Exponential Growth and Decay  Problem 8
Explanation
One of the most applicable uses of natural logs is Newton's Law of Cooling, which can help you predict how long it will take for something to cool to a certain temperature. If we know the ambient, or surrounding, temperature, and we know information about the starting and ending temperatures, we can use the natural log to tell us how long the cooling will take. Use the "ln" button, or log base "e" to solve for the unknown quantity.
