I think you have to divide 275/5 and that will give you his speed for one hour.

Step-by-step explanation:
Since this is a test/hw, I'll give a hint.
This problem at first can seem a bit difficult with q's and power's everywhere.
But let's take a step backward. A power is when your mutiplying something by itself again and again.
Ex: 3^3=3 times 3 times 3
But what if we had something liiiike this:
(3^3)2
In this case its now
(3 times 3 times 3)^2, so its "techinicaly" (27)^2. And you would a fairly large number, which I'm to lazy to solve. But that's not the point.
We've seen what a power is deconstructed, and what a power is. Because my explantion probably confused you more than it helped, I'll give an example.
(2^2)^2=(2 times 2)^2=(4^2=16=2^4
However, there is a shorter way to solve it.
(2^2)^2=2^(2 times 2)=2^4
Hope this helps.
Answer:
1. the range of f^-1(x) is {10, 20, 30}.
2. the graph of f^-1(x) will include the point (0, 3)
3. n = 8
Step-by-step explanation:
1. The domain of a function is the range of its inverse, and vice versa. The range of f^-1(x) is {10, 20, 30}.
__
2. See above. The domain and range are swapped between a function and its inverse. That means function point (3, 0) will correspond to inverse function point (0, 3).

3. The n-th term of an arithmetic sequence is given by ...
an = a1 +d(n -1)
You are given a1 = 2, a12 = 211, so ...
211 = 2 + d(12 -1)
209/11 = d = 19 . . . . . solve the above equation for the common difference
Now, we can use the same equation to find n for an = 135.
135 = 2 + 19(n -1)
133/19 = n -1 . . . . . . . subtract 2, divide by 19
7 +1 = n = 8 . . . . . . . . add 1
135 is the 8th term of the sequence.
