The fourth roots are:

When we find the n-th roots of a complex number written in polar form, we divide the angle by n and find all the resulting angles by adding integer multiples of 2π/n.

The fourth roots of -4 are found by taking the angles

π/4, 3π/4, 5π/4, and 7π/4

(these are π/4 + k*(2π/4) f

or k = 0, 1, 2, 3).

The magnitude of the roots is the fourth root of the magnitude of -4, which is √2. So the roots are:

√2 * cis(π/4) = √2/2 + √2/2 * i

√2 * cis(3π/4) = -√2/2 + √2/2 * i

√2 * cis(5π/4) = -√2/2 - √2/2 * i

√2 * cis(7π/4) = √2/2 - √2/2 * i

These are the four fourth roots of -4.

The function f(x) = 2x^2 - 4x + 5 has a local minimum at x = 1.

To find when the function f(x) = 2x^2 - 4x + 5 has a local minimum, we can use Newton's quotient.

Step 1: Find the derivative of the function f(x) with respect to x.

The derivative of f(x) = 2x^2 - 4x + 5 is f'(x) = 4x - 4.

Step 2: Set the derivative equal to zero and solve for x to find the critical points.

Setting f'(x) = 0, we have 4x - 4 = 0. Solving for x, we get x = 1.

Step 3: Use the second derivative test to determine whether the critical point is a local minimum or maximum.

To do this, we need to find the second derivative of f(x). The second derivative of f(x) = 2x^2 - 4x + 5 is f''(x) = 4.

Step 4: Substitute the critical point x = 1 into the second derivative f''(x).

Substituting x = 1 into f''(x), we get f''(1) = 4.

Step 5: Interpret the results.

Since f''(1) = 4, which is positive, the function f(x) = 2x^2 - 4x + 5 has a local minimum at x = 1.

Therefore, the function f(x) = 2x^2 - 4x + 5 has a local minimum at x = 1.

The empirical rule provides three pieces of information about the sample that follows a skewed-right distribution:

1. Approximately 68% of the data falls within one standard deviation of the mean.

2. Approximately 95% of the data falls within two standard deviations of the mean.

3. Approximately 99.7% of the data falls within three standard deviations of the mean.

The empirical rule, also known as the 68-95-99.7 rule, is applicable to data that follows a normal distribution. Although it is mentioned that the sample follows a skewed-right distribution, we can still use the empirical rule as an approximation since the sample size is not specified.

1. The first piece of information states that approximately 68% of the data falls within one standard deviation of the mean. In this case, it means that about 68% of the data points in the sample would fall within the range of (66 - 17.9) to (66 + 17.9).

2. The second piece of information states that approximately 95% of the data falls within two standard deviations of the mean. Thus, about 95% of the data points in the sample would fall within the range of (66 - 2 * 17.9) to (66 + 2 * 17.9).

3. The third piece of information states that approximately 99.7% of the data falls within three standard deviations of the mean. Therefore, about 99.7% of the data points in the sample would fall within the range of (66 - 3 * 17.9) to (66 + 3 * 17.9).

Answer:

2,1

Step-by-step explanation:

The expression for the nth term of the sequence is 11 - 4n.

To find an expression for the nth term of the sequence, we need to identify the pattern and apply the given term-to-term rule.

Given that the third term is 11, we can assume that the first term is four less than the third term. Therefore, the first term can be calculated as:

First term = Third term - 4 = 11 - 4 = 7

Now, let's examine the pattern of the sequence based on the term-to-term rule of "take away 4". This means that each term is obtained by subtracting 4 from the previous term.

Using this pattern, we can express the nth term of the sequence as follows:

nth term = First term + (n - 1) * Difference

In this case, the first term is 7 and the difference between consecutive terms is -4. Therefore, the expression for the nth term is:

nth term = 7 + (n - 1) * (-4)

Simplifying this expression, we have:

nth term = 7 - 4n + 4

nth term = 11 - 4n

Thus, the expression for the nth term of the sequence is 11 - 4n.

This expression allows us to calculate any term in the sequence by substituting the value of n into the expression. For example, to find the 5th term, we would substitute n = 5:

5th term = 11 - 4(5) = 11 - 20 = -9

Similarly, we can find any term in the sequence using this expression.

We aim to maximize the objective function p = x - 7y while satisfying the given constraints: 2x + y ≤ 28 and y ≤ 5, with the additional non-negativity constraints x ≥ 0 and y ≥ 0.

By examining the constraints, we can graphically represent the feasible region. However, in this case, the feasible region is not explicitly defined. To determine the nature of the solution, we need to assess whether the feasible region is empty or if the objective function is unbounded.

