Answer:
I believe the answer is D
The function is not invertible if you think of it as
because it is not injective: 
So, if we restrict the domain to the positive numbers only:
Note that the range is actually 
, so we can be more precise and write
To find the inverse, we solve the expression for x:
But since we restricted to positive values of x, the inverse is
Answer:
54
Step-by-step explanation:
If we know that Josh edits at a rate of 1/6 of a page in three minutes... then using the Unit rule... we can determine that he edits 1 whole page 6 times longer than that. By doing that... we find that Josh edits 1 page in 18 minutes. From there... we multiply the time at which it takes him to edit one page (18 minutes) by 3 (pages) to get our answer.
18 x 3 = 54
area of circle = pi x r^2
using 3.14 for pi
area = 3.14 x 15^2 = 706.5 square miles
270/360 = 0.75
706.5 * 0.75 = 529.875
rounded to nearest mile = 530 miles
