Luis, using appropriate safety precautions, fires a .22 caliber gun directly into the sky above him. The bullet travels at a spe
Tanya [424]

The equation represents height as a function of time.

The bullet was in the air for 75 seconds.

The equation is given as:

h(t) = -16t^2  + 1200t

The time spent in the air is the time it takes the bullet to land on the ground.

When the bullet is on the ground, the height is:

h(t) = 0

So, we have:

h(t) = -16t^2  + 1200t

-16t^2 + 1200t = 0

Factor out t

t(-16t + 1200) = 0

Split

t = 0 or -16t + 1200 = 0

t = 0 represents when the shot is fired.

So, we solve for t in -16t + 1200 = 0

Collect like terms

16t = 1200

Divide both sides by 16

t = 75

Hence, the bullet was in the air for 75 seconds
