First order of business today was Algebra. I learned about exponential growth and decay. So, when a quantity decreases by a fix percent over a period of time, the amount y of that quantity after t time is given by:

ya(1 – r)t, where a is the initial amount, and r is the percent of decrease expressed as a decimal. In this case, r can also be called the rate of decay. However, if you change that equation so that the subtraction is instead addition, it is the formula for exponential growth instead of exponential decay. In that case, r is the rate of growth.


Next, English. I continued working on my paper, selecting specific topics from my sources to use in my essay.


As for other things, I’ve suspended some classes so that I can focus on my english paper.
