The profitability index is 0.1237.

To find the profitability index (PI), we need to divide the present value of the cash flows by the initial investment.

To calculate the present value of the cash flows, we need to discount each cash flow to its present value and then add them up. Using a discount rate of 10%, we get:

Year 0: -$28,500 / [tex](1 + 0.10)^0[/tex]= -$28,500

Year 1: $15,200 /[tex](1 + 0.10)^1[/tex]= $13,818.18

Year 2: $13,700 / [tex](1 + 0.10)^2[/tex] = $10,881.68

Year 3: $10,100 /[tex](1 + 0.10)^3[/tex] = $7,322.51

The sum of the present values is:

PV = -$28,500 + $13,818.18 + $10,881.68 + $7,322.51 =

PV = $3,521.37

The profitability index is therefore:

PI = PV / Initial Investment = $3,521.37 / $28,500 = 0.1237

(a) The cost of City Bus for driving 10 miles = $3.

(b) The cost of City Bus for driving 25 miles = $7.5.

(c) The cost of City Bus for driving 42 miles = $12.6.

(d) The cost of City Bus for driving 68 miles = $20.4.

We previously choose City Bus as our mode transport since the per mile cost for City Bus is less.

Let the model for City Bus be f(x) = cx + d, where f(x) is total cost and x is number of miles.

From the table of Taxi we get, f(2) = 0.60; f(4) = 1.20; f(6) = 1.80 and f(8) = 2.40.

So, 2a + b = 0.60 and 4a + b = 1.20

(4a + b) - (2a + b) = 1.20 - 0.60

2a = 0.60

a = 0.60/2 = 0.30

Now, f(8) = 2.40

8*0.30 + b = 2.40

2.40 + b = 2.40

b = 2.40 - 2.40 = 0

So the function rule for City Bus is, f(x) = 0.3x.

(a) Total cost to drive 10 miles is,

f(10) = 0.3*10 = 3

(b) Total cost to drive 25 miles is,

Claude purchased 3 hardback books

What is the meaning of purchase?

Purchase refers to the act of buying or acquiring a product, service, or other item in exchange for money or some other form of payment. Purchases can be made by individuals, businesses, or other organizations, and can be made in a variety of ways, including online, in-store, or through a third-party vendor.

Let's assume that Claude purchased x paperback books and y hardback books.

From the problem statement, we can set up a system of two equations to represent the information given,

x + y = 10 (the total number of books Claude purchased is 10)

3x + 8y = 45 (the total cost of the books Claude purchased is $45)

We can use the first equation to solve for x in terms of y:

x = 10 - y

Substituting this into the second equation,

3(10 - y) + 8y = 45

Simplifying the equation,

30 - 3y + 8y = 45

5y = 15

y = 3

Therefore, Claude purchased 3 hardback books. To find the number of paperback books, we can use the equation we derived earlier:

The only possible value of k is k = 336675.

Suppose, for the sake of contradiction, that k is a prime such that k(k+2013) is a perfect square. Let's denote the perfect square as m^2, where m is a positive integer. Then we can write:

k(k+2013) = m^2

Expanding the left-hand side, we get:

k^2 + 2013k = m^2

Moving all the terms to one side, we get:

k^2 - m^2 + 2013k = 0

Using the difference of squares, we can factor this as:

(k - m)(k + m) + 2013k = 0

Since k is a prime, it must be greater than 1. Thus, k + m and k - m are both integers greater than 1 whose product is divisible by k. This means that at least one of them is divisible by k. Since k is prime, this can only happen if either k + m or km is equal to k. Thus, we have two cases to consider:

Case 1: k + m = k, which implies m = 0. But m is a positive integer, so this is impossible.

Case 2: k - m = k, which implies m = 0. But again, m is a positive integer, so this is impossible.

Therefore, our assumption that k is prime leads to a contradiction, and we conclude that k cannot be prime.

To find the correct value of k, note that k and k+2013 share a common factor of 3. Thus, we can write k = 3n and k+2013 = 3m for some integers n and m. Substituting these expressions into the equation k(k+2013) = m^2 and simplifying, we get:

3n(3n+2013) = m^2

n(3n+2013/3) = m^2/3

n(n+671) = m^2/3

Since n and n+671 are relatively prime, both n and n+671 must be perfect squares. Let's write n = p^2 and n+671 = q^2 for some integers p and q. Then we have:

q^2 - p^2 = 671

Using the difference of squares again, we can factor this as:

(q + p)(q - p) = 671

Since 671 is a prime, its only factors are 1 and 671. Therefore, we have two possibilities:

q + p = 671, q - p = 1, which implies q = 336, p = 335, n = p^2 = 112225, k = 3n = 336675

q + p = 671, q - p = 671, which implies q = 336 + 335 = 671, p = 0, which is not a valid solution since n cannot be negative.

k = 336675. is the best possible answer.

Isaiah needs to make at least 10 visits to the movie theater to earn his first free movie ticket.

