Multiple Choice

Graph the Polar Equations of Conics
- $r = \frac { 15 } { 5 + 10 \sin \theta } \quad$ Identify the directrix and vertices.

• A) directrix: \(\frac { 3 } { 2 }\) unit(s) abovethe pole at \(y = \frac { 3 } { 2 }\) vertices: \(\left( 1 , \frac { \pi } { 2 } \right) , \left( 3 , \frac { 3 \pi } { 2 } \right)\)
• B) directrix: \(\frac { 3 } { 2 }\) unit(s) below the pole at \(y = - \frac { 3 } { 2 }\) vertices: \(\left( 1 , \frac { \pi } { 2 } \right) , \left( 3 , \frac { 3 \pi } { 2 } \right)\)
• C) directrix: \(\frac { 3 } { 2 }\) unit(s) to the left ofthe pole at \(x = - \frac { 3 } { 2 }\) vertices: \(( 1,0 ) , ( 3 , \pi )\)
• D) directrix: \(\frac { 3 } { 2 }\) unit(s) to the right of the pole at \(x = \frac { 3 } { 2 }\) vertices: \(( 1,0 ) , ( 3 , \pi )\)
