Question

A plane intersects a double-napped cone so that it contains the generating line.

Which geometric shape is formed?
Circle
Point
Parabola
line
And
17. what is the length of the segment whose endpoints are A(-4,3) and B(10,6) in square root form.

Answer 1

To understand this picture 2 cones that are stacked one on top of another. A double-napped cone is created when a generator is rotated about a fixed vertical axis. A line is created when the cone is cut by a plane containing the generator. Please see the attachment to help you understand this.

I hope this helps, Regards.
