Question

help pls ....

Answer 1

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 ℎ 𝑥 =
−4.9𝑥2 + 21.3𝑥. About how many seconds will it take for the ball to hit the ground?

Answer 2

Answer 3

area = length*width and perimeter = 2(length+width)

154 = l*w, by dividing both sides by l
154/l = w

h(x) = −4.9𝑥2 + 21.3𝑥

ball is on the ground, h(x) = 0 (height = 0)
h(x) = 0 and for x

Answer 4

@freckles will I put 0 in the places of the x?

Answer 5

no in place of h(x)

Answer 6

hmmm.. what happened to the other question
