A right circular cone is intersected by a plane that runs parallel to the base of the cone, as in the picture below. What object is produced from this intersection?

The  object that is produced from this intersection is:

Parabola.

Step-by-step explanation:

The intersection of this given plane and a cone will form a parabola.

( Since a circle is formed when the plane is parallel to the base of a cone.

Hyperbola is formed when a plane cuts both the napes of a cone by some angle.

and a ellipse is formed when the plane cuts both the slant height of one nape of a cone )

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
