Question

A toy rocket was shot into the air. The graph below represents the height over the time of the rocket. Which of the following are true? Select all that apply.
A. The rocket was launched from a platform 4.9 feet above the ground

B. The rocket reached a maximum height of 59 feet

C. It took the rocket 3.5 seconds to reach its maximum height

D. The rocket landed after 34 seconds

E. The equation that represents the rocket’s height over time has two solutions

Answer 1

Answer: Option 'B' and 'C' are correct.

Step-by-step explanation:

Since we have given that

A  rocket was fired into the air.

The rocket reached a maximum height of 59 feet at point (3.5,59) as shown in the figure.

And it took the rocket 3.5 seconds to reach its maximum height.

and the rocket landed after 6.9 seconds, So option 'D' is false which states  The rocket landed after 34 seconds.

The equation that represents the rocket’s height over time has two solutions is completely false as it has only one solutions.

Hence, Option 'B' and 'C' are correct.

Answer 2

Answer:

OH MY GOD CAN THE VERIFIED ANSWERS BE THIS BAD. I swear every verified answer I've been getting on this site have been incomplete or totally wrong, and you can't even report it because it is a verified person making the answer......... anyway I took the test yourself test and got this question wrong because this verified answer says that b and c are correct, which is true but so is e. I can't believe that they would make an incomplete answer and get people confused... Anyway once again, the answers for the question are B, C and E. I REPEAT, B, C AND E.

Step-by-step explanation:

EVERYONE DOWNVOTE THE VERIFIED ANSWER SO WE CAN SHOW THE PEOPLE THAT THE VERIFIED ANSWER IS INCOMPLETE. DON'T LET ANYBODY ELSE BE TRICKED INTO GETTING THE INCOMPLETE ANSWER!!!

Review Question #3:

1.) False - The rocket was launched from a platform 4.9 feet above the ground.

This is false because on the graph it shows that it started at 0 feet.

2.) True - The rocket reached a maximum height of 59 feet.

This is true because it shows on the graph that the rockets highest point was at 59 feet.

3.) True - It took the rocket 3.5 seconds to reach its maximum height.

This is true because it shows on the graph where the rocket hits it’s maximum height that it hit that point in 3.5 seconds.

4.) False - The rocket landed after 34 seconds.

This is false because it clearly shows on the graph that the rocket landed a little bit before 7 seconds after take-off.

5.) True - The equation that represents the rocket’s height over time has two solutions.

This is true because there are two points on the graph which shows when the rocket lands and when it is at its highest point.