To determine the number of visits Isaiah needs to earn his first free movie ticket, we can use an inequality. Let x be the number of visits he needs to make.

Isaiah earns 6.5 points for each visit, so the total points he earns after x visits is 6.5x.

He also received 75 points just for signing up, so the total number of points he has is 75 + 6.5x.

To earn a free movie ticket, he needs at least 140 points, so we can write the inequality:

Using approximation as x = 10, the estimation of y = 4.06 cm.

We need to find the area of the triangular cross-section of the prism. Since it is an isosceles right-angled triangle, we know that the two legs are equal in length, so let's call them x.

The area of a triangle is 1/2 * base * height, and in this case, the base and height are both x, so the area is 1/2 * x * x, or x^2/2.

Now, we can use the formula for the volume of a prism, which is V = area of base * height. In this case, the volume is 203 cm, and the height is y, so we can write:

203 = x^2/2 * y

To estimate the value of y, we need to make an assumption about the value of x. Since we don't have any information about it, let's assume it is about 10 cm (this is just an approximation).

Plugging in x = 10, we get:

203 = 10^2/2 * y
203 = 50 * y
y = 203/50
y ≈ 4.06 cm

So our estimate for y is 4.06 cm. Remember to include all the necessary terms and the final line, which should say: Estimate for y is 4.06 cm.

Step 3: Use the estimated proportion (p) from the previous poll, which is 21%, or 0.21. Calculate the estimated proportion for not favoring the single-payer system (q), which is 1 - p, or 0.79.

Step 4: Apply the formula for the minimum sample size (n):

n = (Z^2 * p * q) / E^2

n = (2.576^2 * 0.21 * 0.79) / 0.02^2

n ≈ 2506.73

Since you cannot have a fraction of a person, round up to the nearest whole number. The minimum sample size required is approximately 2507 individuals to accurately poll the proportion of Americans favoring a government-run, single-payer healthcare system within a 2% margin of error and with 99% confidence.

To solve this problem, we will need to use the equation of motion for a damped harmonic oscillator: mx'' + bx' + k*x = 0 . The position of mass after t seconds : [tex]x(t) = 4*e^(-3t/4)cos(tsqrt(55)/4)[/tex]

b is the damping constant, k is the spring constant, and x' and x'' are the first and second derivatives of x with respect to time, respectively.

We can start by finding the spring constant k using the given information Next, we can find the initial displacement, Oscillation and velocity of the mass: x(0) = 4 m x'(0) = 0 m/s

Now we can substitute these values and the values for m, b, and k into the equation of motion and solve for [tex]x: 8x'' + 18x' + 4*x = 0[/tex], The general solution to this equation is: [tex]x(t) = Ae^(-3t/4)cos(tsqrt(55)/4) + Be^(-3t/4)sin(tsqrt(55)/4)[/tex] where A and B are constants that depend on the initial conditions.

We can solve for these constants using the initial displacement and velocity: [tex]x(0) = A = 4 m x'(0) = -3sqrt(55)/4B = 0 B = 0[/tex]

Therefore, position of mass after t seconds: [tex]x(t) = 4*e^(-3t/4)cos(tsqrt(55)/4)[/tex]

As a result, the function's absolute maximum and minimum values are 5 and -45, respectively, at x = -5 and x = 2, respectively.

Every element in a set (referred to as the domain) in mathematics is connected by a rule known as a function to exactly one component in some other set (called the range or codomain). In other terms, a role is a connection among 2 sets where every element in the domain matches exactly one member in the range. Using a formula or equation with a variable input, function notation is a common way to represent functions. As an illustration, the formula f(x) = 2x + 1 gives each true figure x the value 2x + 1.

given

We can apply the second derivative test to determine whether this critical point is a maximum or minimum. By taking f'(xderivative, )'s we arrive at:

f''(x) = -4

The critical point at x = 0 is a local maximum since f"(0) = -4 is a negative value.

Secondly, we must determine whether the interval's endpoints of -5 x 2 provide values that are higher or lower than the crucial point. By entering x = -5 and x = 2, we obtain:

[tex]f(-5) = 5-2(-5) (-5)^2 = 5 – 50 = -45[/tex]

[tex]f(2) = 5 - 2(2) (2)^2 = -3[/tex]

As a result, the function's absolute maximum and minimum values are 5 and -45, respectively, at x = -5 and x = 2, respectively.

The value of h is 6 units.

The volume of the prism is given by the formula V = 1/3 x (base area) x height. Since the base of the prism is a right triangle, the area of the base is given by A = 1/2 x base x height of the triangle. Therefore, the volume of the prism can be written as V = 1/3 x 1/2 x base x height of the triangle x height of the prism.

Simplifying this expression, we get V = 1/6 x base x height^2. Given that the volume of the prism is 54 cubic units, and substituting the value of the base which is not given as per the formula we get, 54 = 1/6 x base x h^2. Solving for h, we get h = 6 units. Therefore, the value of h is 6 units.
