The correct answer is b), or x² = -12y.
Explanation:
This equation may be written in standard form as
The coefficient in front of x² is negative so the curve is downward.
The vertex has coordinates (0,0).
The vertex is equidistant from the directrix and the focus, so the focus is (0, -3).

Therefore, let the length of the hypotenuse be 'x.'
625+3600=
4225=
Therefore,
65=x
The length of the hypotenuse is B.65 centimetres.
