A cellular phone network uses towers to transit calls. Each tower transmits a circular area. on a grid of a city, the equations given represent the transmission boundaries of the towers. Tell which towers, is any, transmit to a phone located at M(3.5, 4.5). Tower A: x^2 + y^2 = 9

Tower B: (x - 5)^2 + (y - 3)^2 = 6.25

Tower C: (x - 2)^2 + (y - 5)^2 = 4

Towers B and C transmit to the phone.

Step-by-step explanation:

First, let see the location of the center for each tower:

Tower A

Tower B

Tower C

Now, the distance between the location of the phone and any of the towers by means of the Pythagorean equation. The phone is under the influence of a tower only if distance is less than transmission boundaries. Then:

Tower A

Tower B

Tower C

Towers B and C transmit to the phone.
