What is the standard form of the equation of a circle that has its center at (2, -3) and passes through the point (2,0)? O A (x + 2)2 + (x+3)2 = 9 OB (x - 2)2 + (y - 3)2 = 16 OC. (x - 2)2 + (y - 3)2 = 4 OD. (x + 2)2 + (x + 3)2 = 16 O E. (x - 2)2 + (y + 3)2 = 9 ​

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:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
