A quarterback throws an incomplete pass. The height of the football at time t is modeled by the equation h(t) = –16t2 + 40t + 7. Rounded to the nearest tenth, the solutions to the equation when h(t) = 0 feet are –0.2 s and 2.7 s. Which solution can be eliminated and why?
The solution –0.2 s can be eliminated because time cannot be a negative value.
The solution –0.2 s can be eliminated because the pass was not thrown backward.
The solution 2.7 s can be eliminated because the pass was thrown backward.
The solution 2.7 s can be eliminated because a ball cannot be in the air for that long due to gravity.
