Answer:
(x - 5)² + (y - 2)² = 9
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r the radius
Here (h, k ) = (5, 2 ) and r = 3 , then
(x - 5)² + (y - 2)² = 3² , that is
(x - 5)² + (y - 2)² = 9
Answer:
Base Fee = $7
