Question

What is the equation that represent the transmission boundary of the tower if the cellcular phone is (-3,1) and transmit signal 4km radius.

Answer 1

Answer: if correct mark me brainliest

Step-by-step explanation:

Given : Tower 1 is at (-5, -3) and covers a 9 km radius; Tower 2 is at (3,6) and covers a 4 km radius; and Tower 3 is at (12, -3) and covers a 6 km radius.

To Find : What equation represents the transmission boundaries of each tower?

Which tower transmits calls to phones located at (12,2)?(-6,-7)?(2,8)?(1,3)?

c. If you were a cellular phone user, which cellular phone network will you subscribe to? Why?​

Solution:

Tower 1 is at (-5, -3)  

and covers a 9 km radius

Equation is  ( x -(-5))² + (y -(-3))² = 9²

=> (x + 5)² + (y + 3)² = 81

Tower 2 is at (3,6) and covers a 4 km radius

(x - 3)² + (y - 6)² = 16

Tower 3 is at (12, -3) and covers a 6 km radius.

(x - 12)² + (y + 3)² = 36

(12,2)  - TOWER 3

(-6 , -7) , TOWER 1

(2 , 8) , TOWER 2

(1 , 3) -  TOWER 1  and TOWER 2

I will subscribe Tower 1  network as that has maximum area coverage
