A toy rocket is fired from the top of a hill. Its height above the ground can be modeled by the function y=-16x² +96x +112, where x measures time in seconds and y measures the height, in feet, above the
ground.
a.
Find the greatest height the rocket reaches before it lands on the ground.
b. Find the time at which the rocket lands on the ground.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

a.)the line for function b is steeper

i would be 2,000 just get the square root of 50 which is 2500 and the divid 4/5 and last thing multiply the answer you get for that by the square root of 50
