What are the four regions created by the intersection of the horizontal and vertical number lines in a coordinate plane?
What are the four regions created by the intersection of the horizontal and vertical number lines in a coordinate plane?
The number lines intersect at the origin and separate the coordinate plane into four regions called quadrants.
What is divided into four regions by the X and Y-axes?
The x- and y-axes divide the coordinate plane into four regions. These regions are called quadrants.
What are the four regions a coordinate plane is divided into called?
The coordinate axes divide the plane into four regions called quadrants. The quadrants are numbered I, II, III, and IV as shown on the grid below.
What is difference between ordinate and abscissa explain with an example?
Answer: In the coordinate system, the ordinate is the second component of an ordered pair. For example, if (x, y) is an ordered pair, then y is the ordinate here. An ordered pair is used to denote a point in the Cartesian plane and the first coordinate (x), in the plane, is called the abscissa.
What is the length of double ordinate?
Thus we got the length of the double ordinate as 16√3. ∴Option (c) is the correct answer. Note: The double ordinate of parabola is any chord which is perpendicular to the axis of parabola. Here PA and P’A are the two chords which are perpendicular to the axis of the parabola, that’s why it is called a double ordinate.
What is ellipse and its properties?
An ellipse is formed by a plane intersecting a cone at an angle to its base. All ellipses have two focal points, or foci. The sum of the distances from every point on the ellipse to the two foci is a constant. All ellipses have eccentricity values greater than or equal to zero, and less than one.
What is an ellipse class 11?
An ellipse is the locus of all those points in a plane such that the sum of their distances from two fixed points in the plane, is constant. The fixed line is directrix and the constant ratio is eccentricity of ellipse.
What is the diameter of an ellipse?
Mathwords: Major Diameter of an Ellipse. The segment joining the vertices of an ellipse, or the length of that segment. The major diameter passes through the center and foci. It is an ellipse’s longest diameter.
How do you find the major diameter of an ellipse?
The major axis is the longest diameter of an ellipse. Suppose the equation of the ellipse be x2a2 + y2b2 = 1 then, from the above figure we observe that the line-segment AA’ is the major axis along the x-axis of the ellipse and it’s length = 2a. Therefore, the distance AA’ = 2a.
