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.

This depends on the length of the needle you are using, the location chosen for the shot, and the size of the person being injected. Flu vaccine is given as an IM (intramuscâ¦ular) injection. For most people, a regular 25 or 22 gauge needle that is one inch or one and one half inches long is the proper size.
