All angles in the figure at the right are right angles. what is the area of the figure? the top of the figure is 9 units and the left side of the figure is 5 units.

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).

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)
