Consider the points P such that the distance from P to 1, 5, 3) is twice the distance from P to B(6, 2, —2). Show that the set of all such points is a sphere, and find its center and radius. Find an equation of the set of all points equidistant from the points A(— 1, 5, 3) and B(6, 2, —2). Describe the set.Circle formula. The set of all points in a plane that are equidistant from a fixed point, defined as the center, is called a circle. Formulas involving circles often contain a mathematical constant, pi, denoted as π; π ≈ 3.14159. π is defined as the ratio of the circumference of a circle to its diameter.

Definition of a Parabola . The parabola is defined as the locus of a point which moves so that it is always the same distance from a fixed point (called the focus) and a given line (called the directrix). [The word locus means the set of points satisfying a given condition. See some background in Distance from a Point to a Line.]. In the following graph,

For points and of the coordinates plane, a new distance d (P,Q) is defined by . Let and . Consider the set of points P in the first quadrant which are equidistant (with respect to the new distance) from O and A. <br> The area of the ragion bounded by the locus of P and the line in the first quadrant is

The equation to find the amount that Carmen earns each week is y = 0.17 x + 15 . Substitute x = 300 in the equation y = 0.17 x + 15. Thus, Carmen will earn $66.

A circle is the set of all points in a plane that are equidistant from a given point called the center of the circle. We use the symbol to represent a circle. The a line segment from the center of the circle to any point on the circle is a radius of the circle. hope i help =)

equation of the tangent line at (x 0;f(x 0)) using the point-slope formula: y f(x 0) = f0(x 0)(x x 0): To solve for the xintercept we set y= 0 and rearrange terms to get f(x 0) = f0(x 0)(x x 0) 1Often called the orbit of x 0. 2Formally de ned in Section 6, a Basin of Attraction is the set of points which converge to a particular root.

Find the point(s) of intersection, if any, between each circle and line with the equations given. 62/87,21 Graph these equations on the same coordinate plane. ( x ± 1)2 + y2 = 4 is a circle with center (1, 0) and a radius of 2. Draw a line through (0, 1) with a slope of 1 for y = x The points of intersection are solutions of both equations.

The line segment starting from the center of the graph going to the right (called the positive x-axis in the Cartesian system) is the polar axis.The center point is the pole, or origin, of the coordinate system, and corresponds to r = 0. r = 0. The innermost circle shown in Figure 7.28 contains all points a distance of 1 unit from the pole, and is represented by the equation r = 1. r = 1.

Hi. This lesson covers a few examples of the parametric form of the equation of a straight line.. Example 1 Find the coordinates of the points on the line 3x - 4y + 1 = 0 at a distance of 5 units from the point A(1, 1). Solution First, let me illustrate a method of finding out the required coordinates without using the parametric form.. If the coordinates of the required point be (x 1, y 1 ...
