Which best describes a parabola?
Given a straight line (a directrix) and a point (the focus) which is not on that line, a parabola is locus of all points whose distance form the directrix is the same as its distance from the focus.
What is the locus of points that are 10 centimeters from a given point?
The locus of points (or collection of all points) that are 10 centimeters from a given point would be a circle (of radius 10 cm) in two dimensions, and a sphere (of radius 10 cm) in three dimensions.
Although the locus of points idea can be used to define a straight line and circle more complex shapes such as parabolas must be defined a different way. True or False?
Certainly false for parabolae; a parabola is the locus of points in a plane which are equidistant from a point (the focus) and a line (the directrix) in that plane. It's also false for an ellipse, which is the locus of points in a plane where the sum of the distances from two other points in that plane (the foci) is constant. AND false for a hyperbola, which is the locus of points in a plane where the absolute value of the DIFFERENCE in the distance from two points in that plane (also the foci) is constant. Alternatively, a hyperbola is the locus of points in a plane where the ratio of the distance to one of the foci and to a line (the directrix) is constant (which is larger than 1; if it's exactly equal to 1, you get a parabola instead).All of these are only slightly more complicated than circles, and in fact they, alone with circles, are called "conic sections" because they all are formed by the intersection of a plane with a right circular conical surface.
What best describes a single fixed point that is the same distance from the parabola as the directrix is from the parabola?
Locus
What is a radius of 1 cm?
It is the set of all points that are at a distance of 1 cm from a fixed point (called the centre).
What is the locus of points at a given distance from a given point?
A circle
What is a locus of points equidistant from a point?
A locus of points is just the set of points satisfying a given condition. The locus of points equidistant from a point is a circle, since a circle is just a set of points which are all the same distance away from the center
What is the locus of all points that are a fixed distance from a given point?
triangle
A compass draws all points a given distance from a fixed point thereby creating a locus of points for a circle?
True
A compass draws all points at a uniform distance from a fixed point thereby creating a locus of points for a circle?
true
Is locus is center of circle or any point on circumference of circle?
The center isn't the locus, and a point on the circumference isn't the locus.The whole circumference of the circle is the locus.It's the locus of all points that have the same distance from the center of the circle.
The center of a circle is a example of what?
A point. In fact it is fixed point and the locus of all points, in a plane that is a fixed distance from that fixed point defines the circle.
Is line is a locus of point?
No. A line is the locus of all points located between any two points.
Locus of points equidistant from a point?
circle
What does parabola mean in mathematical terms?
It is the locus of all points such that their distance from a fixed line (the directrix) is the same as their distance from a fixed point which is not on that line (the focus).
The locus of all points in space equidistant from a given point?
That's a sphere whose radius is the constant equal distance.
What is the denifion of a circle?
I assume that you are asking about the definition of a circle. A circle is a locus of points in a plane that are at a constant distance from a fixed point.
