Answer:

C

Step-by-step explanation:

So we have the function:

h(t)=120t-16t^2

Where h(t) measures the height after t seconds.

To find the height of the object after 6 seconds, substitute 6 for t. So:

h(t)=120(6)-16(6)^2

Evaluate. Square:

h(t)=120(6)-16(36)

Multiply:

h(6)=720-576

Subtract:

h(6)=144

So, the height after six seconds of the object is 144 ft.

Our answer is C.
