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: $( 1,0 ) , ( 3 , \pi )$
