Select the correct answer.
a baseball is thrown into the air from the top of a 224-foot tall building. the baseball's approximate height over time can be represented by the quadratic equation h(t) = -16t2 + 80t + 224, where t represents the time in seconds that the baseball has been in the air and h(t) represents the baseball's height in feet. when factored, this equation is h(t) = -16(t - 7)(t + 2).
what is a reasonable time for it to take the baseball to land on the ground?
a.
7 seconds
b.
2 seconds
c.
9 seconds
d.
5 seconds
