Aparabola, with its vertex at the origin, has a directrix at y = 3. which statements about the parabola are true? check all that apply.
the focus is located at (0,–3).
the parabola opens to the left.
the p value can be determined by computing 4(3).
the parabola can be represented by the equation x2 = –12y.
the parabola can be represented by the equation y2 = 12x.

Answer :- 1.The focus is located at (0,–3).

4.The parabola can be represented by the equation x2 = –12y.

Explanation:-

Given:- A parabola, with its vertex at the origin, has a directrix at y = 3.

⇒ the parabola is symmetric to the y -axis and opens to the downwards as it opens opposite to the directrix.

and focus is located at (0,-3) as for directrix y=a focus =(0,-a)

⇒The parabola can be represented by the equation with a=3

p=distance between the vertex and focus=|-3-0|=3 units

Thus options 1, 4 are correct.

the answer is thin because within context, the stanza concludes the and frail tone the people have toward each other, and the fact that it would be thin, makes the most sense compared to "pliable" or "not hard or firm to the touch". hope this , good luck.
