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;
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

Step-by-step explanation:

<u>If ABC i.e angle of centra = 124°Then, we know that angle at any where of Circle is 1/2 if central angle </u>
- <u>If ABC i.e angle of centra = 124°Then, we know that angle at any where of Circle is 1/2 if central angle So, ADC = 124/2 => ⛰ ADC = 62°</u><u>.</u>

Answer: x = square root of -x + 3 / 2
Step-by-step explanation:
2x^2 + x - 1 = 2
add 1 to both sides
2x^2 + x = 3
subtract x from both sides
2x^2 = -x + 3
square root both sides
2x = square root of -x + 3
divide by 2
x = square root of -x + 3 / 2
