Identify the conic as a circle or an ellipse. Then find the center, radius, vertices, foci, and eccentricity of the conic (if applicable), and sketch its graph. \(9 x^{2}+25 y^{2}-36 x-50 y+60=0\)
Find the standard form of the equation of the ellipse with the given characteristics and center at the origin. Vertices: (0,±5) ; passes through the point (4,2)
Show that \(a^{2}=b^{2}+c^{2}\) for the ellipse \(\frac{x^{2}}{a^{2}}+\frac{y^{2}}{b^{2}}=1\) where \(a>0, b>0,\) and the distance from the center of the ellipse (0,0) to a focus is \(c\).
Determine whether the statement is true or false. Justify your answer. It is possible for a parabola to intersect its directrix.
Find the standard form of the equation of the ellipse with the given characteristics and center at the origin. Vertices: (0,±8)\(;\) foci: (0,±4)
