Answer:
1)A parabola is defined as a set of points in a plane which are equidistant from a straight line or directrix and focus.
The hyperbola can be defined as the difference of distances between a set of points, which are present in a plane to two fixed points is a positive constant.
2)A parabola has single focus and directrix
A hyperbola has two foci and two directrices
3)Eccentricity, e = 1(parabola)
Eccentricity, e>1(hyperbola)
4)The two arms present in a parabola should be parallel to each other
The arms present in hyperbola are not parallel to each other
5)It has no asymptotes(parabola)
It has two asymptotes(hyperbola)

The first ordered pair is ( -4 , -3 )
The second ordered pair is ( 8, 3 )
=================================================
Explanation:
The first point is (x,-3) where x is unknown. It pairs up with y = -3 so we can use algebra to find x
x-2y = 2
x-2(-3) = 2 ... replace every y with -3; isolate x
x+6 = 2
x = 2-6
x = -4
The first point is (-4, -3)
---------------------------
We'll do something similar for the other point. This time we know x but don't know y. Plug x = 8 into the equation and solve for y
x-2y = 2
8-2y = 2
-2y = 2-8
-2y = -6
y = -6/(-2)
y = 3
The second point is (8, 3)
The eee part is the right part because I’m not trying to get points I’m so sorry
Answer:
The height of the roof in his house is 72.43 ft.
Step-by-step explanation:
The volume of square pyramid is :
B= area of the base.
h= the height.
Given that,
The roof is a square pyramid in shape. The volume of the roof is 18929.333 cubic feet.
The side length of the base of the roof is 28 feet.
Since the base of the roof is square in shape.
The area of the square is = side²
The area of the base is =(28×28) square feet
=784 square feet
Assume the height of the roof be h ft.
Then, the volume of the roof is = 
square feet.
According to the problem,
ft.
The height of the roof in his roof is 72.43 ft.
