Chapter 3.3, Problem 66E
Under certain circumstances a rumor spreads according to the equation
where p(t) is the proportion of the population that knows the rumor at time t and a and k are positive constants.
- (a) Find limt→∞ p(t).
- (b) Find the rate of spread of the rumor.
- (c) Graph p for the case a = 10, k = 0.5, with t measured in hours. Use the graph to estimate how long it will take for 80% of the population to hear the rumor.

- 1. A vertical line segment of length 8 ft is moving horizontally at a rate of 3 ft/sec. At what rate is areabeing swept out by the moving vertical segment? Consider the area formed by the line f(x) = mx, the x axis, and the vertical segment at location x.The vertical segment is moving to the right at 3 ft/sec. At a certain time, say t = T, the height of thevertical segment is 8 ft. At t = T is the area of the triangle increasing at a rate equal to, or greater than, the rate area isswept by the segment in Problem 1? (Ok to guess here). Let A(x) be the area of the triangle.

How rapidly is the radius of the spill increasing when the radius is 2 miles? b)When air expands adiabatically (without gaining or losing heat), its pressure P and volume V are related by the equation PV1.4 = C, where C is a constant. Suppose that at a certain instant the volume is 400 cm3and the pressure is 80kPa and is decreasing at a rate of 10KPa/min.

Letting c(t) be the concentration of salt at time t, show that the limiting concentration–i.e., limt→∞ c(t)–is 0.5 lb/gal. (1) Set up an initial value problem using the situation described above.
