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.

See the picture attached to better understand the problem

we know that
in the right triangle ABC
sin 70°=opposite side angle 70°/hypotenuse


in this problem
opposite side angle 70°=AB
hypotenuse=AC----> 32 ft
sin 70°=AB/32------> AB=32*sin 70°-----> AB=30.07 ----> AB=30.1 ft
