Answer 2

Answer:

Final answer:

The given equation represents a circle. The square root of 81 (which is 9) is the radius of this circle and hence denotes the range of the cellular phone tower. So, the range of the cell phone tower is 9 units.

Explanation:

The given equation models a circle where (x-5)² and (y-7)² are the squared coordinates of the circle, and 81 is the square of the radius of the circle. The radius represents the range of the cellular tower in this case. The radius (or range, in this context) is the square root of 81 which is 9 units. Therefore, the range of the cell phone tower is 9 units.
