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. . \(x^{2}+y^{2}-4 x+6 y-3=0\)
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. \(\frac{(x+3)^{2}}{12}+\frac{(y-2)^{2}}{16}=1\)
Determine whether the statement is true or false. Justify your answer. If the vertex and focus of a parabola are on a horizontal line, then the directrix of the parabola is vertical.
Each cable of the Golden Gate Bridge is suspended (in the shape of a parabola) between two towers that are 1280 meters apart. The top of each tower is 152 meters above the roadway. The cables touch the roadway midway between the towers. (a) Draw a sketch of the bridge. Locate the origin of a rectangular coordinate system at the center of the roadway. Label the coordinates of the known points. (b) Write an equation that models the cables. (c) Complete the table by finding the height \(y\) of the suspension cables over the roadway at a distance of \(x\) meters from the center of the bridge. $$\begin{array}{|c|c|}\hline \text { Distance, } \boldsymbol{x} & \text { Height, } \boldsymbol{y} \\\\\hline 0 & \\\100 & \\\250 & \\\400 & \\\500 & \\\\\hline\end{array}$$
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. \(6 x^{2}+2 y^{2}+18 x-10 y+2=0\)
