Calculate the height of the rocket 3 seconds after it was launched.
h=-5t^2+23t+10

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

After t seconds, a ball tossed in the air from the ground level reaches a height of h feet given by the equation h = 144t-16t^2. after how many seconds will the ball hit the ground before rebounding?

Based on the diagram, match the trigonometric ratios with the corresponding ratios of the sides of the triangle. tiles : cosb sinb tanb sincposs matches: c/b b/a b/c c/a
