Name each raycalculation tip: in ray "ab", a is the endpoint of the ray.

If the endpoints of the diameter of a circle are (8, 6) and (2,0), what is the standard form equation of the circle? a) (x + 5)2 + (y + 3)2 = 18 (x + 5)2 + (y + 3)2 = 3.72 (x - 5)2 + (y - 3)2 = 18 d) (x - 5)2 + (y - 3)2 = 32

If f(x)=x+7 and g(x)=1/x what is (fog)(x)
