On a coordinate plane, the center of circle P is at the point (2,15). Point M is located on the circle at (7,3). Which equation describes circle P?

A. (x+2)^2+(y+15)^2=13
B. (x-2)^2+(y-15)^2=13
C. (x+2)^2+(y+15)^2=169
D. (x-2+)^2+(y-15)^2=169

i dont know sorry

step-by-step explanation:

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
