Answer:
the center is (-2,2) and the radius is 5
Answer:
C
Step-by-step explanation:
The trig equation

where d represent the midline.
D is represented by positive 1 so y=1 is the midline.
We have to simplify the expression here. The expression given,

Now to find
we will use power of a product property. We have to distribute the power here. We will get,

= 
Now we will use power of a power property. If given
we will have to multtiply the powers and we will get
. So we will get here,

Now the next part is 
By using power of a power property we will get,

Now we have to multiply them.

Now we have to use product of powers property. If we have same base them we will have to add the exponents there. The formula is
. So we will get here,


So we have got the required simplified answer here.
The simplified answer is
.
