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
In the ellipse shown below each point marked with a dot is called a?
Focus
In the ellipse shown below each point marked with a dot is called a(n) .?
Focus
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
Where is the nucleus in a sentence?
The nucleus in a sentence is typically the main idea or the subject that the rest of the sentence revolves around. It is usually the most important element in the sentence and provides the primary focus or message.
What is the middle part of a circle called?
the focus, or centre. focus is more widely used
What is the center of an earthquake?
The center of an earthquake is called the focus or hypocenter. It is the point within the Earth's crust where the earthquake originates. The point on the Earth's surface directly above the focus is called the epicenter.
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 does the center of each circle represent in a epicenter?
The center of a circle in an epicenter represents the point on the Earth's surface directly above the focus or hypocenter of an earthquake. This is where the seismic waves originate.
What do you call the center of a seismic wave?
The center of a seismic wave is called the focus or hypocenter. This is the point within the Earth where the seismic waves originate.
