Rewriting and solving a real-world exponential model
The amount of energy released from one earthquake was 500 times greater than the amount of energy released from another. The equation
represents this situation, where
is the difference in magnitudes on the Richter Scale. To the nearest thousandth, what was the difference in magnitudes?
We begin by rewriting the exponential equation in logarithmic form.
Next we evaluate the logarithm using a calculator:
The amount of energy released from one earthquake was
times greater than the amount of energy released from another. The equation
represents this situation, where
is the difference in magnitudes on the Richter Scale. To the nearest thousandth, what was the difference in magnitudes?
The most frequently used base for logarithms is
Base
logarithms are important in calculus and some scientific applications; they are called
natural logarithms . The base
logarithm,
has its own notation,
Most values of
can be found only using a calculator. The major exception is that, because the logarithm of 1 is always 0 in any base,
For other natural logarithms, we can use the
key that can be found on most scientific calculators. We can also find the natural logarithm of any power of
using the inverse property of logarithms.
Definition of the natural logarithm
A
natural logarithm is a logarithm with base
We write
simply as
The natural logarithm of a positive number
satisfies the following definition.
For
We read
as, “the logarithm with base
of
” or “the natural logarithm of
”
The logarithm
is the exponent to which
must be raised to get
Since the functions
and
are inverse functions,
for all
and
for
Given a natural logarithm with the form
evaluate it using a calculator.
The lymphatic system plays several crucial roles in the human body, functioning as a key component of the immune system and contributing to the maintenance of fluid balance. Its main functions include:
1. Immune Response: The lymphatic system produces and transports lymphocytes, which are a type of
asegid
to transport fluids fats proteins and lymphocytes to the blood stream as lymph
Anatomy is the study of the structure of the body, while physiology is the study of the function of the body. Anatomy looks at the body's organs and systems, while physiology looks at how those organs and systems work together to keep the body functioning.
Enzymes are proteins that help speed up chemical reactions in our bodies. Enzymes are essential for digestion, liver function and much more. Too much or too little of a certain enzyme can cause health problems

the normal temperature is 37°c or 98.6 °Fahrenheit is important for maintaining the homeostasis in the body
the body regular this temperature through the process called thermoregulation which involves brain skin muscle and other organ working together to maintain stable internal temperature
