Tri-County will have to charge approximately $83.1 per MWh to break even.

To calculate the break-even price that Tri-County will have to charge to cover its costs, we need to consider both the fixed costs and the variable costs. The fixed costs are given as $80.1 million per year.

The variable costs are calculated by multiplying the quantity of electrical power sold (150,000 MWh per year to Boulder) by the variable cost per MWh ($20). Therefore, the variable costs amount to 150,000 MWh/year * $20/MWh = $3 million per year.

To cover both fixed and variable costs, Tri-County needs to charge a total amount that equals the sum of these costs. The total cost is $80.1 million + $3 million = $83.1 million per year.

Now, let's calculate the break-even price per MWh. Since Tri-County has a demand of 1,000,000 MWh from its customers (other than Boulder), we can divide the total cost by this quantity to find the break-even price.

Break-even price = Total cost / Quantity of electrical power demanded
Break-even price = $83.1 million / 1,000,000 MWh = $83.1/MWh

Therefore, Tri-County will have to charge approximately $83.1 per MWh to break even.

Vertical compressions occur when a function is multiplied by a rational scale factor. The base of the function’s graph remains the same when a graph is compressed vertically. Only the output values will be affected.

Vertical compressions occur when a function is multiplied by a rational scale factor. The base of the function’s graph remains the same when a graph is compressed vertically. Only the output values will be affected.

Here are some important reminders when vertically compressing a given function’s graph or expression:

Example :

The table of values for f(x) is shown below. If h(x) = 1/2 ∙ f(x), construct a table of values for the function h(x).

x -3 -2 -1 0 1 2 3

f(x) 20 10 4 2 4 10 20

solution:

Let’s start with one of the ordered pairs from f(x): (1, 2). Since we want to compress f(x) vertically by 1/2, we’ll multiply the y-coordinate by the same factor.

(1, 2) → (1, 1)

\(\pi \int\limits^6_0 {\frac{26}{3} } \, x^{2} -\frac{1}{9} x^{4} dx\) is the integral that uses the method of disks/washers to find the volume v of the solid obtained by rotating the region bounded by the given curves about the specified lines.

A method for determining the volume of a solid of revolution of a solid-state material while integrating along an axis "parallel" to the axis of revolution is known as disc integration, also known as the disc method in integral calculus.

This technique stacks an endless number of discs with varied radii and minuscule thickness to produce the final three-dimensional form. To create hollow solids of revolutions, the same ideas may also be applied when using rings in place of discs (this is known as the "washer technique").

As opposed to this, shell integration integrates along an axis that is parallel to the axis of revolution. The solution can be seen in the attached images below.

Step-by-step explanation:

Answer:

{12}

Step-by-step explanation:

isolate the radical expression

\(\sqrt{3x} = x-6\)

raise both sides to the index of the radical in this case 2

\((\sqrt{3x} )^{2} = (x-6)^2\)

\(3x = (x-6)^2\)

foil the right hand side or multiply (x-6)(x-6)

\(3x = x^{2} -6x-6x+36\)

subtract 3x from both sides and combine like terms

\(0=x^{2} -15x+36\)

factor

\(0=(x-12)(x-3)\)

set each factor equal to zero and solve for x

x - 12 = 0 and x - 3 = 0

     x = 12 and     x  = 3

We need to find the probability that John waits less than 20 minutes for the train.

To find this probability, we need to calculate the area under the density curve from 0 to 20:

P(X < 20) = ∫[0,20] (1/30) dx

P(X < 20) = [x/30] from 0 to 20

P(X < 20) = 20/30 - 0/30

P(X < 20) = 2/3

The correct answer is option b. 15.77%. The annual discount rate, also known as the discount rate or the rate of return, can be calculated using the present value formula.

Given that a cash flow of £52 million in 5 years' time is currently valued at £25 million, we can use this information to solve for the discount rate.

The present value formula is given by PV = CF / (1 + r)^n, where PV is the present value, CF is the cash flow, r is the discount rate, and n is the number of years.

In this case, we have PV = £25 million, CF = £52 million, and n = 5. Substituting these values into the formula, we can solve for r:

£25 million = £52 million / (1 + r)^5.

Dividing both sides by £52 million and taking the fifth root, we have:

(1 + r)^5 = 25/52.

Taking the fifth root of both sides, we get:

1 + r = (25/52)^(1/5).

Subtracting 1 from both sides, we obtain:

r = (25/52)^(1/5) - 1.

Calculating this value, we find that r is approximately 0.1577, or 15.77%. Therefore, the annual discount rate is approximately 15.77%, corresponding to option b.

The equation log(8x+2) = 3 can be rewritten in exponential form as 10^3 = 8x+2. Simplifying, we get:

1000 = 8x + 2

998 = 8x

x = 124.75

Therefore, the solution to the equation is x = 124.75, which is an approximation to 3-decimal places.

To verify the solution, we can substitute x = 124.75 back into the original equation and check if both sides are equal:

log(8(124.75) + 2) = log(1000)

log(1000) = 3

Since both sides are equal, we can conclude that x = 124.75 is indeed the solution to the equation.

Note that it is important to check the solution obtained from solving the equation as sometimes the solution may not be valid due to the domain of the function involved in the equation.

The surface area of a solid cannot be determined without knowing its shape and dimensions. Assuming the given dimensions refer to a rectangular prism, we can use the formula for the surface area of a rectangular prism to calculate the surface area.

To find the surface area of a solid with given dimensions of 367 ft and 14 ft, we need to first determine the shape of the solid. Without this information, it is impossible to calculate the surface area. Assuming the given dimensions refer to a rectangular prism, we can use the formula for the surface area of a rectangular prism which is:
SA = 2lw + 2lh + 2wh
where SA represents the surface area, l represents the length, w represents the width and h represents the height.
Substituting the given values into the formula, we get:
SA = 2(367 x 14) + 2(367 x h) + 2(14 x h)
Simplifying this equation, we get:
SA = 10276 + 734h
where h represents the height of the rectangular prism.
Without knowing the height of the solid, it is impossible to calculate the exact surface area. However, we can say that as the height increases, so does the surface area. Therefore, the larger the height of the rectangular prism, the greater the surface area.
In conclusion, the surface area of a solid cannot be determined without knowing its shape and dimensions. Assuming the given dimensions refer to a rectangular prism, we can use the formula for the surface area of a rectangular prism to calculate the surface area.
