Answer:
B. 4 ÷ 5
Step-by-step explanation:
4/5 means you are dividing 4 by 5. So the answer would be B.
Because the coefficient is zero, there will be no correlation
The circle has shorter perimeter
Draw arcs on either side of a given point on the line
Step-by-step explanation:
Given that,
Directrix, d= -5, and eccentricity, e = 2.
The polar equation of the conic is given by :
![r=\dfrac{ed}{1-e\cos\theta}](https://tex.z-dn.net/?f=r%3D%5Cdfrac%7Bed%7D%7B1-e%5Ccos%5Ctheta%7D)
Put all the values,
![r=\dfrac{-5\times 2}{1-2\cos\theta}\\\\=\dfrac{-10}{1-2\cos\theta}](https://tex.z-dn.net/?f=r%3D%5Cdfrac%7B-5%5Ctimes%202%7D%7B1-2%5Ccos%5Ctheta%7D%5C%5C%5C%5C%3D%5Cdfrac%7B-10%7D%7B1-2%5Ccos%5Ctheta%7D)
As e>1, it is a hyperbola. Hence, this is the required solution.
