Answer:
114°
Step-by-step explanation:
The measure of an arc is double the measure of the angle between the chord and the tangent line.
To shift a graph down by two units, -2 must beg added to the function.
Since g(x)=0.5x-k already, k=2, because it is already specified that the constant will be subtracted.
The segments above the bisector are proportional to the corresponding segments below.
(4x +1)/5 = 15/3
4x +1 = 25
x = (25 -1)/4 = 6
The value of x is 6.
For this case, we must find the equation of the line.
The generic equation of the line is:

The slope of the line is:

Substituting values we have:

Rewriting:

We now choose an ordered pair:
(xo, yo) = (0, 12)
Substituting values we have:

Rewriting the equation:

For 20 visits, we evaluate the equation when x = 20.
We have then:
Answer:
The discounted entrance fee is 1.5$. The total cost is 42$ after 20 visits
