 Question 196700: Identify the conic section represented by each equation. For a parabola give the vertex. For a circle give the center and radius. For an ellipse or a hyperbola give the center and foci. (1) x^2+y^2-4x+2y+1=0 I found that the equation would be (x-2)^2 + (y+1)^2=4 This would be a circle The center would be (2, -1) The raidus would be 2 (2)x^2-4x-y+7=0 I found that the equation would be y=(x-2)^2 + 7 This is a parabola The vertex is at (7,2) Is this correct? I'm not quite sure if I am doing these right... Thank you! Click here to see answer by stanbon(57361)

 Question 196696: Identify the conic section represented by each equation. For a poraola, give the vertex. For a circle, give the center and radius. For an ellipse or hyperbola, give the center and foci. (1) x^2-4y^2+4x+8y-16=0 For this one I found that the equation would be (x+2)^2/16-(y-1)^2/4=1 I got that this is a hyperbola. I found the center to be (-2,1) I found the foci to be (4.47,0) (-4.47,0). (2) 25x^2+4y^2-50x-24y-39=0 For this one I found that the equation would be (x-1)^2/4 + (y-3)^2/25=1 I got that this is an ellipse I found that the center is (1,3) I found that the foci is (0,4.58) (0,-4.58) Is this correct? I'm not really sure what I'm doing.... Thank you!! Click here to see answer by Alan3354(30993)

 Question 197706: My problem is I have the equation: x^2 - y^2 + 24y > (or equal to) 148 Well I put it in graphing form which I believe is (x^2)/292 - (y^2+12)/292=1 Which makes it a Hyperbola, and I need to graph it but the radius is the square root of 292, which is 17.08800749, and that is too big to be graphed on my paper and that can't happen because it has to fit. So what did I do wrong? Could you tell me the correct equation and the vertical and horizontal radius? I did not receive this question from a textbook.
