You are starting a family pizza parlor and need to buy a motorcycle for delivery orders. You have two models in mind. Model A costs $8,600 and is expected to run for 6 years; Model B is more expensive, with a price of $15,100, and has an expected life of 10 years. The annual maintenance costs are $840 for Model A and $690 for Model B. Assume that the opportunity cost of capital is 10 percent. Calculate equivalent annual costs (EAC) of each models. (Do not round the discount factor. Round intermediate calculations and final answers to 2 decimal places, e.g. 15.25.)

The current flowing in the region where R > 2a/3 of the cylindrical wire with radius a = 200μm and uniform current density J = 2×10^8 A/m^2 is 2.67 A.

To calculate the current in the specified region, we first need to determine the length of that region. Let's consider the length of the wire as L. The length of the region where R > 2a/3 can be calculated as L' = L - 2π(2a/3), which simplifies to L' = L - (4πa/3).

Next, we can calculate the total current flowing through the wire using the current density formula: I = J × A, where I is the current, J is the current density, and A is the cross-sectional area of the wire. The cross-sectional area A is given by A = πa^2.

Since the current density is uniform, the total current I flowing through the wire is equal to J multiplied by the cross-sectional area A. Therefore, I = J × A = J × (πa^2).

Now, we can determine the current in the region where R > 2a/3 by multiplying the total current I by the ratio of the length of that region L' to the total length L. Therefore, the current in the specified region is given by I' = I × (L'/L).

Substituting the known values into the equations, we have:

I' = (2×10^8 A/m^2) × (π(200μm)^2) × [(L - (4π(200μm)/3)) / L]

I' = 2.67 A

Therefore, the current flowing in the region where R > 2a/3 is 2.67 A.

The function find(A) finds indices and * 2 points values of nonzero elements of an array A, it is true.

The first statement, "Relational operators can be applied to * 2 points only one size vectors," is not clear. It seems to be an incomplete sentence. Relational operators can be applied to vectors of any size, not just vectors with a single size.

Regarding the second statement, let's analyze it:

If `a = [1:5]`, it means that `a` is a vector with elements `[1, 2, 3, 4, 5]`.

If `b = 5 - a`, it means that each element of `b` is obtained by subtracting the corresponding element of `a` from 5. Therefore, `b` would be `[4, 3, 2, 1, 0]`.

Now, let's evaluate the given options:

- "a = 0 23 45" is false because the elements of `a` are `[1, 2, 3, 4, 5]`, not `0, 23, 45`.

- "b = 43210" is true because the elements of `b` are indeed `[4, 3, 2, 1, 0]`.

Therefore, the correct statement is: "a = 0 23 45" is false, and "b = 43210" is true.

The `find(A)` function in some programming languages, such as MATLAB or Octave, returns the indices of nonzero elements in the array `A`. It allows you to identify the positions of non-zero elements and access their values.

Part 1:The letters available are D, C, O, N, O, U. Since no letter is repeated, we can use the rule of permutations to find the number of 4-letter code words that can be formed. The formula for the number of permutations of n distinct objects taken r at a time is: P(n, r) = n!/(n-r)!We have 6 distinct objects (letters) and we want to take 4 of them.

Therefore, the number of 4-letter code words that can be formed without any repetition is:P(6, 4) = 6!/(6-4)! = 6!/2! = 6*5*4*3 = 360So, there are 360 possible 4-letter code words that can be formed if no letter is repeated.Part 2:If letters can be repeated, then we can use the rule of permutations with repetition. The formula for the number of permutations of n objects taken r at a time, with repetition, is:n^rWe have 6 objects and we want to take 4 of them, with repetition.

Therefore, the number of 4-letter code words that can be formed with repetition is:6^4 = 6*6*6*6 = 1,296So, there are 1,296 possible 4-letter code words that can be formed if letters can be repeated. and then we must choose a different letter for the third position, and then we must choose a different letter for the fourth position. After that, we can repeat the cycle starting with the first letter againAdjacent letters must be different: There are 120 possible 4-letter code words that can be formed.

Step-by-step explanation:

The point-slope form of the equation is y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope:

m = -6

(-3, 2)    ⇒   x₀ = -3,  y₀ = 2

The point-slope form of the equation:

y - 2 = -6(x + 3)

So:

y - 2 = -6x - 18         {add 2 to both sides}

y = -6x - 16             ←  the slope-intercept form of the equation

x = -5; y = 4, z = 1

Step-by-step explanation:

Given the row echelon form as:

\(\left[\begin{array}{cccc}1&0&\ \ 4|&-1\\0&1&-1|&3\\0&0&\ \ 1|&1\end{array}\right]\)

This matrix can be represented as:

\(\left[\begin{array}{ccc}1&0&4\\0&1&-1\\0&0&1\end{array}\right]\left[\begin{array}{c}x\\y\\z\end{array}\right] =\left[\begin{array}{c}-1\\3\\1\end{array}\right] \\\\Performing\ matrix\ multiplication\ gives:\\\\\left[\begin{array}{c}x+4z\\y-z\\z\end{array}\right] =\left[\begin{array}{c}-1\\3\\1\end{array}\right]\)

Therefore:

z = 1

y - z = 3;  

y = 3 + z = 3 + 1 = 4.

