SOLUTION: The flight of a baseball that has been hit when it was 4 feet off the ground is modeled by the function h = -16t (to the 2nd power) + 75t + 4 where h is the height of the baseball

Question 613032: The flight of a baseball that has been hit when it was 4 feet off the ground is modeled by the function h = -16t (to the 2nd power) + 75t + 4 where h is the height of the baseball in feet after t seconds. Rounding to the nearest hundredth, how long will it take before the ball lands on the ground? (Please show your work)

on the ground is h=0

0 = -16t^2 + 75t + 4

use the quadratic formula to find the solution (you want the positive one)
