Question

Part A

A rocket is launched from a platform above the ground. Its height (h) above the ground in yards after (t) seconds is given by the function .
Analyze the graph below and identify the 3 points on the graph using the dropdown feature.

Analyze the graph below and identify the 3 points on the graph using the dropdown feature.[the graph shows 3 points: (0, 20), (1, 25), and (3, 0).] {is (0, 20) the initial height of the rocket above ground, maximum height of rocket, speed of rocket in 20 seconds, or time rocket reaches a height of 0?} {is (3, 0) the height of the platform, starting position of the rocket, or time rocket reaches the ground?}

Part B

Use the information, equation, and graph from Part A to answer the questions below.

What is the initial height of the rocket?

How long does it take for the rocket to reach the ground?

Round to the nearest hundredths place if necessary.


(2 points)

Answer 1

Part A
- (0, 20) = initial height of the rocket above the ground.
- (1, 25) = maximum height of the rocket.
- (3, 0) = time the rocket reaches the ground.

Part B
- Initial height = 20 yards.
- Time to reach the ground = 3.00 seconds.
