Question

MEDALSSS!!!!
13. A ball is thrown into the air. The height in feet of the ball can be modeled by the equation h = -16t2 + 20t + 6 where t is the time in seconds, the ball is in the air. When will the ball hit the ground? How high will the ball go?

Answer 1

Answer 2

If h is the height then to determine the number of seconds until it hits the ground you need to make h = 0 an solve quadratically.

Answer 3

ok i got that

Answer 4

so how do i get the answer

Answer 5

Do you know the quadratic equation?

Answer 6

yess

Answer 7

So make h =0 in the original equation and solve. The result must be positive. See what answer you get and then we will address the height question.

Answer 8

ok

Answer 9

16^2 is wat??

Answer 10

nvm
