15 Points all I have left please help.
The function f(t) = −16t^2+ 80t + 5 represents the height (in feet) of
the first water balloon t seconds after it is launched. The height of
the second water balloon t seconds after it is launched is shown in
the graph. Which balloon is in the air longer? Explain your reasoning.
Which balloon reaches its maximum height faster? Explain your
reasoning.

The second water balloon is in the air longer. Balloon 1 will reach the maximum height faster because it is lower.

Step-by-step explanation:

This is because you drop the first balloon at a height of 105 ft. The second balloon is dropped at a height of 125 ft. The second balloon stays in the air longer because it was dropped at a higher elevation. Balloon 1 will reach the maximum height faster because it is lower.

If this answer is correct, please make me Brainliest!

On my graph, the black line is the equation for Balloon 1 and the red line is the equation for Balloon 2. Since the black line has a lower maximum, this means that Balloon 1 will reach its maximum first.

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

the answer is 13 cm
