Exponential And Logarithmic Functions

Suppose you open an account that pays a guaranteed interest rate, compounded annually. You make no further contributions; you just leave your money alone and let compound interest work its magic.

The balance your account has grown to at some point in the future is known as the future value of your starting principal.

To find a formula for future value, we'll write P for your starting principal, and r for the rate of return expressed as a decimal.

Your balance will grow according to the following schedule:

1. FV = P (1 + r)Y

That's to compound once per year. More generally, if you want to compound n times per year, you use:

2. FV = P (1 + r / n)Yn

Population growth inThe model of populational growth, the variables within a country are the births and the death rate. It is also diferent between third world countries and first world . the first wold countries have les growth and less death death rates,. third world ones have more growth and earlier rates.The mathematical model  The relationship between the exponentional function and the logarithmic one is proportional to the real life one. 

You must use 2 variables and one constant.

The first variable is height of the jump.

The second variable is air resistance.

The constant is gravity 9.8m/s
