Steve kicks a football into the air. The path that the ball takes can be described by the equation h=20t-5t² where h is the height of the ball in meters and t is time in seconds. Answer the following questions:

1. how high is the ball after 3 seconds?

2. After how many seconds will the ball be 15 meters high?

3. After how many seconds will the ball be 25 meters high?

4. when will the ball hit the ground?
​

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

good job you smart son of a gun you are smarter that einstein. 7
