A common assumption in modeling drug assimilation is that the blood volume in a person is a single compartment that behaves like a stirred tank. Suppose the blood volume is a four-liter tank that initially has a zero concentration of a particular drug. At time $t = 0$ , an intravenous line is inserted into a vein (into the tank) that carries a drug solution with a concentration of 500 mg/L. The inflow rate is 0.06 L/min. Assume the drug is quickly mixed thoroughly in the blood and that the volume of blood remains constant. a. Write an initial value problem that models the mass of the drug in the blood, for $t \geq 0$ . Solve the initial value problem, and graph both the mass of the drug and the concentration of the drug. c. What is the steady-state mass of the drug in the blood? d. After how many minutes does the drug mass reach 90% of its steady-state level?

Indicate whether the expression defines a polynomial function. $g (x) = - 4 x^{5} - 3 x^{2} + x - 2$ polynomial or not a polynomial If it is a polynomial function, identify the following. (If it is not a polynomial function, enter DNE for all three answers.) (a) Identify the leading coefficient. (b) Identify the constant term. (c) State the degree.

a) Use base b = 10, precision k = 4, idealized, chopping floating-point arithmetic to show that fl(g(1.015)) is inaccurate, where $g (x) = \frac{x^{\frac{1}{4}} - 1}{x - 1}$ b) Derive the second order (n = 2) quadratic Taylor polynomial approximation for $f (x) = x^{\frac{1}{4}}$ expanded about a = 1, and use it to get an accurate approximation to g(x) in part (a). c) Verify that your approximation in (b) is more accurate.

An option on land in Alaska was bought by an oil company. The following prior probabilities were assigned by preliminary geologic studies.
$P P (high-quality oil) = .50 P (medium-quality oil) = .20 P (no oil) = .30$
a. What is the probability of finding oil?
b. After 200 feet of drilling on the first well, a soil test is taken. The probabilities of finding the particular type of soil identified by the test follow.
$P (soil | high-quality oil) = .20 P (soil | medium-quality oil) = .80 P (soil | no oil) = .20$
How should the firm interpret the soil test? What are the revised probabilities, and what is the new probability of finding oil?
