Step-by-step explanation:
Answer:
The average rate of change

At t = 1

at t=3
Step-by-step explanation:
<u><em>Step(I)</em></u>:-
The given function h(t) = 3+70t - 16t²

The
70 - 32 t = 0
⇒ 70 = 32 t
⇒ 
<em>Step(ii</em>):-
The average rate of change in h(t) between t = 1 second and t = 3 second

At t = 1

At t = 3
100/2 = 50
I think the answer is 50.
I hope this helps! :D
In every triangle, all the measures of the angles combined is 180 degrees.
So x + y + z = 180 degrees
