You need the Law of Cosines here and you use it when you have 2 sides and an enclosed angle. The side across from the angle is the one we are looking for. The correct way to express the Law using what we have is the last choice above. Side RT is the unknown, and it is across from the angle that is enclosed between the 2 other sides.

Find the break-even point for the given cost and revenue equations. Round to the nearest whole unit.. C = 20n + 134,000. R = 160

Novay_Z [31]

The break-even point is when there is no profit and no loss. Given the two equations for cost and revenue, we simply have to equate the two equations to solve for the unknown value, n. This is shown below:

C = 20n + 134000
R = 160n

R = C
160n = 20n + 134000
140n = 134000
n = 957.14

Among the choices, the nearest answer is D. 957.

The price of a mango at a fruit stand goes up 5 cents each month. The first month the stand was open, a mango cost $1.25. What w

Dahasolnce [82]

Answer:

$2.45

Step-by-step explanation:

Let x be the number of months.

We have been given that price of a mango at a fruit stand goes up 5 cents each month. This means that price of mango in dollars after x months will be 0.05x (1 dollar=100 cents).

The first month the stand was open, a mango cost $1.25. This means that cost of mango in the x months after 1st month will be: $1.25+0.05x$
