Equation of circle: x^2 +y^2 -2x -6y +5 = 0
Completing the squares: (x-1)^2 +(y-3)^2 = 5
Center of circle: (1, 3)
Tangent contact point: (3, 4)
Slope of radius: ((3-4)/(1-3) = 1/2
Slope of tangent line: -2
Equation of tangent line: y-4 = -2(x-3) => y = -2x+10
Equation tangent rearranged: 2x+y = 10
When y equals 0 then x = 5 or (5, 0) as a coordinate
Distance from (5, 0) to (1, 3) = 5 using the distance formula
The radius of a circle is defined as the distance from the centre-point to the circumference.
Equation of circle: x^2 +y^2 -2x -6y +5 = 0 Completing the squares: (x-1)^2 +(y-3)^2 = 5 Center of circle: (1, 3) Tangent line from (3, 4) meets the x axis at: (5, 0) Distance from (5, 0) to (1, 3) = 5 using the distance formula
It works out that the circle's centre is at (3, -2) and its radius is 5 on the Cartesian plane.
From the centre of Albury to the centre of Wodonga is a distance of 5.53km.
Centre of the circle is at (7, 7) and its Cartesian equation is (x-7)^2 + (y-7)^2 = 49
Circle equation: x^2 +y^2 -2x -6y +5 = 0 Completing the squares: (x-1)^2 +(y-3)^2 = 5 Centre of circle: (1, 3) Tangent line meets the x-axis at: (0, 5) Distance from (0, 5) to (1, 3) = 5 units using the distance formula
work done is zero because force is toward the centre and distance is tangent to the circle so cos90 is equal to zero.[abbasia]
The immediate surroundings of any point on a curved path can be considered as part of a circle: the circle of curvature at that point. Then the tangent to the path at that point is a line that meets the path at only one point in that neighbourhood and which is perpendicular to the line joining the point to the centre of the circle or curvature. The concept can be extended to straight segments of the path by assuming that the centre of curvature is at an infinite distance. In that case, the path and its tangent are the same line.
You maybe referring to the diameter of a circle or its tangent
Centre of circle: (3, -5) Distance from (3, -5) to (6, -7) is the square root of 13 which is the radius Equation of the circle: (x-3)^2 + (y+5)^2 = 13
A tangent to a circle is a line which touches the circle once. That is, it does not pass through the circle, which would mean intersecting it twice. A way to form a tangent is draw any line from the centre point of a circle to its edge. A line on the edge perpendicular (at 90 degrees to) this line will be a tangent.
The average centre-to-centre distance from the Earth to the Moon is 384,403 km
