The parabola is **the locus of points in that plane that are equidistant from both the directrix and the focus**. Another description of a parabola is as a conic section, created from the intersection of a right circular conical surface and a plane parallel to another plane that is tangential to the conical surface.

Parabolas are frequently used in physics and engineering for things such as **the design of automobile headlight reflectors and the paths of ballistic missiles**. Parabolas are frequently encountered as graphs of quadratic functions, including the very common equation y=x2 y = x 2 .

The parabola is **the locus of points in that plane that are equidistant from both the directrix and the focus**. Another description of a parabola is as a conic section, created from the intersection of a right circular conical surface and a plane parallel to another plane that is tangential to the conical surface.

In order to find the focus of a parabola, you must know that the equation of a parabola in a vertex form is **y=a(x−h)2+k** where a represents the slope of the equation. From the formula, we can see that the coordinates for the focus of the parabola is (h, k+1/4a).

In the case of U-shaped Slinky with equal-height sus- pension points, we obtained its shape and showed that **it was a parabola**.

Even though parabolas and hyperbolas look very similar, parabolas are formed by the distance from a point and the distance to a line being the same. Therefore, **parabolas don't have asymptotes**.

The term “parabolic move” came about as trader slang. It refers to **when a stock makes an upward price move that looks like the right side of a parabolic curve**: A parabolic move occurs when the speed at which the stock's price goes up increases exponentially.

**Yes, a full rainbow is a parabola**. As the image shows, a full rainbow is the shape of an upside-down U.

**Examples of Parabola**

- Shape of a Banana. The curved shape of a banana closely resembles a parabola.
- Roller Coasters. The curves of a roller coaster track can be easily observed and compared with the shape of a parabola.
- Bridges.
- Arch.
- Slinky Toy.
- Brand Name Logos.
- Rainbow.
- Wheel Pose.

**Dolphins jump in a parabola shape**.

**The part of the headset that goes over our heads is parabolic** because of its curved shape, and that it opens downward. Just like how some parabolas that go around at the top/bottom and then downward/upward this handle looks the same.

The graphs of quadratic functions are called parabolas. Here are some examples of parabolas. All parabolas are **vaguely “U” shaped** and they will have a highest or lowest point that is called the vertex. Parabolas may open up or down and may or may not have x -intercepts and they will always have a single y -intercept.

By making a connection between the equation of a parabola and a real world shape (the parabaloid), **students are able to find the missing link between the Mathematics of the classroom and real world objects**. In so doing, they can conceptualize complex concepts they might otherwise detest.

**All parabolas are not functions**. Only parabolas that open upwards or downwards are considered functions. Parabolas that open left or right are not considered parabolas. You can test whether or not a parabola is considered a function by conducting the "Vertical Line Test."

The Golden Gate bridge is very popular in the bay area, and many people have traveled over it at one point. Everyone that lives near the bay area knows about this bridge, and **it has a large parabola stretched across the whole bridge**. The point (0,0) is the vertex of the function.

Parabolas can, in fact, be seen everywhere, in nature as well as manmade items. Consider **a fountain**. The water shot into the air by the fountain falls back in a parabolic path. A ball thrown into the air also follows a parabolic path.

When a coaster falls from the peak (vertex) of the parabola, it is rejecting air resistance, and all the bodies are falling at the same rate. The only force here is gravity. Most people (I am NOT included) enjoy or get a thrill out of **parabolic-shaped coasters** because of the intense pull of gravity.

**Hyperbolas in Real Life**

- A guitar is an example of hyperbola as its sides form hyperbola.
- Dulles Airport has a design of hyperbolic parabolic.
- Gear Transmission having pair of hyperbolic gears.
- The Kobe Port Tower has hourglass shape, that means it has two hyperbolas.

Matching questions have a content area and a list of names or statements which must be correctly matched against another list of names or statements. For example "**Match the Capital with the Country" with the two lists "Canada, Italy, Japan" and "Ottawa, Rome, Tokyo"**.

Materials used to make synthetic fibers can be used to make plastics, but not all materials used in making plastics can be used for synthetic fibers. Most fibers are made from compounds that form long polymer strands, e.g., nylon and dacron. **A plastic is generally a synthetic polymer that can be melt processed**.

Biology and Biology majors are hard because of the vast amount of information required to learn but also involves a lot of unfamiliar concepts (some of which are difficult) and require mastering an unfamiliar vocabulary (which is true of any science).
