                            a.            1.000 ppm                             b.            3.178 ppm                             c.            3.358 ppm                             d.            6.717 ppm                             e.            0.360 ppm Assume that an environmental study indicates that the average daily level p of a certain pollutant in the air, in parts per million (ppm), can be modeled by the equation p = 0.6 0.36n2 + 6n + 36 where n is the number of residents of the community, in thousands. Find the rate at which the level of pollutant is increasing when the population of the community is 16,000. Round your answer to three decimal places.

Explanation / Answer

dp/dn= 0.6x(0.36x2n+6) / (2xsqrt(0.36n^2 + 6n+36))

keeping n=16000

we get answer = 0.35999 ppm

which is e
