The height in meters of a football that is kicked from the ground is approximated by f(x)=-5x^2 +20x, where x is the time in seconds after the ball is kicked. Find the ball's maximum height and the time it takes the ball to reach this height. Then find how long the bal is in the air

Step-by-step explanation:

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4
