No,   and are not inverses of each other.

Step-by-step explanation:

Given functions:

To tell whether and are inverse of each other.

Solution:

If   and are inverse of each other, then:

  or  

Thus, to check if they are inverse of each other, we will find inverse of function and see if it is =

We have:

In order to find inverse we will replace with

Then we switch and

Then, we solve for

Subtracting both sides by 4.

Multiplying both sides by 2.

Using distribution:

Dividing both sides by -3.

Thus inverse of function can be given as:

Since , hence they are not inverse functions of each other.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

the answer is 13 cm
