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???
1 answer
The center of the circle is at (-6, -4), which is the position of the source of the radio signal. The radius of the circle is 6, which means the range of the signals is up to 6 units in any direction from the source.
