Best ResponseYou've already chosen the best response.0This is calculus. You need to use implicit differentiation and they plug in (2,5). At least that is what I recall from calculus.

Best ResponseYou've already chosen the best response.1The center of the circle is (0,0). The slope from (0,0) to (2,5) is 5/2 So the slope of the tangent is 2/5. Now write the equation of a line that contains the point (2,5) and has slope 2/5. That is the equation of the tangent.

Best ResponseYou've already chosen the best response.0Because that is a calculus question. I would ask that question if I was teaching calculus. It could be a geometry question, but not sure I would ask that question if I was teaching geometry.
