Pre-Calculus Q1

Question 1

is a curve obtained by intersecting a cone (right
circular cone; its nappe), specifically double cones, with a
plane.

Answer 1

CONIC

Question 2

horizontal parallel form the base

Answer 2

CIRCLE

Question 3

tilted plane intersects only one to form a bounded curve

Answer 3

ELLIPSE

Question 4

-unbounded, slanting height

Answer 4

Parabola

Question 5

-intersects both cones to form unbounded curves

Answer 5

hyperbola

Question 6

A _____ consists of all points on the plane equidistant from a fixed
point called the center. The distance from the center to any point on the _____
is constant and is called the radius of the ______.

Answer 6

CIRCLE

Question 7

(x−h)^2+(y−k)^2=r

Answer 7

CIRCLE (h, k)

Question 8

x^2+y^2=r^2

Answer 8

CIRCLE (0, 0)

Question 9

Radius: h^2+k^2-E

Answer 9

Circle

Question 10

The locus/set of points, where the distance from the focus is equal to the distance from the directrix. Halfway between is the vertex. Eccentricity is one.

Answer 10

PARABOLA
