Answer:
r = 6.4/(1+sin(θ))
Step-by-step explanation:
As the attachment shows, for the given directrix and eccentricity, the equation is ...

To solve, lets convert the number so that they both have the similar exponents.

in comparing 20,000*10^-28 and 9*10^-28, we can see that one is nearly 2,000 times bigger than the other
20,000/9=2222
Answer= C
