Problem 7: Diffusion. Crossing a membrane by simple diffusion can be distinguished from facilitated diffusion because: If the particles can move through the lipid bilayer by simple diffusion, then there is no limit to the number that can fit through the membrane.
The second way to calculate compound interest is to use a fixed formula. The compound interest formula is ((P*(1+i)^n) - P), where P is the principal, i is the annual interest rate, and n is the number of periods. Using the same information above, enter Principal value into cell A1 and 1000 into cell B1.
Calculator Use. Use this calculator to calculate P, the effective interest rate for each compounding period. P = R/m where R is the annual rate. For example, you want to know the daily periodic rate for a credit card that has 18% annual interest; enter 18% and 365.ompounding Periods (m). is the number of times compounding will occur during a period. Periodic Interest Rate (P). This is the rate per compounding period, such as per month when your period is year and compounding is 12 times per year.
