This is interest that is calculated on both the principal and accrued interest at scheduled intervals. The formula we use to find compound interest is A = P (1 + r/n)^ nt. In this formula, A stands for the total amount that accumulates. P is the original principal; that's the money we start with. The r is the interest rate. We convert the percent to a decimal for this one.
Ingredients in the flu shot. With all of the different flu vaccines on the market, the ingredient list varies a little from shot to shot.

The 2008/2009 influenza vaccine was made in the summer of '08 based on predictions made at the beginning of 2008, over a year ago. The vaccine contains, and therefore provides protection against, 3 strains of influenza, none of which correspond to the new swine flu, which has appeared in an unpredictable fashion. But it's too early to say whether or not the vaccine might offer some protection either against getting infected or against getting very sick.
