12) A model for an object launched directly into the air is h(t) = -16t+64t + 80, where t is the time in seconds and h is the height in feet. Round all answers to three decimal places.

What is the maximum height of the object?

a.

b. After how many seconds does the object reach its maximum?

c.

How many seconds will it take the object to reach the ground after its initial launch? I

jml angle lkj & angle mj = lm

they charge the same amount at 20 minutes.

step-by-step explanation:

i will u if u answer my question in math

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
