Which conic section results from the

intersection of the plane and the double-napped

cone where the plane is parallel to the

generating line?

parabola

hyperbola

circle

ellipse

A parabola.

Step-by-step explanation:

A circle is generated when the plane is perpendicular to the symmetry axis of the double-napped cone.

An hyperbola is generated when the plane is parallel with the symmetry axis of the double-napped cone.

An ellipse is generated when the plane is not perpendicular to nor parallel with the symmetry axis of the double-napped cone.

Hence, the right answer is a parabola.

1 1/4 hours

step-by-step explanation:

2/4 + 2/4 + 1/4 = 5/4 or 1 1/4

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
