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.
the source would be the centre of your circle which is (-6,-4) and the range would be the radius of your circle which is √36 or 6
both are right. here is my answer.
The source would be the center of the circle. Knowing this, we can say that the source of the signal is at (-6,-4). The radius, also known as the range in this problem, is the square root of 36, or 6.
