Divide I from both sides then subtract r from both sides, too so in the end:
R= (E-r)/I
Answer:
The expression used to represent g(x) as inverse of f(x) is 
Option B is correct.
Step-by-step explanation:
We are given:

We need to find the expression that could be used to verify g(x) is the inverse of f(x).
We know that
is inverse of function
So placing value of f(x) in g(x)

So, the expression used to represent g(x) as inverse of f(x) is 
Option B is correct.
We can also solve to prove that 

Answer:
<em>The height of the monument is 124.8 ft</em>
Step-by-step explanation:
<u>Right Triangles</u>
The ratios of the sides of a right triangle are called trigonometric ratios. The tangent ratio is defined as:

The figure attached below shows the different distances involved in the problem. We heed to find the value of h, the height from Daniel's eyes. Then we'll add it to the 6 ft where his eyes are located from the ground.
Taking the angle of 68° as a reference:

Solving for h:

Calculating:
h = 118.8 ft
The height of the monument is 118.8 ft + 6 ft = 124.8 ft
Answer:
Step-by-step explanation:
Answer:
x=146 degrees
Step-by-step explanation:
A supplementary angle is the conrisponding angle that adds to the other angle so it is 180. So 180-34= 146
