When the sunlight shines on auto exhausts, certain pollutants are produced that can be unsafe to breathe. In a study done of runners of many ages and levels of training, it has been shown that a level of 0.3 parts per million (ppm) of pollutants in the air can cause adverse effects. Though the level of pollution varies from day to day and even hour to hour, it has been shown that the level during the summer can be approximated by the model 25 . 0 16 . 0 04 . 0 2 + = t t L , where L measures the level of pollution and t measures time with t = 0 corresponding to 6:00 a.m. When will the level of pollution be at a minimum? What time of day should runners exercise in order to be at a safe level? 1) The level of pollution will be at a minimum at 8 a.m. The pollution levels will be below 0.3 ppm between 6 a.m. and 10:17 a.m.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
