Two cones are cut by a plane as shown, where the plane is perpendicular to the bases. the cross-section of the cones and the plane is a) a circle. b) an ellipse. c) a parabola. d) a hyperbola.

can i just ask is there a diagram for this question

Hyperbola

Step-by-step explanation:

A conic section is a figure formed by the intersection of a plane and a circular cone. Depending on the angle of the plane with respect to the cone, a conic section may be a circle, an ellipse, a parabola, or a hyperbola.

When the cutting plane is perpendicular to the bases, then two cones connected by vertex will give a hyperbola

THus a hyperbola is formed when two cones are cut by a plane perpendicular to the bases of the cones.

Answer is hyperbola

The line joining the foci is called the principal axis and the points of intersection of the conic with the principal axis are called the vertices of the conic. The line segment joining the vertices of a conic is called transverse axis in the hyperbola

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
