Question

Is there any way to remember the Compound Interest formula and Exponential Growth & Decay Formulas? Is there any way to remember the Compound Interest formula and Exponential Growth & Decay Formulas? @Mathematics

Answer 1

X(1+i)^n

Answer 2

For compound interest X(1+i)^n is the general formula

Answer 3

In July 2002, National Geographic ran an article about the problems that America faces with its ever-growing amount of nuclear waste. Currently the United States has over 77,000 tons of waste. Environmentalists talk about how the radioactive material will be dangerous for thousands of years because of its long half-life. In fact, it will take 240,000 years for plutonium 239 to become safe!



When scientists talk about half-life, they are referring to how long it will take for half of a sample to decay. In the case of nuclear waste, it refers to how long it takes for half of the radioactive material to turn into lead.



Exponential growth is very similar, but deals with, you guessed it, growth, instead of decay. The most common example is the growth of bacteria colonies. Bacteria multiply at an alarming rate. If we assume that bacteria can double every hour and if we start with just a single bacteria, then after one day there will be over 16 million bacteria!



Obviously exponential growth, or decay for that matter, cannot continue indefinitely. Eventually there would no longer be any space or nutrients available for the bacteria, or the last atom of plutonium would decay into lead. As a result, exponential growth and decay only refers to the early stages of both processes.

Answer 4

I don't know what you mean by exponential growth and decay formulas

Answer 5

Yes. Write them down 20 times each reciting them aloud as you write. When you go to sleep tonight, repeat them over and over as you are falling asleep. You will know them tomorrow.
