Determine the graph of the polar equation r =6/2-2cos theta<br> (picture provided)
vredina [299]

Answer:

Choice D is correct

Step-by-step explanation:

The first step is to write the polar equation of the conic section in standard form by dividing both the numerator and the denominator by 2;

r=\frac{3}{1-cos(theta)}

The eccentricity of this conic section is thus 1, the coefficient of cos θ. Thus, this conic section is a parabola since its eccentricity is 1.

The value of the directrix is determined as;

d = k/e = 3/1 = 3

The denominator of the polar equation of this conic section contains (-cos θ) which implies that this parabola opens towards the right and thus the equation of its directrix is;

x = -3

Thus, the polar equation represents a parabola that opens towards the right with a directrix located at  x = -3. Choice D fits this criteria

This is completely wrong for logical and mathematical reasons, but for the sake of time I will go over the mathematical reason.

Because all percentages are out of 100, nothing can physically be over 100%, though it is used frequently in hyperbolic sentences and exaggerated statements.

Hope I helped and good luck!

Elden [556K]
There are 900 people that subscribe to the Sunday edition, and 150 that subscribe only to the Sunday edition.

There are 1350 that subscribe to the daily morning edition either alone or with the Sunday edition; this leaves

1500-1350 = 150 that only subscribe to the Sunday edition.
