Your friend tosses a ball into the air at an initial velocity of 18 feet per second. The equation h = -8t^2 + 18t + 5 models the height h of the ball t seconds after it was thrown. 1. How long was the ball in the air?

2. How high did the ball get?

3. When did the ball hit its highest point?​

Graph y ≥ -x^2 - 1. click on the graph until the correct graph appears.

Plot the intercepts to graph the equation

Solve this problem by using a 5d process or writing and solving an equation. no matter which method you use, be sure to define your variable and write an equation to represent the relationship a rectangle has a perimeter of 30 inches. its length is one less than three times its width what are the length and wodyh of the rectangle?
