In the figure below the vertices of triangle RST are on a circle ●Line segment TS contains the center of the circle

●The perimeter of triangle RST is 24 inches

What is the circle's radius?

A. 8 in, because d=24-8 and d ÷2= R
B. 32 in because d= 24 - 8 and 2d= R
C. 20 in, because d=24-(8+6) and 2d=R
D. 5 in, because d=24-(8+6) and d÷2=R​

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

step-by-step explanation:

hope this !

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).

$320 to $405

step by step explanation:

in one day he earns between $64 and $81

therefore if he works for 5 days, he will earn between 64 x 5 to 81 x 5

= $320 to $405

the answer is z7+8/5
