Textbook Question
Chapter 13, Problem 1RQ
An environmental engineer has obtained a bacteria culture from a municipal water sample and has allowed the bacteria to grow.
- a. Show the resulting data and trendline, with equation and R2 value, on the appropriate graph type (xy scatter, semilog, or log–log) to make the data appear linear.
- b. Assume the value of m in the resulting model is the growth constant. Use the trendline determined to find the value and units of the growth constant for these bacteria.

As the potential across the resistor increased, the current through the resistor increased. If the change in current is proportional to the voltage, the data should be in a straight line and it should go through zero. In these two examples how close is the y-intercept to zero? Is there a proportional relationship between voltage and current? If so, write the equation for each run in the form potential = constant x current. (Use a numerical value for the constant.)
In your biomechanical testing lab, you perform a series of compression tests to determine the relationship
between apparent bone density (p, units of g/cm³) and ultimate stress (ơult, units of MPa). Using the set of
experimental measurements below, write an m-file to fit a power relationship of the form
O uli = Ap
to the data. Use the log transform method to linearize the system and data, followed by linear regression.
Plot the data points and the power relationship on a single plot. Be sure to label your axes and provide a
legend. Provide a printout of your m-file and a printout of the command window showing your results.
Write down the best fit equation and box it.
