What is the center of a circle represented by the equation (x+9)^2+(y-6)^2=10

(- 9, 6)

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 is the radius

(x + 9)² + (y - 6)² = 10 ← is in standard form

with (h, k) = (- 9, 6) ← coordinates of centre

Since we have

where P is the pression, F is the force and S is the surface, we can solve the formula for the force as follows

In order to have consistent units of measure, we convert

and we plug the values:
