Answer:
2
Step-by-step explanation:
The average rate of change from x=1 to x=2 is the same as finding the slope of a line at x=1 and x=2.
So we are going to need to corresponding y coordinates.
What y corresponds to x=1? y=3
What y corresponds to x=2? y=5
So we have the ordered pairs (1,3) and (2,5).
Line the points up vertically and subtract vertically then put 2nd difference over 1st difference.
(2 , 5)
-(1 , 3)
-----------
1 2
The average rate of change is 2/1 or just 2.
Now since we were asked to find the average rate of change given the function was a line, it really didn't matter what two points you used on that line.
Answer:
49 1/6 meters
Step-by-step explanation:
P = 2(73/3) + 2(61/4)
= 146/3 + 61/2
= 48 2/3 + 30 1/2
= 48 4/6 + 30 3/6
= 48 + 7/6
= 48 + 1 1/6
= 49 1/6
