12. Two runners are 100 ft. apart. On a signal, they run to a flag on the ground midway between them. The faster runner hesitates for 0.1 sec. The following parametric equations model the race to the flag:
x1= 10(t-.01), y1=3
x2= 100-9t, y2=3
Use your graphing calculator to simulate the race. Based on this simulation, runner (x1/y1) wins the race. (6.3, #38)
a. true
b. false
13. A man hits a baseball when it is 4 ft. above the ground with an initial velocity of 120 ft/sec. The ball leaves the bat at a 30 degree angle with the horizontal and heads towards the 30 ft. fence 350 ft. away from home plate. The ball will not clear the fence. (6.3, #44)
a. true
b. false