Linear programming (LP) problems involve optimizing an objective function while satisfying a set of linear constraints. The feasible region represents the region in which the constraints are satisfied. In some cases, the feasible region may be empty, indicating no feasible solutions. Alternatively, if the objective function can be increased or decreased indefinitely, the LP problem is unbounded.

For question 8: a) gcd(ab, p^4) = p^3 b) gcd(a+b, p^4) = p^2

To show that one number in the subset S={1,2,3,...,100} must be a multiple of another number in the subset, we can apply the pigeonhole principle. Since there are 100 numbers in the set, but only 99 possible remainders when divided by 100 (ranging from 0 to 99), at least two numbers in the set must have the same remainder when divided by 100. Let's say these two numbers are a and b, with a > b. Then, a - b is a multiple of 100, and one number in the subset is a multiple of another number.

a) The gcd(ab, p^4) is p^3 because the greatest common divisor of a product is the product of the greatest common divisors of the individual numbers, and gcd(a, p^2) = p implies that a is divisible by p.

The maximum value of P = -x + 3y is 18, which occurs at the point (0, 6) within the feasible region.

Your friend made an error in setting up the constraints. The correct constraints should be:

y ≤ -2x + 6 (Equation 1)

y ≤ x + 3 (Equation 2)

x = 0 (Equation 3)

y = 0 (Equation 4)

The error lies in your friend mistakenly assuming that the values of x and y are equal to 0.

However, in this problem, we are looking for the maximum value of P, which means we need to consider the feasible region determined by the given constraints and find the maximum value within that region.

To find the correct solution, we first need to determine the feasible region by solving the system of inequalities.

We'll start with Equation 3 (x = 0) and Equation 4 (y = 0), which are the equations given in the problem. These equations represent the points (0, 0) in the xy-plane.

Next, we'll consider Equation 1 (y ≤ -2x + 6) and Equation 2 (y ≤ x + 3) to find the boundaries of the feasible region.

For Equation 1:

y ≤ -2x + 6

y ≤ -2(0) + 6

y ≤ 6

So, Equation 1 gives us the boundary line y = 6.

For Equation 2:

y ≤ x + 3

y ≤ 0 + 3

y ≤ 3

So, Equation 2 gives us the boundary line y = 3.

To determine the feasible region, we need to consider the overlapping area between the two boundary lines. In this case, the overlapping area is the region below the line y = 3 and below the line y = 6.

Therefore, the correct solution is to find the maximum value of P = -x + 3y within this feasible region. To do this, we can evaluate P at the corner points of the feasible region.

The corner points of the feasible region are:

(0, 0), (0, 3), and (0, 6)

Evaluating P at these points:

P(0, 0) = -(0) + 3(0) = 0

P(0, 3) = -(0) + 3(3) = 9

P(0, 6) = -(0) + 3(6) = 18

Therefore, the maximum value of P = -x + 3y is 18, which occurs at the point (0, 6) within the feasible region.

To determine the inequality that describes the number of boxes the worker can safely take on each trip, we need to consider the weight limits. The worker weighs 170 lb, and each box weighs 54 lb. Let's denote the number of boxes as b.

The total weight on the elevator should not exceed the weight limit of 2500 lb. Since the worker's weight and the weight of the boxes are added together, the inequality can be written as follows: 54b + 170 ≤ 2500.

However, since we want to determine the number of boxes the worker can safely take, we need to isolate the variable b. By rearranging the inequality, we get 54b ≤ 2500 - 170, which simplifies to 54b - 170 ≤ 2500.

It will take approximately 23 years for $600 to triple when invested at an annual interest rate of 5.3% compounded continuously.

Continuous compounding is a mathematical concept where interest is compounded infinitely often over time. The formula to calculate the future value (FV) with continuous compounding is given by FV = P * e^(rt), where P is the initial principal, e is the mathematical constant approximately equal to 2.71828, r is the annual interest rate as a decimal, and t is the time in years.

In this case, the initial principal (P) is $600, and we want to find the time (t) it takes for the investment to triple, which means the future value (FV) will be $1800. The annual interest rate (r) is 5.3% or 0.053 as a decimal.

Substituting the given values into the continuous compounding formula, we have 1800 = 600 * e^(0.053t). To solve for t, we divide both sides by 600 and take the natural logarithm (ln) of both sides to isolate the exponential term. This gives us ln(1800/600) = 0.053t.

Simplifying further, we get ln(3) = 0.053t. Solving for t, we divide both sides by 0.053, which gives t = ln(3)/0.053. Evaluating this expression, we find that t is approximately 23 years when rounded to the nearest year.

The project's discounted payback period is approximately 4.5 years.

The discounted payback period is a measure of the time it takes for a company to recover its initial investment in a new project, considering the time value of money.

