Carbon 14 dating calculus

Since the half-life of Plutonium 239 is so high (even in comparison to the carbon 14 half-life of 5,730 years) humans must be very cautious of the way they dispose of plutonium.

I am just learning the recipe so it takes me more time to look back and forth and double check.

The more cookies I make, the more practice I have and the less time it takes me to bake the cookies.

The half-life of a radioactive isotope describes the amount of time that it takes half of the isotope in a sample to decay.

In the case of radiocarbon dating, the half-life of carbon 14 is 5,730 years.

The kerosene is purified by removing pollutants, using a clay filter.

Suppose the clay is in a pipe and as the kerosene flows through the pipe, every foot of clay removes 20% of the pollutants, leaving 80%.

If the fossil has 35% of its carbon 14 still, then we can substitute values into our equation.

So, the fossil is 8,680 years old, meaning the living organism died 8,680 years ago.

This can be represented as an exponential function if we say that every time I bake cookies my time decreases by 1/5 of the previous time.

We can use exponential decay to represent a number of different things.

Most importantly, exponential decay is not linear and the decrease is rapid at first, but not constant.
