On a grid map of a province, the coordinates that correspond to the location of cellular phone tower is (-7, 4) and it can transmit signals up to a 12 km radius. What is the equation that represents the transmission boundaries of the tower? Is the household located at (5, -8) within the transmission boundaries?
\n" ); document.write( "----------------
\n" ); document.write( "Assuming (-7,4) is in km.
\n" ); document.write( "----
\n" ); document.write( "The coverage circle is
\n" ); document.write( "\"%28x%2B7%29%5E2+%2B+%28y-4%29%5E2+=+12%5E2\"
\n" ); document.write( "=================
\n" ); document.write( "Find the distance from (-7,4) to (5,-8)
\n" ); document.write( "If it's <= 12 kms it's within the boundaries.\r
