Math 155-004, Quiz 1 January 27, 2008 NAME: Instructions: This quiz is closed books and closed notes. You may use calculators. Work that is erased or crossed out will not be graded. 1. (5 pts) Suppose that a baby grows (in volume) by 2 cm3 /week. Given that 1 week = 7 days, 1 day = 24 hours, and 1 in = 2.54 cm, how fast is the baby growing in in3 /hour? Write out conversion factors and show your work for full and partial credit. 2. [Section 1.2, Ex. 53] (5 pts) The number of mosquitos (M ) that end up in a room is a function of how much the window is open (W , in cm2 ) according to M (W ) = 5W + 2. The number of bites (B) you get depends on the number of mosquitos by B(M ) = 0.5M . Find the number of bites you get as a function of how much the window is open. Extra Credit: The reading was about group behavior and how simple rules guide flocks/groups/swarms. Name two of the animals that were studied (and discussed in the article) to explore this group behavior.
