Answer:

Step-by-step explanation:
Given

Required
The inverse

Replace f(n) with y

Swap positions of y and n

Make y the subject

Replace y with f'(n)

The independent variable are the length and width while the dependent is the area.
See the attached picture to better understand the problem
we know that
in the right triangle ABC
cos 70=adjacent side angle 70/hypotenuse
adjacent side angle 70=BC----> <span>distance between the ladder and the tree trunk
hypotenuse=AC------> 15 ft
cos 70=BC/AC-------> solve for BC
BC=AC*cos 70------> BC=15*cos 70-----> BC=5.13 ft
the answer isthe </span>
distance between the ladder and the tree is 5.13 ft<span>
</span>
