Cell towers are used to transmit calls. Each tower transmits to a circular region. On a grid of a city, the coordinates of three towers and the radius of its transmission are provided. Tower A is at (0, 0) and has a radius of 3 miles.
Tower B is at (5, 3) and has a radius of 2.5 miles.
Tower C is at (2, 5) and has a radius of 2 miles. 16)
Write the equation of the transmission boundary for all three towers. (eq of the 3 circles)
