1.
A Cellular phone networks use towers to transmit calls to a circular area. On a grid of a
province, the coordinates that correspond to the location of the towers and the radius each
covers are as follows: Wise Tower is at (-5,-3 ) and covers a 9 km radius; Global Tower is at (3,6)
and covers 4km radius; and Star Tower is at (12, -3) and covers a 6 km radius.
a. What equation represents the transmission boundaries of Wise tower?
b. Which tower transmits calls to phones located at (12,2)?
2. A radio signal can transmit messages up to a distance of 3 km. If the radio signal's origin is located
at a point whose coordinates are ( 4,9), what is the equation of the circle that defines the boundary up
to which the messages can be transmitted?
