question 22

Multiple Choice

- $$r = \frac { 21 } { 5 - 2 \cos \theta }$$

• A) \(\mathrm { e } = \frac { 2 } { 5 } , \mathrm { a } = 5 , \mathrm {~b} = \sqrt { 21 } , \mathrm { c } = 2\)
• B) \(\mathrm { e } = \frac { 2 } { 5 } , \mathrm { a } = 21 , \mathrm {~b} = 4 , \mathrm { c } = 5\)
• C) \(\mathrm { e } = \frac { 5 } { 2 } , \mathrm { a } = 2 , \mathrm {~b} = \sqrt { 21 } , \mathrm { c } = 5\)
• D) \(e = \frac { 5 } { 2 } , a = 21 , b = 4 , c = 5\)
