Iron Bridge at Coalbrookdale

Parabola Project

Anisha K.


Anisha - Please read Section 9-7 and use Example 1 to help find your equation. You will need to find the following information through online research: the bridge span or length, the heights of the towers, and the distance from the road to the parabola at the highest point. Good luck!

Here's a problem you can use for the "Solutions" part of the project. You can use the quadratic formula, or another method if you like.
  • Let's say a boat is floating down the river. The boat has a flagpole on it that is exactly 25 feet tall. How far away from the edge of the bridge should be boat be in order to touch the bridge with the flagpole? In other words, when is your y value equal to 25?
