Assuming that by "16t2" you mean
:
First of all, let's compute the position at the two required times:


So, the ball traveled a total distance of
, during the time
.
The average rate of change is the ratio between these two:

Answer: A
Step-by-step explanation:
48, 56, 68, 72, 72, 78, 78, 80, 82, 84, 88, 88, 88, 90, 94, 98, 100

Answer:
52
Step-by-step explanation:
Range is the largest value minus the smallest value
100 - 48 = 52
You are looking for the average. To find the average, one adds all terms and divides by the number of terms.
((1/2)+(5/6))/2
((3/6)+(5/6))/2
(8/6)/2
(4/6)
(2/3)
The answer is B) 2/3.
The value for x is 9 because:
7x +49 = 2x + 94
7x-2x=45
5x=45
x=45/5
x=9
