Question

The equation (x + 6)^2 + (y + 4)^2 = 36 models the position and range of the source of a radio signal. Describe the position of the source and the range of the signals.

Answer 1

it is a circle.
range is the radius and source is the center.
do you know how to bring them out of equation?

Answer 2

No :/

Answer 3

the general form of a circle is (x -h)^2 + (y = k)^2 = r^2

the centre is (h, k) and radius is r

in your question h = -6, k = -4 and r = 6

hopefully this helps...

Answer 4

@campbell_st is correct.

Answer 5

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

Answer 6

now he is more correct

Answer 7

I got it;
