Abaseball 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. 5 seconds d. 9 seconds
