point(s) possible The function H= f(1) gives the height of the water, in inches, in a bathtub at time t, in minutes. Starting with an empty tub at t = 0, you plug the drain, take off your watch, turn on some relaxing music, enter the tub, and then begin to fill it at = 2. The height of the water rises steadily until you turn off the water at t = 7. You relax in the tub, for the next 10 minutes a. What are the units of f'(t)? b. When are both f and f' the same value? a. The units of f'(t) are b. For which of the value(s) of t are both f and f' the same value? O A. t= 1 OB. t=8 O C. t= 1 and t= 8 O D. t= 4 and t = 8 O E. 1=4
