A certain coral reef is home to a population of hammerhead sharks. Following the implementation of a preservation program, scientists track the shark population over 10 years and obtain the following data: (a) Based on this data collection, approximate the carrying capacity of the population. (b) Assuming that this population follows the trend of a logistic growth model with a growth rate of 0.2, write a differential equation to represent the rate of change of number of sharks per year. dP dt = (c) Construct a phase line for your differential equation. (d) Does the carrying capacity you identified represent a stable unstable or semistable equilibrium solution?

An arbitrarily curved wire that carries a current between two endpoints in the presence of a uniform magnetic field will experience the same net magnetic force as a straight wire carrying the same current between the same endpoints. Essentially, any forces experienced by parts of the wire that curve or twist away from the straight-line path are canceled out by forces on sections that curve back toward the original path. Furthermore, if the wire forms a closed loop in between the endpoints, the net force on the closed loop is zero. Using this result, consider a town where the Earth's magnetic field has a magnitude of 51.3 μT. The magnetic field vector lies in a vertical plane defined by the north-south and up-down axes, and it points 60.0∘ below the northward direction. In this town, a storefront window lies along the north-south vertical plane, and in the window is a neon sign (which is a thin current-carrying discharge tube). The sign carries a 35.1 mA current, starting from the lower south corner of the window, and ending at the opposite corner, which is 1.32 m to the north and 0.850 m upward. The sign spells out the word "BURGERS" between the two points. What is the net vector magnetic force (in μN ) on the neon sign? (Take east to be the +x-axis, up to be the +y-axis, and south to be the +z-axis. Do not include units in your answer.) F→B = μN

Recall that a logistic growth model takes the form dP dt = rP(1 − P K) where r is some growth or decay constant, P is the number in the population, and K is the carrying capacity. Suppose data has been collected on the population counts of different types of fish in Horsetooth Lake, and is shown below: Scientists suspect that these populations follow a logistic growth model. They know that Horsetooth's carrying capacity for Walleye is 500 fish, the carrying capacity for Bluegill is 600 fish, and the carrying capacity for small-mouth bass is 1000 fish. (a) Determine the growth/decay constant (r) for one of the species of fish using the data provided. Specify which species you have chosen. (hint: recall the form that the solution to a logistic growth model takes, and use log rules to isolate r!)
