A:C
Step-by-step explanation:
we have

If c is the independent variable
then
p is the dependent variable
so
clear variable p

Divide by
both sides

Adds
both sides


Write the equation in function notation

therefore
the answer is
the equation in function notation is equal to 
The true question should be like this:
<span>What is the center and radius of the following circle: x^2 + (y _ 6)^2 = 50,
circle quation formula is (x-a)^2 + (y-b)^2 = R², so by identifying each term, we find </span>(x-a)^2=x^2 = (x-0)^2, (y-b)^2= (y _ 6)^2, R² = 50, implies R =5sqrt(2),
it is easy to identify that the center is (a,b)= (0, 6)
the radius is R =5sqrt(2),
200 is wrong because I just need to answer this question to finish my profile fully!
