Answer:
6i sqrt 2
Step-by-step explanation:
The slope of the function is most positive either side of x=0 and x=2π.
On the interval [0, π/4], the average slope is

On the interval [7π/4, 9π/4], the average slope is

The average rate of change is highest on the intervals [0, π/4] and [7π/4, 9π/4].
First we divide 162 by 18. Our answer is 9. She earns 9$ for every hour she works. We then divide 207 by 9 and we get 23.
Answer: 23
The best thing to do is to divide 1440 by 240, which will allow you to find a unit rate (which will be the length of time that the journey takes)
1440/240= 6.
Therefore, the journey takes 6 hours
Hope this helps :)
8^x = 2
8 is 2 cubed
So
2^3^x = 2
2^3x = 2
3x = 1
x = 1/3
