OXYGEN CONTENT OF A POND The oxygen content t days after organic waste has been dumped into a pond is given by
percent of its normal level.
- a. Show that f(0) = 100 and f(10) = 75.
- b. Use the Intermediate Value Theorem to conclude that the oxygen content of the pond must have been at a level of 80% at some time.
- c. At what time(s) is the oxygen content at the 80% level?

- bThe average rate of change of the linear function f(x)=3x+5 between any two points is ________.arrow_forwardFind the average rate of change of f(x)=x2+2x8 on the interval [5,a] in simplest forms in terms ofa.arrow_forwardCortisone Concentration A mathematical model for the concentration of administered cortisone in humans over a 24 hour period uses the function C=DaV(ab)(ebteat) Where C is the concentration, D is the dose given at time t=0, V is the volume of distribution volume divided by bioavailability, a is the absorption rate, b is the elimination rate, and t is the time in hours. Source: Journal of Pharmacokinetics and Bio pharmaceutics. a. What is the value of C at t=0? Explain why this makes sense. b. What happens to the concentration as a large amount of time passes? Explain why this makes sense. c. The researchers used the values D=500micrograms,a=8.5,b=0.09 andV=3700liters. Use these values and a graphing calculator to estimate when the concentration is greatest.arrow_forward
