6a) Let A be the parabolic arc defined by the equation y = 8x – x´ over the domain interval [0, 8]. Sketch A on a set of coordinate axes below; identify the coordinates of both intercepts and the vertex. Estimate the length of A using the lengths of the two line segments joining either intercept to the vertex. b) Write the definite integral that represents the exact length of A. Do not evaluate this integral - just set it up and simplify it. Then, use technology to obtain an estimate of this integral's value. (report it correct to the thousandths place)

Vertices Of An Ellipse

In the study of the conic section of the geometry, An ellipse is a plane curve surrounding two focal points, or foci where the set of all locus of points in the plane has their sum of the distances to the two foci is constant. On the ellipse curve, it is the intersection point of the main axis. In an ellipse graph, the center of the axis is the midpoint of the line segment connecting the foci. The major axis is the line section that runs through the ellipse's foci, while the minor axis runs through the middle and is perpendicular to the major axis.. The ellipse has two endpoints on the major axis which are known as the vertices (in plural), vertex in the singular. The equation of the major axis is 2a, the equation of the minor is 2b and the distance between the major axis and minor axis is 2c. The semi-major axis has a length of a and the semi-minor axis has a length of b. The ellipse's vertices are determined by the elliptical orbit's equation and graph.
