Problem 79 of 7
Interpret two times 3, 7 with the same projectile height in model h(t)=-4.9t(t-10).
Using a hint is okay. It just tells the trainer to give you a little more review.

Times must be symmetric around the vertex time.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Identify the vertex time.
2. Compare each time's distance from the vertex time.
3. Interpret equal heights as symmetric rising and falling moments.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Saying the projectile stops at both times.
