A toy rocket was shot into the air. The graph below represents the height over the time of the rocket. Which of the following ar
Ludmilka [50]

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.

Dahasolnce [82]

Answer:

11.5 square units

Step-by-step explanation:

It’s a 4 by 6 rectangle, so the total is 24.  Then subtract the three little triangles on the outside.  (Much easier than doing the main triangle).

1/2x1x4=2

1/2x1x6=3

1/2x3x5=7.5

2+3+7.5=12.5

24-12.5=11.5
