Question 783984: I need help with rational expressions applications?
I need to find an application and formulate two to three values for your application and state your results also Provide an explanation of your application and its values in your main post.
The example I was shown to make it resemble is:
The rational function C(t) = 0.18t / (t^2 + 3) can describe the concentration of a drug in the body of a patient after t hours.
This function has a maximum at sqrt(3), and trails off to zero as t gets large.
We can interpret this as the drug entering the body for the first hour and a half or so, then the body starting to flush the drug out as the concentration grows. At time t = sqrt(3), the flushing starts to overcome the entry, and the concentration begins to decrease. We see that the flushing is at the maximum rate at t = 3, and then starts to slow down. The body slowly removes any remaining concentration over a longer period of time.
So I need some help finding something like this I am having no luck and its making me feel like a scientist with a brain that isn't working

You can put this solution on YOUR website!

Try this:

A business is studying the cost to remove a pollutant from the ground at its site. The function models the estimated cost (in thousands of dollars) to remove percent (expressed as a decimal) of the pollutant.

You will need to establish a reasonable domain for this function considering that you can't remove a negative amount of pollution and you can't remove more than all of it (100% = 1.00).

And be careful. Scientists with brains that don't work tend to believe in Intelligent Design.
