### When the first number in an ordered pair is 0 where is the point located?

The first number in an ordered pair (of rectangular coordinates)
is the distance from the origin along the x- axis.
If the number is 0, then any point having this coordinate must
lie on the y-axis.
If the second number is 0 then the point is at the origin
(0,0).
If the second number is positive then the point lies on the
y-axis above the origin.
If the second number is negative then the point lies on the
y-axis below the origin.

### What are the differences between four conic sections?

A conic section is the intersection of a plane and a cone.
The circle is a conic section where the plane is perpendicular
to the axis of the cone. The special case of a point is where
the vertex of the cone lies on the plane.
The ellipse is a conic section where the plane is not
perpendicular to the axis, but its angle is less than one of the
nappes. The special case of a point is where the vertex of the
cone lies on the plane.
The parabola is a conic section where the plane is parallel to
one of the nappes. The special case of two intersecting lines is
where the vertex of the cone lies on the plane.
The hyperbole is a conic section where the angle of the plane is
greater than on of the nappes. There are two sides to the
hyperbole. The special case of two lines intersecting is where
the vertex of the cone lies on the plane.

### State ane prove perpendicular axis theorem?

In physics, the perpendicular axis theorem (or plane
figure theorem) can be used to determine the moment of inertia
of a rigid object that lies entirely within a plane, about an axis
perpendicular to the plane, given the moments of inertia of the
object about two perpendicular axes lying within the plane. The
axes must all pass through a single point in the plane.
Define perpendicular axes , , and (which meet at origin ) so
that the body lies in the plane, and the axis is perpendicular to
the plane of the body. Let Ix, Iy and
Iz be moments of inertia about axis x, y, z
respectively, the perpendicular axis theorem states that[1]
This rule can be applied with the parallel axis theorem and the
stretch rule to find moments of inertia for a variety of
shapes.
If a planar object (or prism, by the stretch rule) has
rotational symmetry such that and are equal, then the perpendicular
axes theorem provides the useful relationship:
Derivation
Working in Cartesian co-ordinates, the moment of inertia of the
planar body about the axis is given by[2]:
On the plane, , so these two terms are the moments of inertia
about the and axes respectively, giving the perpendicular axis
theorem.

### How do you make a circle graph?

There are two common ways to graph circles: using a cartesian
graph and using a polar graph.
For a cartesian graph, there are two familiar axes x and y which
are orthogonal to each other. The formula for a circle is "x^2 +
y^2 = a constant".
In a polar graph, there are no axes and all points are defined
by their radius from the center point, and the angle of the
direction the point lies from the center.
In a polar coordinate system, a circle is simply "r = a
constant".
