Find the center and radius of the circle whose equation is given below: (x − 2.5)2 + (y + 5.4)2 = 1.21

The center is at (2.5, -5.4)  and the radius is 1.1

Step-by-step explanation:

The formula for a circle is

(x-h)^2 + (y-k)^2 = r^2

Where (x,k) is the center and r is the radius)

(x − 2.5)^2 + (y + 5.4)^2 = 1.21

(x − 2.5)^2 + (y -  - 5.4)^2 = 1.1^2

The center is at (2.5, -5.4)  and the radius is 1.1

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
