Question 1194987: I need help with these math problems please thank you!
D. A football is kicked straight up into the air. Its height above the ground is approximated by the relation y=25x-5x^2, where y is the height of the ball in meters and x is the time in seconds. There are two times when the football is 27.5m in the air, on the way up and on the way down. Joe realizes that using the equation y=27.5, he can determine the two times the ball is 27.5 meters in the air. Algebraically or graphically determine these two times?
