Using it's concept, it is found that the average rate of change of the function during the interval from 0 to 2 seconds is given by:
B. -32 ft/s; the average change in altitude of the ball each second over that interval.
<h3>What is the average rate of change of a function?</h3>
The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:
In this problem, the function is given by:
f(t) = -16t² + 100.
The outputs are given as follows:
- f(0) = -16(0)² + 100 = 100.
- f(0) = -16(2)² + 100 = 36.
Hence the average rate of change is given by:
r = (36 - 100)/(2 - 0) = -32 ft/s.
And the correct option is:
B. -32 ft/s; the average change in altitude of the ball each second over that interval.

0.5 (5-7x) = 8 - (4x+6)
2.5 -3.5x = 2 -4x
2.5 - 2 = -4x + 3.5x
.5 = - .5x
multiply 2 on both sides
1 = -x
change the x into positive
x = -1
now to check answer
0.5 [5-7(-1)] = 8 - [4(-1) + 6]
0.5(5+7) = 8 - (-4+6)
0.5(12) = 8 - 2
6 = 6
Hope this helps
Answer:
We get
Step-by-step explanation:
We know that there's a worker he works 10 hours each day for 14 days. Therefore, he works total 140 hours.
We know that: the big pieces cost 25 to make n 6 hrs to finish
and little ones cost 15 n 2 hrs to finish.
We conclude that he can make 10 the big pieces for 60 hours and he can make 40 the little ones for 80 hours. Threfore, he works 60+80=140 hours.
