6. A population of fish is living in an environment with limited resources. This environment canonly support the population if it contains no more than M fish (otherwise some fish wouldstarve due to an inadequate supply of food, etc.). There is considerable evidence to supportthe theory that, for sorne fish species, there is a minimmum population m such that the specieswill bexzome extinet if the size of the population falls below m. Such a populalion can bemodelled using a modilied logistic equatioa:dPdt(a) Use the differential equation to show that any solution is increasing if m < P< M anddecreasing if 0 < P

We will use the fact , If f(x) is increasing then its derivative f '(x) >0 For direction field…

5.21 There are three resource types available for a certain project. One unit of each resource type is available. The project manager wants to evaluate the project cost on the basis of how resource teams are made up. She has the option of using a resource team, where the team can consist of only one resource type or a combination of resource types. If the team consists of more than one resource type, the resources will start and stop working at the same time. Fractions of a workday are permissive with prorated cost. Resource 1 can complete the project alone in 50 days at a cost of $2,500/day. Resource 2 can complete the project alone in 35 days at a cost of $5,750/day. Resource 3 can complete the project alone in 75 days at a cost of $1,500/day. The resources produce identical quality of work. a) Determine the team composition that will yield the minimum project cost. b) What is the project duration corresponding to that minimum cost? Plot all the project costs versus the respective…

3.7. The formation of algal solutions and other biological colonies in surface waters is strongly dependent on such factors as the pH of the water, the temperature, and oxygen content. Relationships among these various factors enable environmental engineers to study issues involving bioremediation using the algae. Suppose we define a set T of water temperatures from a lake on the following discrete universe of temperatures in degrees Fahrenheit: T = {50, 55, 60}. And suppose we define a universe O of oxygen content values in the water, as percent by volume: O = {1, 2, 6}. Suppose a Cartesian product is performed between specific fuzzy sets T and O defined on T and O to produce the following relation: 1 6. 50 [0.1 0.2 0.9 1 60 | 0.8 0.7 0.1 R = Tx 0 = 55 0.1 0.7 Now suppose we define another fuzzy set of temperatures, "about 55°F," with the following membership values: 0.5 IT = 50 1 0.7 + 55 60 (a) Using max-min composition, find S IT o (T × O). (b) Using max-product composition, find S…
