the assignment is written as follows:
A parcel is attracting nervous attention at australian post. the parcel is radioactive and inspectors are trying to identify the material. Suppose they make the following measurements. There are 50 grams of the material and it's decaying at a rate of 0.25 grams per day.
One of the characteristics of radioactive materials is it's half life. That is the time it takes for half the material to decay. Below is a table giving the half-lives of common radioactive elements.
ISOTOPE HALF LIFE
Carbon-14 5730 years
Chlorine-36 301,000 years
Polonium-210 138 days
Phosphorus-32 14.2 days
Iodine-131 8 days
Uranium-238 4.5 x10years
Your task is to identify the material in the box assuming that the isotope will decrease to 25 grams. Using the ideas developed in class, it should be clear that an exponential equation would provide a good model for radioactive decay.
*******************************************
so recently in class we've been learning about derivatives, logs, ln, etcc
please help me with full detail...i have no idea how to do this
THANKSSS
