# A cell tower

A cell tower is located at coordinates (-5, -7) and has a circular range of 12 units. If Mr. XYZ is located at coordinates (4,5), will he be able to get a signal?

Result

x =  0

#### Solution:

$d_{1}=12 \ \\ d_{2}=\sqrt{ (-4-4)^2+(-7-5)^2 }=4 \ \sqrt{ 13 } \doteq 14.4222 \ \\ \ \\ d_{2}>d_{1} \ \\ \ \\ x=0$ Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
