A ball is thrown, and the height (in meters) as a function of time (in seconds) is h = -5t2 + 20t + 2.

For how many seconds was the height of the ball at least 17 meters?

How long was the ball in the air?

Two parallel lines are crossed by a transversal.what is value of x

The reflexive property of congruence lets you say that ∠pqr ≅

Someone answer asap for ! a ball is rolled down a ramp. the height, f(x), in meters, of the ball x seconds after it is released is modeled by the function f(x) = x²- 10x + 25 for all values of x from 0 to 5. which statement about the ball is true? a. the maximum height of the ball is 5 meters b. the height of the ball increases from 0 to 5 meters above the ground. c. the ball has traveled 5 meters when it reaches the bottom of the ramp. d. the ball has been traveling for 5 seconds when it reaches the bottom of the ramp
