網頁2024年10月8日 · Let me try to answer. You are given that the standard equation of a circle ---> (x−h)^2+ (y−k)^2=r^2 where, r=radius of the circle. With these relations in mind, lets go back to x^2 + y^2 - 8x + 2y = -1 with a focus on converting x^2 + y^2 - 8x + 2y to 2 complete squares (1 with x and 1 with y).

But, the tangent at (x 1 , y 1 ) is given by Note: When a line touches a circle, then the point of contact is the foot of the perpendicular drawn from the centre of the circle onto the line. 網頁The given equation can be written as (x−4)2+(y+2)2 =42. We know that the standard equation of the circle with centre (h, k) is (x−h)2+(y−k)2 =r2. Comparing the given equation with the standard equation, we get centre ≡ (4, -2), and radius = 4. Since co-ordinates of the centre of the circle are (4, -2), therefore the given circle touches ... how to make papyrus avatar in roblox
