Answer:

k =  4

Step-by-step explanation:

If (x + 2) is a factor then f(- 2) = 0

f(x) = x³ - kx² + 2x + 7k , then

f(- 2) = (- 2)³ - k(- 2)² + 2(- 2) + 7k = 0      

     ⇒   - 8 - k(4) - 4 + 7k = 0

     ⇒  - 8 - 4k - 4 + 7k = 0

     ⇒ 3k - 12 = 0 ( add 12 to both sides )

     ⇒ 3k = 12 (divide both sides by 3 )

     ⇒ k = 4

Original: 40.249223595

Simplified: 40.2

Step-by-step explanation:

There are 40 such bit strings.

To count the number of bit strings of length seven that either begin with two 0s or end with three 1s, we need to use the principle of inclusion-exclusion.

Let A be the set of bit strings that begin with two 0s, and let B be the set of bit strings that end with three 1s.

Then, we want to find the size of the set A ∪ B, which consists of bit strings that satisfy either condition.

The size of A can be calculated as follows:

since the first two digits must be 0, the remaining five digits can be any combination of 0s and 1s,

so there are \(2^5 = 32\) possible strings that begin with two 0s.

Similarly, the size of B can be calculated as follows:

since the last three digits must be 1, the first four digits can be any combination of 0s and 1s,

so there are\(2^4 = 16\) possible strings that end with three 1s.

However, we have counted the strings that both begin with two 0s and end with three 1s twice.

To correct for this, we need to subtract the number of strings that belong to both A and B from the total count.

The strings that belong to both A and B must begin with two 0s and end with three 1s, so they have the form 00111xxx,

where the x's can be any combination of 0s and 1s.

There are \(2^3 = 8\) such strings.

Therefore, the total number of bit strings of length seven that either begin with two 0s or end with three 1s is:

|A ∪ B| = |A| + |B| - |A ∩ B| = 32 + 16 - 8 = 40.

The Process of finding all the prime factors of a number is called prime factorization.

Prime factorization is the process of expressing a composite number as a product of its prime factors. In other words, it is the process of finding all the prime numbers that divide a given number exactly without leaving a remainder.

For example, the prime factorization of the number 20 is 2 x 2 x 5. This means that 20 is the product of the prime numbers 2 and 5, which are its prime factors.

Prime factorization is a fundamental concept in number theory and is used in many areas of mathematics, such as in the study of fractions, decimals, and rational numbers. It is also used in cryptography, where large numbers are factorized to ensure the security of encrypted messages.

The formula for the surface area of the box, in terms of the length of one side of the square base (s), is A = s^2 + 4s^2 = 5s^2.

The derivative of the surface area function with respect to s, denoted as dA/ds, gives us the rate of change of the surface area with respect to the length of one side of the base.

1. The surface area of the box consists of the area of the square base and the four equal sides. The area of the square base is s^2, and each side has a length of s. Therefore, the total surface area is given by A = s^2 + 4s^2 = 5s^2.

2. To find the derivative of the surface area function, we differentiate 5s^2 with respect to s using the power rule of differentiation. The power rule states that if we have a function f(x) = cx^n, then the derivative is f'(x) = cnx^(n-1).

  Applying the power rule, we have dA/ds = d(5s^2)/ds = 10s.

3. The derivative, dA/ds = 10s, represents the rate of change of the surface area with respect to the length of one side of the square base. This means that for every unit increase in s, the surface area increases by 10s units.

  The derivative does not provide information about minimizing the amount of material used. To find the dimensions of the box that minimize the amount of material used, we need to set up an optimization problem and solve for the critical points. This involves setting the derivative equal to zero and finding the values of s that satisfy this equation. However, since the problem statement does not provide a specific volume constraint or objective function, we cannot proceed with the optimization process.

The error between the nth partial sum and the actual sum is at most 0.0001, we need to take n to be at least 13,525.

The given series is Σ τα 25 (1+2), which can be written as Σ (3/τ^α), where α = 25. We know that this series converges by the integral test, so we can use that to estimate the value of its sum.

(a) The nth partial sum of the series is given by:

su = Σ (3/τ^α) from k = 1 to n

We can compute this sum using a calculator. For example, for n = 10, we have:

s10 = Σ (3/τ^25) from k = 1 to 10

= (3/1^25) + (3/2^25) + (3/3^25) + ... + (3/10^25)

≈ 0.6417

(b) The error bound for the integral test tells us that the error between the nth partial sum and the actual sum is at most the absolute value of the difference between the integral of the function and the nth partial sum. That is:

|s - sn| ≤ ∫(n+1, ∞) 3/τ^α dτ

We want to find a value of n such that this error bound is at most 0.0001. We can use the fact that the integral of 3/τ^α from n+1 to infinity is given by:

∫(n+1, ∞) 3/τ^α dτ = 3/(α-1) n^(1-α)

So we need to find the smallest value of n such that:

3/(α-1) n^(1-α) ≤ 0.0001

Simplifying this inequality, we get:

n ≥ [(3/(α-1)) / 0.0001]^(1/(1-α))

Plugging in α = 25, we have:

n ≥ [(3/24) / 0.0001]^(1/-24)

≈ 13,525

Therefore, to ensure that the error between the nth partial sum and the actual sum is at most 0.0001, we need to take n to be at least 13,525.

The value of z that divides the standard normal distribution so that half the area is on one side and half is on the other is 0.00.

To understand this better, let's visualize the standard normal distribution. The graph of the standard normal distribution is a bell-shaped curve that is symmetrical around the mean of 0.

When we say that half the area is on one side and half is on the other, we mean that the area under the curve to the left of the z-score is equal to the area under the curve to the right of the z-score.

Since the standard normal distribution is symmetric, this occurs when the z-score is equal to 0.00. At this point, the area to the left of 0.00 is 0.50 (or 50%), and the area to the right of 0.00 is also 0.50 (or 50%).

To find the critical points at which profit is maximized given the total revenue TR = 4700 - 302 and total cost TC = 320/10,500, we need to compute the marginal revenue and marginal cost, equate MR = MC to find the optimal quantity Q∗, verify if Q∗ is a relative maximum point, and compute the maximum profit level (π) by evaluating π∗ = 9(π(Q∗)).

Marginal Revenue (MR) is the derivative of the total revenue function with respect to quantity (Q). In this case, MR = dTR/dQ. By taking the derivative of TR = 4700 - 302 with respect to Q, we can find the expression for MR.

Marginal Cost (MC) is the derivative of the total cost function with respect to quantity (Q). In this case, MC = dTC/dQ. By taking the derivative of TC = 320/10,500 with respect to Q, we can find the expression for MC.

To find the optimal quantity Q∗, we equate MR and MC by setting MR = MC and solve for Q. This is because profit is maximized when MR equals MC.

Once we have found Q∗, we need to verify if it is a relative maximum point. This can be done by checking the second derivative of the profit function and determining if it is negative at Q∗. If the second derivative is negative, it confirms that Q∗ is a relative maximum point.

Finally, to compute the maximum profit level (π∗), we evaluate π(Q∗) by substituting Q∗ into the profit function. In this case, we can multiply the value of π(Q∗) by 9 to obtain the maximum profit level (π∗).

The present value of the loan is found to be  approximately $70.28.

To find the present value of a loan, we can use the formula:

Present Value = Future Value / (1 + (interest rate * time))

Given that the future value is $1,321.17, the interest rate is 7.75%, and the time is 230 days, we can plug in these values into the formula:

Present Value = 1321.17 / (1 + (0.0775 * 230))

Calculating the expression in the parentheses first:

Present Value = 1321.17 / (1 + 17.8075)

Simplifying further:

Present Value = 1321.17 / 18.8075

For the three infinite straight wires, the y-component force on one meter of wire carrying I1 is 2.48 × \(10^{-6}\) N, and the x-component force on one meter of wire carrying I2 is 1.96 × \(10^{-6}\) N.

