It is time to clean the water tank. The process requires draining a 75-gallon tank. To siphon the water out
of the tank, he uses a hose that drains 6.5-gallons out of the tank in 15 minutes. How long will it take the
tank to be drained of water?
a.
Make a table comparing the elapsed time with the amount of water left in the tank over time.
NOTE: The x-axis is usually used to represent time.
b.
Write an equation describing the relationship between the elapsed time and the amount of water
remaining in the tank.
C. Draw a graph. Discuss the meaning of the x-intercept and the y-intercept in this situation.
d. Why might the information from the table in part (a) and the graph in part (b) be important to
know?
Que: Coroners estimate time of death using the rule of thumb that a body cools about 2
degrees F during the first hour after death and about 1 degree F for each additional hour.
Assuming an air temperature of 66 degrees F and a living body temperature of 98.6 degrees F,
the temperature T(t) in degrees F of a body at a time t hours since death is given by
T(t) = 66 + 32.6e .
%3D
1. For what value of k will the body cool by 2 degrees F in the first hour?
k =
2. Using the value of k found above, after how many hours will the temperature of the body be
decreasing at a rate of 1 degree F per hour?
after
hours
3. Using the value of k found above, show by calculating both values that, 24 hours after death,
the coroner's rule of thumb gives approximately the same temperature as the formula.
T(24) =
degrees F
rule of thumb gives T =
degrees F
