Answer:
mean is the best way
Step-by-step explanation:
Answer:
The answer is (d) ⇒ eccentricity = 6 , hyperbola , directrix x = 3/2
Step-by-step explanation:
∵ r = ek/(1 ± ecosФ)
∵ r = 9/(1 + 6cosФ)
∴ e = 6 ⇒ eccentricity = 6
∵ e > 1
∴ The conic is hyperbola
∵ ek = 9
∴ k = 9/6 = 3/2
∴ The directrix x = 3/2
Answer:
1 1/3
Step-by-step explanation:
1/3 divided by 1/4
keep change flip so 1/3 times 4/1 multiply straight across
