CAREERS INVOLVING LOGARITHMS
What's a log?
Inverses of exponentials
Types of logs = natural log( base e) and common log (base 10)
Log Rules:
Sneha Suri
MP 4 Assessment
Period 7
CORONERS
HOW DO CORONERS USE LOGS?
ARCHEOLOGY
HOW ARCHEOLOGISTS USE LOGS
WORKS CITED
Public officer whose primary function is to investigate deaths that are not the result of natural causes
Common Investigations:
Homicides
Suicides
Accidents
Responsibilities:
Identification of deceased
Determining cause of death
Classification of type of death
http://www.indy.gov/eGov/County/Coroner/Roles/Pages/home.aspx
Used to determine how long a body has been dead
When a body dies, it begins to cool
To determine how long the body has been dead, the coroner needs to know how long the body temperature was not near 98 degrees
Rate of body cooling is proportionate to body temperature change
Answer found using exponential decay
A scientist who studies human history by digging up human remains and artifacts.
RESPONSIBILITIES:
-cleaning/preserving finds;
- researching
-identifying any possible archaeological impact
-providing advice on the conservation or recording of archaeological remains
-dating and interpreting finds (radiocarbon dating)
-mathematical, statistical and computational modeling

To determine the age of artifacts (bones, fibers)
Dating back to 50,000 years old
When a plant/animal dies, Carbon 14 (isotope of carbon) decays in the atmosphere
Using logs, the decay of carbon 14 can be compared to carbon 12
Carbon 12 remains constant after death, which is how the age is determined/compared.
This method = Radioactive dating
