    8. Stephanie is a very good soccer player. She can kick a soccer ball with an initial velocity of 21.3 m/sec. The function that represents the height of the ball with respect to time is β„Ž π‘₯ = βˆ’4.9π‘₯2 + 21.3π‘₯. About how many seconds will it take for the ball to hit the ground?

    area = length*width and perimeter = 2(length+width) 154 = l*w, by dividing both sides by l 154/l = w h(x) = βˆ’4.9π‘₯2 + 21.3π‘₯ ball is on the ground, h(x) = 0 (height = 0) h(x) = 0 and for x
