If you look at every individual line of this Fire Wheel, you can see how each spark is following a quadratic equation. It would be possible to write an equation for one of these sparks and identify its maximum height and position it will land on the ground.
This video walks you through an example of how to maximize area of a three sided shape with a given perimeter. Refers to Changing to Vertex Form Video http:/...
Find when a thrown ball reaches a specific height using a quadratic function and factoring - includes the graph of the quadratic function
This video show different situations were you can see a quadratic equation used in real life. It also goes into explaining the reason and information you could need to find about a quadratic function.
