Question

How would I do this problem? A low-wattage radio station can be heard only within a certain distance from the station. On the graph below, the circular region represents that part of the city where the station can be heard, and the center of the circle represents the location of the station. What is the equation that represents the boundary for the region where the station can be heard?

Answer 1

Describe the graph in standard circle notation with origin (-5,-1) and r=2

Answer 2

The origin is (-6, 1) isn't it?

Answer 3

yes, you are absolutely correct! 'sorry

Answer 4

Yes origin is \((-6, \color{red}{-}1)\)

Answer 5

find the radius also

Answer 6

oops -- (-6,-1)

Answer 7

Is the radius 3? or is it 9?

Answer 8

Nevermind, ignore that above

Answer 9

none, try again

Answer 10

'sorry again. r=4

Answer 11

yeah :)

Answer 12

Yeah it is 4 :)
