Question

Animal populations move about and disperse. A number of models for this dispersion have been proposed, and many of them involve the logarithm. For example, in 1965 O. H. Paris† released a large number of pill bugs and after 12 hours recorded the number n of individuals that could be found within r meters from the point of release. He reported that the most satisfactory model for this dispersion is given by the following formula.

n = −0.772 + 0.297 log(r) + 6.991

(a) Make a graph of n against r for the circle around the release point with radius 15 meters.

(b) How many pill bugs were to be found within 1 meter from the release point? (Round your answer to the nearest whole number.)
_______individuals

(c) How far from the release point would you expect to find only a single individual? (Round your answer to two decimal places.)
_______m
