Answer:
The average rate of change of the function over the interval x = 0 to x = 6 is 
.
Step-by-step explanation:
Geometrically speaking, the average rate of change (
) of the function over a given interval is determined by equation of secant line, that is:
(1)
Where:
, 
- Lower and upper bounds.
, 
- Function evaluated at lower and upper bounds.
If we know that 
, 
and 
, then the average rate of change of the function over the interval is:
The average rate of change of the function over the interval x = 0 to x = 6 is .
You will need to set up your table of values for each person.
Let x represent the months, and y for the amount of money.
For Carissa: For Louann:
x = y x = y
-- -- -- --
0 $250 0 $1230
1 $330 1 $1170
2 $410 2 $1110
3 $490 3 $1050
4 $570 4 $990
5 $650 5 $930
6 $730 6 $870
7 $810 7 $810
You could also do the equation:
80x + 250 = -60x + 1250
where you will get x=7.
Then substitute 7 to the x's in the equation which will give you $810 for each.
The answer is: It will take 7 months. Then, they will both have $810 in their accounts.
The answer for part b is 6
All you have to do is 3×5=15
then 8÷8=1 so 16 dollars
The answer is D I think. I'm not really good with math oof
