The answer to this is 73 degrees.
Answer:
x = 10 and x = -10
Step-by-step explanation:
Given the function

This function is undefied when the denominator equals to 0. Find these values for x:

This means that vertical lines x = 10 and x = -10 are vertical asymptotes (the graph of the function f(x) cannot meet these lines because this function is undefined at x = 10 and x = -10)
I I think you have the correct answer!
Answer:
The radius is 12.
Step-by-step explanation:
You're given the center and a point on the circle. The point and the center both have an x-coordinate of -5, so there is no horizontal distance between them. The distance is only in the vertical direction. The distance from 8 to -4 is 12. Since this is the distance from the center to a point on the circle, this equals the radius.