The formula for the discounted payback period is as follows:

Discounted Payback Period = (A + B) / C

Where:

A is the last period with a negative cumulative cash flow

B is the absolute value of the cumulative discounted cash flow at the end of period A

C is the discounted cash flow in the period after A

The formula for discounted cash flow (DCF) is as follows:

DCF = FV / (1 + r)^n

Where:

FV is the future value of the investment

n is the number of years

r is the discount rate

Initial cost of the project, P = $14,000

Cash flow for Year 1, CF1 = $6,000

Cash flow for Year 2, CF2 = $6,000

Cash flow for Year 3, CF3 = $10,000

Discount rate, r = 18%

Discount factor for Year 1, DF1 = 1 / (1 + r)^1 = 0.8475

Discount factor for Year 2, DF2 = 1 / (1 + r)^2 = 0.7185

Discount factor for Year 3, DF3 = 1 / (1 + r)^3 = 0.6096

Discounted cash flow for Year 1, DCF1 = CF1 x DF1 = $6,000 x 0.8475 = $5,085

Discounted cash flow for Year 2, DCF2 = CF2 x DF2 = $6,000 x 0.7185 = $4,311

Discounted cash flow for Year 3, DCF3 = CF3 x DF3 = $10,000 x 0.6096 = $6,096

Cumulative discounted cash flow at the end of Year 3, CF3 = $5,085 + $4,311 + $6,096 = $15,492

Since the cumulative discounted cash flow at the end of Year 3 is positive, we need to find the discounted payback period between Year 2 and Year 3.

DCFA = -$9,396 (CF1 + CF2)

DF3 = 0.6096

DCF3 = CF3 x DF3 = $6,096 x 0.6096 = $3,713

To calculate the amount Brian will have after 6 years with simple interest, we can use the formula:

A = P(1 + rt)

Where:

A is the final amount

P is the principal amount (initial investment)

r is the interest rate per period

t is the number of periods

In this case, Brian invested £1800, the interest rate is 5% per year, and he invested for 6 years.

Substituting these values into the formula, we have:

A = £1800(1 + 0.05 * 6)

A = £1800(1 + 0.3)

A = £1800(1.3)

A = £2340

Therefore, Brian will have £2340 in his bank account after 6 years with 5% simple interest.

To determine the maximum height of the water in the bucket, we need to consider the shape of the bucket.

Assuming the bucket has a circular cross-section and the water fills the bucket completely, the maximum height can be calculated using the formula for the height of a cylinder.

The formula for the height of a cylinder is given by:

h = V / (π * r²)

where h is the height, V is the volume, and r is the radius of the circular base.

In this case, the outside diameter of the bucket is given as 31.2 cm. The radius can be calculated by dividing the diameter by 2:

r = 31.2 cm / 2 = 15.6 cm

The volume of the cylinder is equal to the volume of the bucket, which can be calculated using the formula for the volume of a cylinder:

V = π * r² * h

Since we want to find the maximum height, we need to find the maximum volume of the bucket. However, without additional information about the shape of the bucket or the volume of the bucket, it is not possible to determine the maximum height of the water in the bucket.

The solution of the higher-order differential equation y⁽⁴⁾ - y‴ + 2y = 0 is: y = C₁e^t + C₂cos(√2t) + C₃sin(√2t) + C₄t * e^t

where C₁, C₂, C₃, and C₄ are arbitrary constants.

Given the higher-order differential equation y⁽⁴⁾ - y‴ + 2y = 0.

To solve this equation, assume a solution of the form y = e^(rt). Substituting this form into the given equation, we get:

r⁴e^(rt) - r‴e^(rt) + 2e^(rt) = 0

⇒ r⁴ - r‴ + 2 = 0

This is the characteristic equation of the given differential equation, which can be solved as follows:

r³(r - 1) + 2(r - 1) = 0

(r - 1)(r³ + 2) = 0

Thus, the roots are r₁ = 1, r₂ = -√2i, and r₃ = √2i.

To find the solution, we can use the following steps:

For the root r₁ = 1, we get y₁ = e^(1t).

For the root r₂ = -√2i, we get y₂ = e^(-√2it) = cos(√2t) - i sin(√2t).

For the root r₃ = √2i, we get y₃ = e^(√2it) = cos(√2t) + i sin(√2t).

For the double root r = 1, we need to find a second solution, which is given by t * e^(1t).

The general solution of the differential equation is:

y = C₁e^t + C₂cos(√2t) + C₃sin(√2t) + C₄t * e^t

The above solution contains four arbitrary constants (C₁, C₂, C₃, and C₄), which can be evaluated using initial conditions or boundary conditions. Therefore, the solution of the higher-order differential equation y⁽⁴⁾ - y‴ + 2y = 0 is:

y = C₁e^t + C₂cos(√2t) + C₃sin(√2t) + C₄t * e^t

where C₁, C₂, C₃, and C₄ are arbitrary constants.

