# What is an example of an exponential function used in the real world today?

## What is an example of an exponential function used in the real world today?

Compound interest, loudness of sound, population increase, population decrease or radioactive decay are all applications of exponential functions.

### How can exponents and scientific notation be used in real life?

Writing Large or Small Numbers Sometimes scientists must use exceptionally large or small numbers. Scientific notation relies on exponents to write these numbers in a simpler way. For example, the large number 21,492 is 2.1492 x 104 in scientific notation.

How can scientific notation be used in the real world?

Scientific notation is used to write very large or very small numbers using less digits. See how scientists use this notation to describe astronomical distances, such as the distance between planets, or microscopic distances, such as the length of a blood cell. …

What is a real life example of scientific notation?

For example, the 65,000,000,000 cost of Hurricane Sandy is written in scientific notation as \begin{align*}\6.5 \times 10^{10}\end{align*}. Why is scientific notation important? You’re less likely to make mistakes reading or writing very big and very small numbers if you use scientific notation.

## How are exponential functions used in the real world?

Site Navigation. Applications of Exponential Functions. The best thing about exponential functions is that they are so useful in real world situations. Exponential functions are used to model populations, carbon date artifacts, help coroners determine time of death, compute investments, as well as many other applications.

### When to use scientific notation in the real world?

Scientific Notation is also used for expressing very small decimal values like the size of flu virus molecules, or the distance between atoms in a crystal structure. An online presentation of this lesson is available on SlideShare at the following Link:

How is the world population represented in scientific notation?

If the decimal is shifted to the right, the exponent n is negative. The world population is nearly 7000,000,000. To represent the given number in scientific notation, we have to move the decimal point 9 digits towards left side. So, the power of 10 will be positive. We have to move the decimal point 15 digits towards left side.

How is the power of 10 represented in scientific notation?

To represent the given number in scientific notation, we have to move the decimal point 9 digits towards left side. So, the power of 10 will be positive. We have to move the decimal point 15 digits towards left side. So, the power of 10 will be positive. 0.000 000 000 000 000 000 000 000 000 00091093822 kg.
