Aquarterback 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?

Indicated here when h(t) = 0, we are to find for the time where the football has reached a certain height. 

Then, the values of t would be -0.2 and 2.7.

Since we are to look for the time, it is impossible for us to have an answer that has a negative value. So based from our answer, the solution that we will eliminate is the -0.2 one. Since its value is negative.

So, the correct value would be the 2.7 sec. one.
