The path of a softball is modeled by \(-12.5(y-7.125)=(x-6.25)^{2},\) where the coordinates \(x\) and \(y\) are measured in feet, with \(x=0\) corresponding to the position from which the ball was thrown. (a) Use a graphing utility to graph the trajectory of the softball. (b) Use the trace feature of the graphing utility to approximate the highest point and the range of the trajectory.
Find the standard form of the equation of the ellipse with the given characteristics. Vertices: (0,2),(4,2)\(;\) endpoints of the minor axis: (2,3),(2,1)
Find the standard form of the equation of the ellipse with the given characteristics and center at the origin. Vertices: (0,卤8)\(;\) foci: (0,卤4)
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. \(\frac{x^{2}}{25}+\frac{y^{2}}{16}=1\)
Find the vertex, focus, and directrix of the parabola. Use a graphing utility to graph the parabola. \(x^{2}-2 x+8 y+9=0\)
