sec 5.3 Homework 4 a,c,e

Hi guys,

So I went through these questions today after school, and wanted to show you a faster, easier way to work through them.  So 4a and 4c, are quick, exact solutions using the equations only and 4e is an explanation based on what we did in class today, using a table and a graph.

So here is 4a.  I was just using the computer's built in mic so it's pretty quiet on this one.  The rest will be louder.



Here is 4c.  I think you'll find the volume a little louderat least,  if not better.



Finally, here is 4e.  In this one I used the table of values and a graph to get an estimate of the value of x that makes the equation true.  This one is a little longer.
