Find the coordinates of the center and the measure of the radius for a circle whose equation is (x-8)^2 + (y+4)=12^2

step-by-step explanation:

how many centimeters did the level of the salsa go down by?

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