Since cosh(x) is a positive function, the value of cosh(x) in decimal form would be:

cosh(x) ≈ 34.007371 (rounded to six decimal places).

Sinh and cosh are hyperbolic functions frequently used in mathematics, particularly in topics such as calculus. The hyperbolic cosine of x (cosh(x)) can be calculated using the formula:

cosh(x) = (e^x + e^(-x))/2

To find the value of cosh(x) given that sinh(x) = 34, we can use the identity:

cosh^2(x) = sinh^2(x) + 1

Therefore, we can determine cosh(x) as:

cosh(x) = ±√(sinh^2(x) + 1)

Substituting sinh(x) = 34 into the formula, we get:

cosh(x) = ±√(34^2 + 1) ≈ ±34.007371

Since cosh(x) is a positive function, the value of cosh(x) in decimal form would be:

cosh(x) ≈ 34.007371 (rounded to six decimal places).

Hence, the answer is "34.007371."

The length of the radius of the cone is 9 units.

Surface area of a cone is the complete area covered by its two surfaces, i.e., circular base area and lateral (curved) surface area. The circular base area can be calculated using area of circle formula. The lateral surface area is the side-area of the cone

In this question, we have been given the surface area of a cone 216π square units.

We know that the surface area of a cone is:

[tex]\bold{A = \pi r(r + \sqrt{(h^2 + r^2)} )}[/tex]

Where

We need to find the radius of the cone.

The height of the cone is 5/3 times greater then the radius.

So, we get an equation, h = (5/3)r

Using the formula of the surface area of a cone,

[tex]\sf 216\pi = \pi r(r + \sqrt{((\frac{5}{3} \ r)^2 + r^2)})[/tex]

[tex]\sf 216 = r[r + (\sqrt{\frac{25}{9} + 1)} r][/tex]

[tex]\sf 216 = r^2[1 + \sqrt{(\frac{34}{9} )} ][/tex]

[tex]\sf 216 = r^2 \times (1 + 1.94)[/tex]

[tex]\sf 216 = r^2 \times 2.94[/tex]

[tex]\sf r^2 = \dfrac{216}{2.94}[/tex]

[tex]\sf r^2 = 73.47[/tex]

[tex]\sf r = \sqrt{73.47}[/tex]

[tex]\sf r = 8.57\thickapprox \bold{9 \ units}[/tex]

Therefore, the length of the radius of the cone is 9 units.

To find the diameter of the hollow rubber ball, we need to determine its radius first.

We know that the surface area of the ball is 50 square feet. Using the formula for the surface area of a sphere, which is A = 4πr^2, we can substitute the given surface area and solve for the radius:

50 = 4πr^2

Dividing both sides of the equation by 4π, we get:

r^2 = 50 / (4π)

r^2 ≈ 3.98

Taking the square root of both sides, we find:

r ≈ √3.98

Now that we have the radius, we can calculate the diameter by multiplying the radius by 2:

diameter ≈ 2 * √3.98

Therefore, the approximate diameter of the hollow rubber ball is approximately 3.16 feet.

The smallest number of iterations required in the bisection method to approximate the root of the function within 10⁻⁴ is 14, as determined by the error formula. The correct option is D.

To estimate the smallest number of iterations obtained from the error formula in the bisection method, we need to find the number of iterations required to approximate a root of the function f(x) = x³ − 6x² + 11x − 6 to within 10⁻⁴.

In the bisection method, we start with an interval [a₁, b₁] where f(a₁) and f(b₁) have opposite signs. Here, a₁ = 0.5 and b₁ = 1.5.

To determine the number of iterations, we can use the error formula:
error ≤ (b₁ - a₁) / (2ⁿ)
where n represents the number of iterations.

The error is required to be within 10⁻⁴, we can substitute the values into the formula:
10⁻⁴ ≤ (b₁ - a₁) / (2ⁿ)

To simplify, we can rewrite 10⁻⁴ as 0.0001:
0.0001 ≤ (b₁ - a₁) / (2ⁿ)

Next, we substitute the values of a1 and b1:
0.0001 ≤ (1.5 - 0.5) / (2ⁿ)
0.0001 ≤ 1 / (2ⁿ)

To isolate n, we can take the logarithm base 2 of both sides:
log2(0.0001) ≤ log2(1 / (2ⁿ))
-13.2877 ≤ -n

Since we want to find the smallest number of iterations, we need to find the smallest integer value of n that satisfies the inequality. We can round up to the nearest integer:
n ≥ 14

Therefore, the correct option is (D) n ≥ 14.