Hence, y = 4

x + 4z = - 1;

x = -1 - 4z = -1 - 4(1) = -5

x = -5

Information is needed to evaluate the project's financial viability, considering factors such as the initial investment, expected cash flows, cost of capital, and project duration.

To calculate the year 1 operating cash flows (OCF), we need to subtract the year 1 costs from the year 1 revenues:

OCF = Year 1 Revenues - Year 1 Costs

OCF = $192,000 - $125,000

OCF = $67,000

To find the depreciation expense in year 3, we need to determine the depreciation method. The provided information is incomplete regarding the depreciation method, so we cannot calculate the depreciation expense in year 3 without knowing the specific method.

The change in Net Working Capital (NWC) in year 2 can be determined by multiplying the Net Working Capital percentage (given as a percentage of t+1 revenues) by the year 1 revenues and subtracting the result from the year 2 revenues:

Change in NWC = (Year 2 Revenues - Net Working Capital percentage * Year 1 Revenues) - Year 1 Revenues

Without the specific Net Working Capital percentage or Year 2 Revenues values, we cannot calculate the exact change in NWC in year 2.

The net cash flow from salvage (ATSV) is calculated by multiplying the Salvage Value percentage by the Initial Cost:

ATSV = Salvage Value percentage * Initial Cost

ATSV = 28% * $390,000

ATSV = $109,200

To calculate the project's NPV, we need the cash flows for each year, the cost of capital, and the project duration. Unfortunately, the information provided does not include the cash flows for each year, so we cannot calculate the project's NPV.

The correct is (C) μ = -0.05 and σ = 0.15. The investigator is using the sample proportion p to estimate the true proportion of red blossoms in his hybrid plants.

The sample proportion p is expected to be normally distributed with a mean of μ = 0.15 and a standard deviation of σ = sqrt(p(1-p)/n), where n is the sample size. Substituting the values given, we get σ = sqrt(0.15(1-0.15)/50) = 0.05. However, since the investigator anticipates that the proportion of red blossoms is 0.15, he expects the sample proportion to be close to this value. Therefore, the mean of the sample proportion distribution should be close to the anticipated proportion, which is 0.15 - p = 0.15 - 0.15 = -0.05. Therefore, the correct answer is (C) μ = -0.05 and σ = 0.15. The investigator's anticipated proportion of red blossoms in his hybrid plants is 0.15. With a random sample of 50 plants, the sample proportion (p) follows a normal distribution. To determine the mean (μ) and standard deviation (σ), we can use the given information:
μ = p = 0.15 (anticipated proportion)
n = 50 (sample size)
We can calculate the standard deviation using the formula for binomial distribution:
σ = √(p(1-p)/n) = √(0.15(1-0.15)/50) = √(0.15*0.85/50) ≈ 0.05
Thus, the correct answer is (B) μ = 0.15 and σ ≈ 0.05.

Answer:

To find the amount of money after 10 years, we can use the formula for compound interest: A = P(1 + r/n)^(nt)

Where:

A = the amount of money after 10 years

P = the initial investment (24000 birr)

r = the interest rate (4%)

n = the number of times the interest is compounded per year

t = the number of years

In this case, since the interest is compounded annually, n = 1.

So,

A = 24000(1 + 0.04)^(1*10)

A = 24000(1.04)^10

A = 24000(1.46) = 24000*1.46 =35,040 birr

Let's start by setting up the equations to solve for this problem.

Let x be the amount of money John had initially.

Then, Mary had (384 - x) initially.

After John gave Php 36 to Mary, John had (x - 36) left and Mary had (384 - x + 36) = (420 - x).

We are told that Mary had three times as much money as John after this transaction, so we can write:

3(x - 36) = 420 - x

Simplifying this equation gives:

3x - 108 = 420 - x

The other endpoint is (-33, 17)

Step-by-step explanation:

The rule of the mid-point of a segment whose endpoints are

(\(x_{1}\), \(y_{1}\)) and (\(x_{2}\), \(y_{2}\)) is

In our question

∵ The coordinates of the endpoints of a segment are (-15, 13) and (x, y)

∴ \(x_{1}\) = -15 and \(x_{2}\) = x

∴ \(y_{1}\) = 13 and \(y_{2}\) = y

∵ The coordinates of the mid-point of this segment are (-24, 15)

∴ \(x_{M}\) = -24 and \(y_{M}\) = 15

→ Use the rule of the mid-point to find x and y

∵ \(-24=\frac{-15+x}{2}\)

→ Multiply both sides by 2

∴ -48 = -15 + x

→ Add 15 to both sides

∴ -33 = x

∵ \(15=\frac{13+y}{2}\)

→ Multiply both sides by 2

∴ 30 = 13 + y

→ Subtract 13 from both sides

∴ 17 = y

∴ The other endpoint is (-33, 17)
