I am offering 20 points for this question since it SEEMS hard and i kinda need help to get this right ( awesome over-the-spring-break homework in Hawaii)
This is the the equation of a circle in the xy plane is shown below. What is the radius of the circle?

2

Step-by-step explanation:

The center-radius form of the circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being "r". This form of the equation is helpful, since you can easily find the center and the radius.

3x^3-x^2+6x-9

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i
