Question

Telecommunication towers can be used to transmit cellular phone calls. A graph with units measured in kilometers shows tower A at point (0, 0), Tower B at (0, 5) and Tower C at (6, 3). These towers have a range of 3 km.a. Graph towers with paper/pencil.b. Are there any locations that mayreceive calls from more than one tower? Explain.

Answer 1

Part a

Remember that

The equation of a circle in center radius form is equal to

`(x-h)^2+(y-k)^2=r^2`

Let

A, B , and C the three towers

A(0,0)

B(0,5)

C(6,3)

For each tower, we have to draw a circle with ra adius r= 3km

the equations of each circle is

A ----> x^2+y^2=9

B ---> x^2+(y-5)^2=9

C ---> (x-6)^2+(y-3)^2=9

using a graphing tool

see the figure below

please give me a minute to draw the figure
