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.
If the interest is calculated once a year then the interest is called âsimpl e interestâ. If the interest is calculated more than once per year, then it is called âcompound interestâ. Compound Interest Formula The mathematical formula for calculating compound interest depends on several factors.
