Eight.
There are infinitely many points. One of these is (10, 0).
There are infinitely many such points. One of them is: (2,236, 4.291)
The points are (-0.25, 0) and (0, 1)
5
An infinite number of points lie on that line. One such would be (40, 65).
An arc (circumference only), or a segment.
Since there are no "following" points, none of them.
(4,5) and (2,0)
There are infinitely many points. One of these is (10, 0).
There are infinitely many such points. One of them is: (2,236, 4.291)
The points are (-0.25, 0) and (0, 1)
A "great circle" is any circle on a sphere whose center is also the center of the sphere. The shortest distance between two points on the surface of a sphere is a piece of the great circle on which both points lie. A "small circle" is any circle on the sphere that's not a 'great' circle.
There are infinitely many points. One of these is (-7, 1)
This is not possible, since the point (4,6) lies inside the circle : X2 + Y2 = 16 Tangents to a circle or ellipse never pass through the circle
Every diameter of the circle.
the artic circle
There are infinitely many points on the line. One such is (-6, 3.33...)
