Question

The following graph models the height of a model rocket, in feet, measured over time, in seconds. A graph of a downward opening parabola. The x axis is labeled Time in seconds. The Y axis is labeled Height in feet. Points on the graph include (0, 3), (2.5, 103), and (5.04, 0).© 2018 StrongMind. Created using GeoGebra. How many seconds does it take for the rocket to reach the ground after takeoff?Enter your answer as a number, like this: 42Do not round your answer if it is a decimal.

Answer 1

Explanation:

On the graph, the y-value(s) represents the height of the rocket (in feet).

The rocket is at ground level at the point where its height is 0.

From the point shown below:

At the point (5.04, 0), the height of the rocket = 0 feet. The corresponding time is 5.04 seconds.

Therefore, the number of seconds it takes for the rocket to reach the ground after takeoff is 5.04 seconds.

Answer:

5.04 seconds
