Circadian rhythms are biological that oscillate with a period of approximately 24 hours. That is, a circadian rhythm is an internal daily biological clock. Blood pressureappears to follow such a rhythm. For a certain individual the average resting blood pressure varies from a maximum of 100 mmHG at 12:00 pm (noon) to a minimum of80 mmHG at 12:00 am (midnight). Write a model that represents the blood pressure at time t measured in hours from 12:00 pm (noon)

Some of the highest tides in the world occur in the Bay of Fundy on the Atlantic Coast of Canada. At Hopewell Cape the water depth at low tide is about 2.0 m and at high tide it is about 12.0 m. The natural period of oscillation is a little more than 12 hours and on June 30, 2009, high tide occurred at 6:45 a.m. This helps explain the following model for the water depth D (in meters) as a function of time t (in hours after midnight) on that day: D(t) = 6 + 7 cos(0.503(t - 6.75)). How fast was the tide rising (or falling) at the following times? a. 6:00 a.m. b. 2:00 p.m.
A bacteria culture had a population of 13 million at 10:00 am and by 2:00 pm had grown to 21 million. Predict the population at 6:00 pm that same day.
Plot the given data on Log-Log graph paper with depth on the X-axis and discharge on the Y-axis.a) Identify and give the value of the point where your best fit curve intersects the Y-axis at X = 1.b) Calculate the slope of the curve using (Log Y2 - Log Y1)/(Log X2 - Log X1) and mark on the graph.c) Comment on the shape of the curve and whether or not a linear equation (Y = a +bX) will provide a reasonable fit to the data.

The mean life of a radioactive material is the reciprocal of its decay constant. Show that 95% of a radioactive material decays approximately in a time period of 3 times its mean life.
3. Radar guns measure the rate of distance change between the gun and the object it is measuring. For instance, a reading of "55 mph" means the object is moving away from the gun at a rate of 55 miles per hour, whereas a measurement of "-25 mph" would mean that the object is approaching the gun at a rate of 25 miles per hour. If the radar gun is moving (say, attached to a police car) then radar readouts are only immediately understandable if the gun and the object are moving along the same line. If a police officer is traveling 60 mph and gets a readout of 15 mph, he knows that the car ahead of him is moving away at a rate of 15 miles an hour, meaning the car is traveling 75 mph. (This straight-line principle is one reason officers park on the side of the highway and try to shoot straight back down the road. It gives the most accurate reading.) Suppose an officer is driving due north at 30 mph and sees a car moving due east, as shown in the picture below. Using his radar gun, he…
