Which of the following is the equation of a circle with center Left-parenthesis 5 comma negative 2 right-parenthesis and a radius of 3?

A.

Step-by-step explanation:

(x-5)^2 +(y+ 2)^2= 9 radius

Rest of the questions...

1. A. (x-5)^2 +(y+ 2)^2= 9 radius

2. C. (x-3)^2+(y+5)^2= 64

3. A. Center =(-8,-9) radius 3

4. The equation of a circle is (x-7)^2 + y^2=225

5. A circle with center (-2,6) passes through the point (-2,10).

6. A circle with center (1,2) passes through the point (0,6).

7. Write the equation of the circle shown here.

8. C. (x-4)^2 + (y-3)^2

9. C. x^2+Y^2 = 15,81,600

10. Part B which of the following is the length of a 1 degree arc on the equator, to the nearest mile.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
