Answer:
x = 39
Step-by-step explanation:
We know that PRQ is a right triangle, so we use the pythagorean theorem to solve the problem. The theorem states that a^2 + b^2 = c^2. Let's assume that the length of RP is c, the length of PQ is a and x is b. We plug the lengths into the equation and solve it:
80^2 + x^2 = 89^2
6400 +x^2 = 7921
x^2 = 1521
x =
x = 39

EXPLANATION
The revenue function is
The cost function is,
C=600-50t
In order to break even, revenue must be equal to cost.
Group every term on the LHS.
Divide through by 50.
Factor to obtain,
Answer:
11.1
Step-by-step explanation:
To find the side measurement we have to use trig, and the trig function Cosine, or cos. We use the because cosθ=. So cosθ=
, then to isolate x multiply both sides by 15. Now we have 15cos42=x, plugging this into the equation we get that x=11.1
