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

1.
Slope-300.
Y int: 40,000
Y=300x+40000
2.
S: -5
Y: 250
Y=-5x+250
3.
S: 2
Y: 5
Y=2x+5
4.
S: 150
Y: 350
Y=150x+350
The last question is cut off.
Answer:
None of these
Step-by-step explanation:
The lines aren't parallels so none of these property's can be applied
Domain is all Real Numbers and Range is from 0, but not including 0, to infinity. So it would be the first one
