Algebra A, Homework 6

From Chapter 6, do problems 16 and 22-30.

Some of these problems are pretty easy if one uses the magical
black-box tools of the 21st century - graphing calculators,
computer algebra systems, iPod Nanos, etc.  I think it's much
more informative to explore how one would do these problems
using the tools of 1971, when the book was written - pen and
paper, slide rules, vinyl records by the Rolling Stones, you
know the drill.  After all, the tools of this chapter are among
those uesd to program some of the magical 21st century gadgets.

Let's have these due on November 18.
