Which conic section is formed when a plane intersects the central axis of a double-napped cone at the same angle as the generator?

circle

ellipse

hyperbola

parabola

ans is parabola

parabola            

Step-by-step explanation:

Parabola: In mathematics, the term "parabola" is described as a specific plane curve that is considered as "mirror-symmetrical" and is approximately considered as being in a U-shaped. However, it tends to fit other mathematically different descriptions superficially that can all be said to proved to describe the similar curves. However, one single description associated with a parabola is being involved in a line or a point.

In the question above, the given statement represents parabola.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
