Evaluate the expression w^2 - v + 1 for w = -2 and v = -8
a. -3
b. -11
c. 13
d. 5

I think the answer is C. 13.

Step-by-step explanation:

(-2)^2-(-8)+1

4+8+1

12+1

13

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
