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.
Simple Interest Example. To illustrate how the simple interest calculation can be used to compute annual interest expense, assume a company issues bonds with a five-year life, a total face value of $100,000 and an annual interest rate of 10 percent with accrual and payment of interest made at the end of each year.
