Which intersection forms a parabola?

a) a plane intersects only one nappe of a double-napped cone, and the plane is parallel to the generating line of the cone.

b) a plane intersects only one nappe of a double-napped cone, and the plane is not parallel to the generating line of the cone.

c) a plane intersects both nappes of a double-napped cone, and the plane does not intersect the vertex.

d) a plane intersects only one nappe of a double-napped cone, and the plane is perpendicular to the axis of the cone.

A) A plane intersects only one nappe of a double-napped cone, and the plane is parallel to the generating line of the cone.

Step-by-step explanation:

A) Parabola

A plane intersects only one nappe of a double-napped cone, and the plane is parallel to the generating line of the cone.

The plane has to intersect with the base of the cone and forms a parabola.

B) Form Circle and hyperbola

C) Forms hyperbola  

D) Forms circle

Hope this will helpful.

Thank you.

your answer is -9

step-by-step explanation:

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x
