How to identify the source and range of the signal?

Remember that a circle of radius R, centered at the point (a, b) is described by the equation:

[tex](x - a)^2 + (y - b)^2 = R^2[/tex]

In this case, we have the equation:

[tex](x - 5)^2 + (y + 2)^2 = 49[/tex]

First, notice that 49 = 7², so we can rewrite:

[tex](x - 5)^2 + (y + 2)^2 = 7^2[/tex]

Then, comparing this with the general circle equation, we can see that the center is at (5, -2) and the radius is R = 7.

Then the source is at (5, -2) and the range is 7 units.
