Sarah kicked a soccer ball into the air with an initial upward velocity of 48 feet

per second. The height in feet of the ball above the ground can be modeled by h = –16t^2 + 48t , where t is the time in seconds after Sarah kicked the ball.

a. How long was the ball in the air before it returned to the ground?
b. Find the height of the ball after 2 seconds.

The graph of which equation includes the points (0, 10) and (10, 11)? y = 10x + 11 y = x + 10 y= 1/10x + 10 y = 1/10x + 11
