You work for a radio station with a broadcast radius of 100 miles. On a particular coordinate plane, your station is located (15, -25), where the coordinate units of the grid represent one mile.
Which equation describes the broadcast coverage of your station?
[A]
(x+15)2 + (y – 25)2 = 100
[B]
(x + 15)2 + (y - 25)2 = 10,000
[C]
(x - 15)2 + (y + 25)2 - 10
[D]
(x - 15)2 + (y + 25)2 – 100
(x - 15)2 + (y + 25)2 = 10,000