A) To find Fx(1), we need to use the formula:

Fx(1) = I1 × L × Bx(1)

where L is the length of the wire, and Bx(1) is the x-component of the magnetic field at the location of the wire carrying current I1.

To find Bx(1), we can use the Biot-Savart law, which states that the magnetic field at a point due to a current-carrying wire is proportional to the current and inversely proportional to the distance from the point to the wire.

Bx(1) is the sum of the x-components of the magnetic fields due to the other two wires, which are:

B1x(1) = μ0 × I1 × I2 / (2πd)

B2x(1) = μ0 × I1 × I3 / (2πd)

where d is the distance between the wires, and μ0 is the permeability of free space.

Substituting the given values, we get:

B1x(1) = (4π × \(10^{-7}\) T·m/A) × 2 A × 1.2 A / (2π × 0.36 m) = 4.4 × \(10^{-7}\) T

B2x(1) = (4π × \(10^{-7}\) T·m/A) × 2 A × 6.9 A / (2π × 0.312 m) = 8.8 × \(10^{-7}\) T

Therefore, the total Bx(1) is:

Bx(1) = B1x(1) - B2x(1) = -4.4 × \(10^{-7}\) T

Substituting this value and the given length of 1 meter, we get:

Fx(1) = (2 A) × (1 m) × (-4.4 × \(10^{-7}\) T) = -8.8 × \(10^{-7}\) N

So the x-component of the force exerted on a one-meter length of the wire carrying current I1 is -8.8 × \(10^{-7}\) N.

B) To find Fy(1), we can use the same formula as above, but with the y-component of the magnetic field at the location of the wire carrying current I1:

Fy(1) = I1 × L × By(1)

where By(1) is the y-component of the magnetic field at the location of the wire carrying current I1, which is the sum of the y-components of the magnetic fields due to the other two wires:

B1y(1) = 0

B2y(1) = μ0 × I1 × I3 / (2πd)

Substituting the given values, we get:

B2y(1) = (4π × \(10^{-7}\) T·m/A) × 2 A × 6.9 A / (2π × 0.312 m) = 1.24 × \(10^{-6}\) T

Therefore, the total By(1) is:

By(1) = B1y(1) + B2y(1) = 1.24 × \(10^{-6}\) T

Substituting this value and the given length of 1 meter, we get:

Fy(1) = (2 A) × (1 m) × (1.24 × \(10^{-6}\) T) = 2.48 × \(10^{-6}\) N

So the y-component of the force exerted on a one-meter length of the wire carrying current I1 is 2.48 × \(10^{-6}\) N.

The x-component of the force exerted on a one-meter length of the wire carrying current I2 is 1.96 × \(10^{-6}\) N.

Step-by-step explanation:

Multiply them together.

Tammy divided 3 4/5 liters of fertilizer evenly among smaller bottles. To find the number of bottles she filled, we need to divide 3 4/5 by 1/3. To do this, we can convert the mixed number to an improper fraction by multiplying the whole number by the denominator and adding the numerator.

3 4/5 is equivalent to 19/5. Then, we can multiply 19/5 by the reciprocal of 1/3, which is 3/1. This gives us 19/5 x 3/1 = 57/5. Therefore, Tammy filled 57/5 or 11 2/5 smaller bottles with fertilizer.  Tammy divided 3 4/5 liters of fertilizer evenly among smaller bottles, with 1/3 liter in each bottle. To find the number of smaller bottles, first convert the mixed number to an improper fraction: (3 * 5 + 4)/5 = 19/5.

Now, divide the total amount of fertilizer (19/5) by the amount in each smaller bottle (1/3): (19/5) / (1/3) = (19/5) * (3/1) = 57/5. Since 57/5 is an improper fraction, we can convert it back to a mixed number: 57 ÷ 5 = 11 with a remainder of 2. Therefore, Tammy filled 11 smaller bottles with 1/3 liter of fertilizer each.
