c. Solve D(C(x)) = 10 d. Solve C(D(p)) = 10 32. The function S(h) gives the sleep level on a scale of 0-10 experienced by a person with h hours of sleep without exercise. The amount of sleep of the person after t minutes of exercise is modeled by e(t). To determine when the patient will be at a sleep level of 8, you would need to: a. Evaluate S(e(8)) b. Evaluate e (S(8)) c. Solve S(e(t) = 8 d. Solve e(s(h) = 8 13V 3. The radius r, in inches, of a basketball is related to the volume, V, by r(V) = Air 4 TC pumped into the basketball, so the volume after t seconds is given by V (t) =12+18t . a. Find the composite function r (V (t)) b. Find the time when the radius reaches 9 inches
