Not too sure about this one

elena-s [515]

Answer:

see explanation

Step-by-step explanation:

let y = f(x), then

y = 11x - 1

Interchange x and y and solve for y

x = 11y - 1 ( add 1 to both sides )

x + 1 = 11y ( divide both sides by 11 )

y = $\frac{x+1}{11}$ , hence

$f^{-1}$ (x) = $\frac{x+1}{11}$

Ryan wanted to know the height of a cell-phone tower neighboring his property he walked 80 feet from the base of the tower and m

spin [16.1K]

Since Ryan is 5 feet tall, we will assume that the height of the cell-phone tower is x + 5.
Since the given is 54 degrees.
Tan 54degrees = x/80(feet)
x=80(tan54)
x=110
To finalize the answer, we will add up the height of the cell-phone tower to the answer.
110 + 5 = 115 feet
So the answer to the question is that the height of the cell-phone tower is 115 ft.
