Answer: C.  A new compound formed when nitrogen and hydrogen chemically reacted.

Explanation:

Due to the temperature increase, the atoms of both Nitrogen and Hydrogen reacted chemically with one another and formed a new compound which was still colorless but now had a strong odor as well.

This new compound is known as Ammonia with the chemical composition NH₃. It is formed when Hydrogen and Nitrogen react chemically. Ammonia is a colorless gas with a sharp strong odor.

Answer:

The average cost at a caseload of 25 attempted placements per month is 105.

Explanation:

The total cost function given in the question first correctly stated as follows:

TC = 25Q^1/2 + 2,500 ................ (1)

A caseload of 25 attempted placements implies that:

Q = 25

Substitute Q = 25 into equation (1), we have:

TC = (25 * 25^(1/2)) + 2,500 = 2,625

The average cost (AC) can now be calculated as follows:

AC = TC / Q = 2,625 / 25 = 105

Therefore, the average cost at a caseload of 25 attempted placements per month is 105.

In its third year, a project is expected to generate earnings before interest, taxes, depreciation, and amortization of $283,104
Lesechka [4]

Answer:

$195,751

Explanation:

Calculation for the project's expected operating cash flow

The first step will be to find the EBIT

using this formula

EBIT =(Earnings before interest, taxes, depreciation, and amortization -Depreciation expense)

Let plug in the formula

EBIT= 283,104 - 53,228

EBIT= 229,876

Second step is to find the NOPAT using this formula

NOPAT = EBIT(1- tax rate)

NOPAT= 229,876(1 - 0.38)

NOPAT= 142,523

Last step is to calculate for Expected Operating Cash flow

Using this formula

Operating cash flow = NOPAT + Depreciation expenses

Let plug in the formula

Operating cash flow = 142,523 + 53,228

Operating cash flow = $195,751

Therefore the project's expected operating cash flow will be $195,751
