Hi Gang,
I hope all went well with Mr. Langridge on Tuesday. I know that logs is all new for most of you but I think you will get along just fine with them.
Here is a site that you might want to check out. TheMathPage would be worth exploring over the space of the next few days.

Mr. Ledet,
I was finishing up 2.4 today, and I came across a few questions that I was unable to do. They all involved half life. I was wondering if there was an equation for it that I didn't learn? The q's are 20-23, 25, 26, 27, and 28...
The key to half life is that you start with 100% of the material and that the amount of radioactive "stuff" is decreasing by 50%, leaving you with 50%. So, the equation that might help you out is
A=100(.5)^(t/h) where t is the elapsed time and h is the half life.
Keep up the great work!
