Answer:
Choice D is correct
Step-by-step explanation:
The eccentricity of the conic section is 1, implying we are looking at a parabola. Parabolas are the only conic sections with an eccentricity of 1.
Next, the directrix of this parabola is located at x = 4. This implies that the parabola opens towards the left and thus the denominator of its polar equation contains a positive cosine function.
Finally, the value of k in the numerator is simply the product of the eccentricity and the absolute value of the directrix;
k = 1*4 = 4
This polar equation is given by alternative D

B
Step-by-step explanation:
The common factor of 7 and 15 is 1
Question:
Trent had $20.
He now has $7.50 left.
Let N = price per notebook.
N = (20.00 - 7.50)/5
N = $2.50
Each notebook sells for $2.50.
