Given:
Consider the given function is:

To find:
The average rate of change of the function over the interval
.
Solution:
The average rate of change of the function f(x) over the interval [a,b] is:

We have,

At
,



At
,



Now, the average rate of change of the function f(x) over the interval
is:




Therefore, the average rate of change of the function f(x) over the interval
is -3.
Answer:
We need to subtract both equations. 2x3+30x-130-2x3+3x+520
that gives
30x-130+3x + 520
33x+390
D is answer
Welp, looking at the number: 66
......
The second digit "6" is up to or more than 5.
...............
So, we can clearly round it up.
.....................
In this case, we are rounding to the nearest hundredth.
.............................
Hm, 100 is pretty close to 66.
..................................
We can now say that the nearest hundredth is 100.

Answer:
Jane: 37 years old
Anne: 17
Step-by-step explanation:
Jane 12 years ago: 5x
Anne 12 years ago: x
In three years into the future:
Jane: 5x+15
Anne: x+15
CURRENT TIME:
Jane: 5x+12
Anne: x+12
Equation (using 3 years into the future ages): 5x+15=2(x+15)
5x+15=2x+30
(subtract 15 from both sides)
5x=2x+15
3x=15
x=5
Therefore, Jane is 37 years old and Anne is 17 years old.
Negative and Positive numbers dictate direction on a graph. Negative numbers indicate the point is moving left, and positive numbers indicate the point is moving right.
