The undefined terms which are used to define a ray is:

Point and a line.

Step-by-step explanation:

The undefined terms in coordinate geometry are:

Line, Points and Plane.

since a line do not have any length, Point has a location but no size.

A line has no width and it extends infinitely and is one dimensional.

and a plane extends infinitely in both the dimensions.

<em>Ray:</em>

<em>A ray is part of a line, has one fixed endpoint, and extends infinitely along the line from the endpoint.</em>

Hence, the undefined terms which are used to define a ray is:

Point and a line.

Write the standard equation for the hyperbola with the following conditions: vertices: (-2, -3) and (6, -3) foci: (-4, -3) and (
STALIN [3.7K]
Hello,

Vertices are on a line parallele at ox (y=-3)

The hyperbola is horizontal.

Equation is (x-h)²/a²- (y-k)²/b²=1

Center =middle of the vertices=((-2+6)/2,-3)=(2,-3)
(h+a,k) = (6,-3)
(h-a,k)=(-2,-3)
==>k=-3 and  2h=4 ==>h=2
==>a=6-h=6-2=4 (semi-transverse axis)

Foci: (h+c,k) ,(h-c,k)
h=2 ==>c=8-2=6

c²=a²+b²==>b²=36-4²=20

Equation is:
\boxed{ \dfrac{(x-2)^2}{16} - \dfrac{(y+3)^2}{20} =1}&#10;&#10;
