...LSP 121 Homework 5: Logs and Richter Scale, Decibels Open the file logs.xls (found on the QRC website under Excel Files). You will use this file for both parts below. Click on the worksheet tabs at the bottom to access the other file. 1. Richter scale The Richter scale is used to measure the intensity of earthquakes. It is a logarithmic relationship with the following formula: R = log(I) I is the intensity of the earthquake and R is the number on the Richter scale. (Remember that if there is no base written with the log it is base 10). Don’t be scared off by logs. Think of them as a short-cut way of writing large numbers. For example, let’s say the intensity of an earthquake is 100,000,000. Can you imagine if the papers published that big number? What would people think? Most people cannot handle well numbers with large amounts of zeros (unless those people work for the government ;-). Instead of writing 100,000,000, let’s just write how many zeros there are. In this case, there are 8 zeros. That’s exactly what log10 is asking. 10 to what power equals 100,000,000? 10 to the 8th power. So the log(100,000,000) equals 8. Thus, the Richter value for an earthquake with intensity 100,000,000 is 8. Let’s say it another way. Let’s remove the log. Converting the above formula from log form to exponent form would give us: 10R = I (Note: 10 was raised to the R power, which cancels the log function.) Which version you use depends on which variable you...

...Most of the functions we have studied have been polynomial or rational functions, with a few others involving roots of polynomial or rational functions. Functions that can be expressed in terms of addition, subtraction, multiplication, division, and the taking of roots of variables and constants are called algebraic functions. In exponential & logarithmic functions we introduce and investigate the properties of exponential functions and Logarithmic functions. These functions are not algebraic; they belong to the class of transcendental functions. Exponential and logarithmic functions are used to model a variety of realworld phenomena: growth of populations of people, animals, and bacteria; radioactive decay; epidemics; absorption of light as it passes through air, water, or glass; magnitudes of sounds and earthquakes. We consider applications in these areas plus many more in the sections very important. As a part of our BBA course, we are required to submit a term paper for every subject each semester. As our Advance Business Mathematics faculty Associate Professor Lt. Col. Md. Showkat Ali has asked us to submit a term paper on a topic upon our will. So, we have decided to choose “Exponential & Logarithmic Functions”. to graph exponential functions to evaluate functions with base e to learn the use of compound interest formulas to learn the changing from logarithmic to exponential form to learn the changing from exponential...

...nothing more than an exponent. The basic concept of logarithms can be expressed as a shortcut…….. Multiplication is a shortcut for Addition: 3 x 5 means 5 + 5 + 5 Exponents are a shortcut for Multiplication: 4^3 means 4 x 4 x 4 Logarithms are a shortcut for Exponents: 10^2 = 100. The present definition of the logarithm is the exponent or power to which a stated number, called the base, is raised to yield a specific number. The logarithm of 100 to the base 10 is 2. This is written: log10 (100) = 2. Before pocket calculators — only three decades ago, but in “student years” that’s the age of dinosaurs — the answer was simple. You needed logs to compute most powers and roots with fair accuracy; even multiplying and dividing most numbers were easier with logs. Every decent algebra books had pages and pages of log tables at the back. The invention of logs in the early 1600s fueled the scientific revolution. Back...

It is freely available in its entirety in a downloadable PDF form or to be read online at: http://www.phy.duke.edu/∼rgb/Class/intro physics 1.php It is also available in an inexpensive (really!) print version via Lulu press here: http://www.lulu.com/shop/product-21186588.html where readers/users can voluntarily help support or reward the author by purchasing either this paper copy or one of the even more inexpensive electronic copies. By making the book available in these various media at a cost ranging from free to cheap, I enable the text can be used by students all over the world where each student can pay (or not) according to their means. Nevertheless, I am hoping that students who truly find this work useful will purchase a copy through Lulu or a bookseller (when the latter option becomes available), if only to help subsidize me while I continue to write inexpensive textbooks in physics or other subjects. This textbook is organized for ease of presentation and ease of learning. In particular, they are...
