₀¹2(2t+1)t(15-15t) dt+ ∫₀¹(2t+1)et(2t) dt+ ∫₀¹(-25t²+90t+212)dt+ ∫₀¹(-2t²+14t+90)dt+ ∫₀¹(15t+15t²)et dt+ ∫₀¹4dt+ ∫₀¹-4t²-4t+14 dt+ ∫₀¹(2t+1)e² dt

The value of the given infinite series of ∑ from n=1 to ∞ of ​(n²+2)/2 is -3.

We have to evaluate the value of,

∑ from n=1 to ∞ of ​(n²+2)/2.

This means we need to add up all the terms in the sequence,

Starting with n=1 and going all the way up to infinity.

To do this, we can use a formula for the sum of an infinite series.

We can use the formula for an infinite geometric series, which is:

S = a / (1 - r)

Where S is the sum of the series,

a is the first term,

And r is the common ratio between consecutive terms.

In our case,

The first term is (1²+2)/2 = 1.5, and the common ratio is (n²+2)/2.

We can write this as:

r = (n²+2)/2

Now we need to plug these values into the formula. We get:

S = 1.5 / (1 - (n²+2)/2)

Simplifying this expression, we get:

S = 3 / (4 - n²)

Now we need to evaluate this expression as n approaches infinity.

We can do this by taking the limit as n approaches infinity.

We get:

limit n tends to infinity of S = limit n tends to infinity of (3 / (4 - n²))

Using L'Hopital's rule, we can simplify this expression to:

limit n tends to infinity of S =  limit n tends to infinity of (-6n / (2n))

Simplifying further, we get:

limit n tends to infinity of S =  limit n tends to infinity of (-3)

Therefore, the sum of the series is -3.

Hence, the value of the given infinite series is -3.

B)

The apparent weight of both the driver and the scooter at the top of the hill is;

F_net = 779.1 N

given;

Mass; m = 159 kg

Radius; r = 480 m

A) Since it's motion about a circular hill, it means we are dealing with centripetal force.

Formula for centripetal force is given as;

F = mv²/r

Now, we want to find the speed of the scooter if the driver feels weightlessness.

This means that the centripetal force would be equal to the gravitational force.

Thus;

mg = mv²/r

m will cancel out to give;

v²/r = g

v² = gr

v = √(gr)

v = √(9.8 × 480)

v = √4704

v = 68.586 m/s

B) Now, he is travelling with speed of;

v = 68.586 m/s

And the radius is 2r

Let's first find the centripetal acceleration from the formula; α = v²/r

Thus; α = 4704/(2 × 480)

α = 4.9 m/s²

Now, since he has encountered a hill with a radius of 2r up the slope, it means that the apparent weight will now be;

F_app = m(g - α)

F_net = 159(9.8 - 4.9)

F_net = 779.1 N

If curl of a vector field is zero, then the given vector field is conservative.The curl of the given vector field F is given by:

curl F= ∂Q/∂x i + ∂Q/∂y j + ∂Q/∂z k

Where, Q is the potential function of the given vector field F.

the formula for the slope of the tangent line to the function f(x) = 1/x is f'(x) = -1/(x²).

To find the slope of the tangent line to a function f(x) at a given point, we can use the concept of the derivative. The derivative of a function represents the rate at which the function is changing at any given point.

For the function f(x) = 1/x, we can find the derivative by taking the limit of the difference quotient as it approaches zero. The difference quotient is given by:

f'(x) = lim(h->0) [(f(x + h) - f(x))/h]

Let's calculate the derivative of f(x) using this formula:

f'(x) = lim(h->0) [(1/(x + h) - 1/x)/h]

To simplify the expression, we need to find a common denominator:

f'(x) = lim(h->0) [((x - (x + h))/(x(x + h)))/h]

Now, we can simplify further:

f'(x) = lim(h->0) [-h/(x(x + h)h)]

f'(x) = lim(h->0) [-1/(x(x + h))]

Finally, we can take the limit as h approaches zero:

f'(x) = -1/(x²)
