Lina20 [59]

Answer:

2 and 4.

Step-by-step explanation:

(x+2)^2 - x^2 = 12

x^2 + 4x + 4 - x^2 = 12

4x + 4 = 12

4x = 8

x = 2.

Hence the integers are 2 and 4.

A company has fixed monthly costs of $130,000 and production costs on its product of $32 per unit. The company sells its product
Svet_ta [14]

Answer:

The cost function is C(x)=32x+130000.

The revenue function is R(x)=66x.

The profit function is P(x)=34x-130000.

Step-by-step explanation:

We have the following definitions:

The cost function is a mathematical formula that gives the total cost to produce a certain number of units. It consists of variable costs and fixed costs and is given by

C(x)=(fixed \:cost)+x\cdot (variable \:cost)

If x units are sold and the price per unit is p(x), then the total revenue is

R(x)=x\cdot p(x)

and R(x) is called the revenue function.

If x units are sold, then the total profit is

P(x)=R(x)-C(x)

and P(x) is called the profit function.

Applying the above definitions we get that:

We know that the company has fixed monthly costs of $130,000 and production costs on its product of $32 per unit.

Therefore,

The cost function is C(x)=32x+130000.

We know that the company sells its product for $66 per unit.

Therefore,

The revenue function is R(x)=66x.

The profit function is

P(x)=R(x)-C(x)\\P(x)=66x-(32x+130000)\\P(x)=34x-130000

If Janet scored an 85% on her test she answered 34 questions correctly how many questions were on the test
Wittaler [7]
40 questions. You set up a proportion, mutiply 34 by a 100 and get 3400. Then you divide 3400 by 85 and you get ur answer. You could also try guessing by putting in random values you think are the whole number and multiplying them by 0.85. So if you guess 44 is the whole and try checking it by multiplying it by .85 and get a value thats higher than the value the percentage is equal to you try another smaller value. So if 44 doesn't work you can try 40. 40 times .85 is 34 so your answer of 40 questions is correct.

9514 1404 393

Answer:

  27.932 in

Step-by-step explanation:

The initial angle (or height) is not shown, so we have assumed it is 30°. The equation for the height of the valve cap can be written as a function of angle:

  y = 15.375 +14.5·sin(x +30) . . . . . . where x is in degrees

The angle measured from the +x axis is already 30° when the rotation angle is zero. Evaluating the above equation with x = 390° gives an angle of 420°, or 60° beyond one full rotation.

  y = 15.375 +14.5·sin(60°) ≈ 27.932 . . . . inches above the ground.

The valve cap is 27.932 in. above the ground.
