**Find the equation of the cross-sectional parabola of the dome.**

An engineer designs a satellite dish with a parabolic cross section. The dish is 16 ft wide at the opening, and the focus is placed 6 ft from the vertex. The dish is 16 ft wide at the opening, and the focus is placed 6 ft from the vertex.... In mathematics, a conic section (or simply conic) is a curve obtained as the intersection of the surface of a cone with a plane. The three types of conic section are the hyperbola, the parabola…

**The base of S is the region enclosed by the parabola y = 4**

Exercises Section 1.1 – Volumes Using Cross-Sections 1. The solid lies between planes perpendicular to the x-axis at x = 0 and x = 4. The cross-sections perpendicular to the axis on the interval 04 x are squares whose diagonals run from the parabola yx to the parabola yx . Find the volume of the solid. 2. The solid lies between planes perpendicular to the x-axis at x = 1 and x = 1. The cross...p. 290 (3/23/08) Section 14.2, Horizontal cross sections of graphs and level curves Here is a general deﬁnition of level curves. Deﬁnition 1 The level curves (contour curves) of z = f(x,y) are the curves in the xy-plane where the

**SOLUTION A satellite dish has a parabolic cross section**

20/10/2013 · An old satellite dish antennae was found with diameter 8 feet and the depth of the dish at the center was 18 inches. Find an equation for the parabolic cross section of the dish through the vertex and determine where the focus is at. how to get gta vice city deluxe mod The parabola is the curve formed from all the points (x, y) that are equidistant from the directrix and the focus. The line perpendicular to the directrix and passing through …. How to learn about the tradittiaonl ladnowners of sa

## How To Find The Cross Section Of A Parabola

### Find an equation which models this shape, using the x-axis to represent the ground. State the focus and directrix. State the focus and directrix. For simplicity, I'll center the curve for the arch on the y -axis, so the vertex will be at ( h , k ) = (0, 25) .

- Sketch the solid (or the base of the solid) and a typical cross section. 2. Find a formula for A (x). 3. Find the limits of integration. 4. Integrate A (x) to find the volume. EXAMPLE 1: Find the volume of the solid that lies between planes perpendicular to the x-axis at x = 0 and x = 4. The cross sections perpendicular to the x-axis between these planes run from one side of the parabola x = y
- A satellite dish has a parabolic cross section and is 6 ft deep. The focus is 4 ft from the vertex. Find the width of the satellite dish at the opening. Round your answer to the nearest foot. The focus is …
- s EXAMPLE 1 Find the focus and directrix of the parabola y2 + lox = 0 and sketch X= tor with elliptical cross-section is placed in such a way that the kidney stone is at one focus. High-intensity sound waves generated at the other focus are reflected to the stone and destroy it without damaging surrounding tissue. The patient is spared the trauma of surgery and recovers within a few days
- Setting these equal, squaring and simplifying, we find y 2 = 2px, the equation of the parabola. This is a very useful definition, since we may now use all the power of analytical geometry and calculus to answer any questions we might have about normals, tangents, and so forth.
