Answer: she applied the reflection to the triangle first
&
she changed the size of the triangle instead of just applying a translation.
Step-by-step explanation:
Answer:
It's the 3rd answer choice
The equation of circle with the center at (h,k) is:

r stands for radius. Therefore r^2 = diameter or 2×radius.
The question has already given the information we need, which are:
- radius = 4
- the center at (0,8)
Since the center is (h,k) - therefore the center is at h = 0 and k = 8 making it (h,k) = (0,8).
Substitute the values in the equation:

Simplify to the simplest form

Answer
- The equation of a circle is x^2+(y-8)^2 = 16
