2. Find AC. Show your work I Write your answer in the space below.

The length of AC = 25

Step-by-step explanation:

Triangle ABD is a right triangle and can use the Pythagorean theorem which is + =

one leg is BD = a = 12

hypothenuse is BA = c = 15

other leg is AD = b, which we need to find

+ =

= -

= -

= 225 - 144

= 81

b = leg AD = 9

The length of AC = AD + 16 (given in picture) = 9 + 16 = 25

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
