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.
Formula for Compound Interest. Compound interest is a great thing when you are earning it! Compound interest is when a bank pays interest on both the principal (the original amount of money) and the interest an account has already earned. To calculate compound interest use the formula below.
