no

map makers 
builders

e.mccormick · Answer

Yes, for scale on a map or plans for both or for a builder to also estimate how much is needed in materials. This site has an example with heart rate: http://www.ck12.org/algebra/Solving-Real-World-Problems-with-Two-Step-Equations/ This one show sales and insurance: https://ecsd-fl.schoolloop.com/MA912A35 All of those are two step.

e.mccormick · Answer

I don't know if you have seen any basic physics, but velocity and postion use exponents.  It has to do with the fact that things are measured in values like meters per second squared.

e.mccormick · Answer

And then both velocity stuff and time comes into quadratics. Then you get things like the arc of something thrown, which is one of the examples here: http://www.mathsisfun.com/algebra/quadratic-equation-real-world.html

e.mccormick · Answer

So that should give you some references to use for real world applications.
