Given focus and directrix find parabola

WebThe given focus of the parabola is (a, 0) = (4, 0)., and a = 4. For the parabola having the x-axis as the axis and the origin as the vertex, the equation of the parabola is y 2 = 4ax. Hence the equation of the parabola is y 2 = 4 (4)x, or y 2 = 16x. Therefore, the equation of the parabola is y 2 = 16x. Example 2: Find the focus of the parabola ... WebKey Concepts. A parabola is the set of all points (x, y) in a plane that are the same distance from a fixed line, called the directrix, and a fixed point (the focus) not on the directrix. The standard form of a parabola with vertex (0, 0) and the x -axis as its axis of symmetry can be used to graph the parabola.

WebNames. Here are the important names: the directrix and focus (explained above) the axis of symmetry (goes through the focus, at right angles to the directrix); the vertex (where the parabola makes its sharpest turn) is halfway between the focus and directrix. Reflector. And a parabola has this amazing property: Any ray parallel to the axis of symmetry gets … WebThe parabola is downward-facing and its vertex is at the midpoint between the focus and the directrix. Using the formula for the distance from a point to a line, the distance from the point (3,−5) to the line y=−11 is: d = −5− (−11) /sqrt (1) = 6. This distance is also the distance from the vertex to the focus (or directrix), so the ... etele pláza nyomtatás https://tommyvadell.com

WebApr 11, 2024 · Illustration 4: Find the coordinates of the focus, the axis of the parabola, the equation of directrix and the length of the latus rectum for y 2 = 12x. Solution: The given equation is y 2 = 12x. Here, the coefficient of x is positive. Hence, the parabola opens towards the right. On comparing this equation with y 2 = 4ax, we get 4a = 12 or a = 3. Web1 answer. Since the directrix is a vertical line of the form x=a, the parabola is vertical and opens either upward or downward. The vertex is halfway between the focus and the directrix, which is at the point (3,-4). The distance from the focus to the vertex is the same as the distance from the vertex to the directrix, which is 1.
