When The circle below is centered at the point (-1 -3) and has a radius of length 5. What is its equation?
Equation of the circle: (x+1)^2 +(y+3)^2 = 25
What numbers have the absolute value of 1?
All complex number that can be represented by the coordinates of points on the unit circle, that is, the circle with its centre at the origin and a radius of 1 unit.
Which point does not lie on the circle centered at A3 1 and passing through the origin 0 0?
Believe it or not, there are lots of such points.
What is the equation of a circle centered at the origin with a radius of 1?
x² + y² = 1.
Prove or disprove that the point (2 1) lies on the circle centered at the origin with a radius of 2.?
It is not true because the distance from (0, 0) to (2, 1) works out as the square root of 5 which is the circle's radius.
What is unit circle?
The unit circle is a circle with its center at the origin and a radius of ' 1 '.
The circle below is centered at the point (1, 2) and has a radius of length 3 What is its equation?
Equation of the circle: (x+1)^2 +(y+3)^2 = 25
When The circle below is centered at the point (-1 -3) and has a radius of length 5. What is its equation?
Equation of the circle: (x+1)^2 +(y+3)^2 = 25
What is the equation of a unit circle?
A unit circle is a circle of radius 1. If it's center is at the origin of an xy-coordinate system, then the equation is x (squared) + y (squared) = 1
What numbers have the absolute value of 1?
All complex number that can be represented by the coordinates of points on the unit circle, that is, the circle with its centre at the origin and a radius of 1 unit.
Which point does not lie on the circle centered at A3 1 and passing through the origin 0 0?
Believe it or not, there are lots of such points.
The circle below is centered at the point (1 2) and has a radius of length 3. What is its equation?
(x-1)^2 + (y-2)^2 = 3^2
What is the equation for a circle centered at the point (-1 3) and has a radius of length 4. What is the equation?
Equation: (x+1)^2 +(y-3)^2 = 16
What is the equation for a circle centered at the point (-13) and has a radius of length 4. What is the equation?
It is (x + 1)2 + (y - 3)2 = 42
