Multiplechoice questions may continue on the next column or page – find all choices before answering. 001 10.0 points A tank holds 1000 gallons of water, which drains from the bottom of the tank in half an hour. The values in the table t (min) 5 10 15 20 25 30 V (gal) 687 438 207 187 21 show the volume, V ( t ), of water remaining in the tank (in gallons) after t minutes. If P is the point (15 , V (15)) on the graph of V as a function of time t , find the slope of the secant line PQ when Q = (25 , V (25)). 1. slope = − 2 2. slope = − 37 . 2 3. slope = − 48 4. slope = − 23 . 1 5. slope = − 18 . 6 002 10.0 points The position of a car as a function of time is given by the values in table t (seconds) 1 2 3 4 5 s (feet) 20 22 40 50 62 Find the average velocity for the time period beginning when t = 1 and lasting 2 seconds....
