C.
Let g(x) = y. This gives you y =
![\sqrt[3]{ \frac{x-6}{8} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7Bx-6%7D%7B8%7D%20%7D%20)
Manipulating the above equation gives you x = 8y^3 + 6 which is f(y), meaning that f(g(x)) = x so f and g are inverses of each other.
Answer:
27 miles
Step-by-step explanation:
The law of cosines can be used to find the distance between the boats. In 1 hour, one has traveled 28 miles, and the other has traveled 26 miles. The angle between their directions of travel is ...
180° -50° -70° = 60°
Then the distance c can be found from ...
c^2 = a^2 +b^2 -2ab·cos(C)
c^2 = 28^2 +26^2 -2·28·26·cos(60°) = 732
c = √732 ≈ 27.055
The boats are 27 miles apart after 1 hour.
