The height, h, in meters above ground, of a projectile at any time, t, in seconds, after the launch is defined by the function h(t) = −4t^2 + 19t + 5. The graph is shown below. When rounded to the nearest tenth, what is the maximum height reached by the projectile, how long did it take to reach its maximum height, and when did the projectile hit the ground? The projectile reached a maximum height of 27.6 meters in 2.4 seconds and it took 5.0 seconds for it to hit the ground.
