1. [-/6 Points] DETAILS SCALCET9 2.1.001.MI. Q (5, 2,076) A tank holds 3,000 gallons of water, which drains from the bottom of the tank in half an hour. The values in the table show the volume V of water remaining in the tank (in gallons) after t minutes. t (min) 5 V (gal) (a) If P is the point (15, 735) on the graph of V, find the slopes of the secant lines PQ when Q is the point on the graph with t= 5, 10, 20, 25, and 30.
