4. A plot of log(N) as given in problem 3 would look like what kind of curve? What is its slope? What is its intercept?
7. In you are given that o is 0.40 (40%) and that c= 0.00005 ft-1.
At what depth (in feet) will the porosity drop to 50% of maximum porosity? Show steps and computations. Offer brief explanations or notes to make sure the reader will know what you are doing.

10. Given the data in part b of problem 9 above, consider the following. If the porosity continued to vary with the same slope observed between 2 and 4 kilometer depths what would the porosity be at the surface (i.e. what is the intercept of a line with the slope determines in part b of problem 9?). Show your computations.
We’re after the intercept – this point
