Does a conic section have vertices?
No, a conic section does not have vertices. If it is a circle, it has a center; if it is a parabola or hyperbola, it has a focus; and if it is an ellipse, it has foci.
What is the name of the point that you use to define a parabola?
it's called the focus

Focus
In the ellipse shown below each point marked with a dot is called a(n) .?

Are the directrix and focus different distances from a given point on a parabola?
One definition of a parabola is the set of points that are equidistant from a given line called the directrix and a given point called the focus. So, no. The distances are not different, they are the same. The distance between the directrix and a given point on the parabola will always be the same as the distance between that same point on the parabola and the focus. Any point where those two distances are equal would be on the parabola somewhere and all the points where those two distances are different would not be on the parabola. Note that the distance from a point to the directrix is definied as the perpendicular distance (also known as the minimum distance).
The center of a circumscribed circle is called what?
the center of a circumscribed circle is called the focus.
What does the center of each circle represent in the epicenter of an earthquake?
it is the seismic focus center
What are synonyms for center?
middle, heart, focus, core, nucleus, hub, pivot, kernel, focus
What does the center of each earthquake circle represent?
It represent the seismic wave focus centerThe center of each circle is a seismograph's location.
Geologists use circles to find the epicenter of an earthquake what does the center of each circle re?
Focus Center
What is the middle part of a circle called?
the focus, or centre. focus is more widely used
What is the distance between the focus of a circle and the outside?
We're not sure what the 'focus' of a circle is, but since there's only one significant pointinside a circle, we'll assume the question is referring to the 'center', and we'll assumethe 'outside' means the circular line (which is actually the circle).(Isn't it great that before we can do an answer around here, we have to re-write thequestion so that it makes sense ! ?)The distance between the center of a circle and the circular line is the circle's "radius".
Does a conic section have vertices?
No, a conic section does not have vertices. If it is a circle, it has a center; if it is a parabola or hyperbola, it has a focus; and if it is an ellipse, it has foci.
What is the center of an earthquake?
It is called the focus, and the point on Earth's surface located directly above the earthquake focus is called the epicenter of the earthquake.
Underground center of an earthquake?
Earthquakes occur underground and are felt on the surface. The center of an earthquake on the surface is called the epicenter, and the center of the earthquake underground, where it occurs, is called the hypocenter or focus.
What is also known as the 'focus' - the place underground where an earthquake originates?
The Underground center of an earthquake is called the focus.
What are some other words for the word hub?
pivot, axis, fulcrum, center, middle, core, heart, focus, nucleus, kernel, polestar
