- A parabolae plural parabolas or parabola is a two-dimensional, mirror-symmetrical curve. It can be in any orientation in its plane and approximately U-shaped. The parabola calculator to find the vertex, Focus, Directrix, Intercepts of a parabola you enter.
In this problem, given the focus at (-7,5) and directrix at y = -11. then it is implied that the parabola is facing upwards. The vertex hence is at the middle of the focus and the directrix, hence at (-7, -3). The general formula of the parabola is y-k = 4a (x-h)^2. SUbstituting, y + 3 = 1/30 * (x+7)^2.
- This calculator will tell you the critical value of the F-distribution, given the probability level, the numerator degrees of freedom, and the denominator degrees of freedom. Please enter the necessary parameter values, and then click 'Calculate'.

- Feb 07, 2018 · ” Situational problems involving parabolas” 3. Example: A satellite dish on the top of the building has a shape called a paraboloid, where each cross- section is a parabola. Since radio signals (parallel to the axis) will bounce off the surface of the dish to the focus, the receiver should be placed at the focus.

The focus of a parabola is a fixed point on the interior of a parabola used in the formal definition of the curve. Note: For a parabolic mirror, all rays of light emitting from the focus reflect off the parabola and travel parallel to each other (parallel to the axis of symmetry as well).
