The average annual price of single-family homes in Massachusetts between 1990 and 2002 is approximated by the function

$$P(t)= -0.183t^3 + 4.65t^2 - 17.3t + 200 \quad (0 \le t \le 12)$$

where $P(t)$ is measured in thousands of dollars and $t$ is measured in years, with $t=0$ corresponding to 1990. In what year was the average annual price of single-family homes in Massachusetts lowest? What was the approximate lowest average annual price? Hint: Use the quadratic formula

Use Poiseuille’s Law to calculate the rate of flow in a small human artery where we can take $\eta = 0.027, R = 0.008 \text{ cm}, l = 2 \text{ cm},$ and $P = 4000 \text{ dynes/cm}^2$.

Physiologists have observed that the flow of blood from an artery into a small capillary is given by the formula

$$F=k D^2 \sqrt{A-C} \quad\left(\mathrm{~cm}^3 / \mathrm{sec}\right)$$

where $D$ is the diameter of the capillary, $A$ is the pressure in the artery, $C$ is the pressure in the capillary, and $k$ is a positive constant.

a. By how much is the flow of blood $F$ changing with respect to pressure $C$ in the capillary if $A$ and $D$ are kept constant? Does the flow increase or decrease with increasing $C$ ?

b. What is the percentage rate of change of flow $F$ with respect to $A$ if $C$ and $D$ are kept constant?

Rita's family is moving from Grand Junction to Dallas. The van that is moving them averages 60 miles an hour. About how many hours does it take the family to reach their new home in Dallas?

A Pew Internet Poll asked cell phone owners about how they used their cell phones. One question asked whether or not during the past 30 days they had used their phone while in a store to call a friend or family member for advice about a purchase they were considering. The poll surveyed 1003 adults living in the United States by telephone. Of these, 462 responded that they had used their cell phone while in a store within the last 30 days to call a friend or family member for advice about a purchase they were considering. ${ }^3$ (a) What proportion of those surveyed reported that they used their cell phone while in a store within the last 30 days to call a friend or family member for advice about a purchase they were considering? (b) Discover the odds for the probability that you found in (a).

(Some questions have more than one correct answer. Select the best answer or answers from the choices given.) Arterial blood pressure increases in response to (a) increasing stroke volume, (b) increasing heart rate, (c) atherosclerosis, (d) rising blood volume, (e) all of these.

Calculate the rate (in cubic centimeters per second) at which blood flows through an artery of radius $0.1$ centimeter if the speed of the blood $r$ centimeters from the central axis is $8-800 r^2$ centimeters per second.

Jake was adopted as an infant and raised by his adoptive family. Jake has always been an extravert, but his adoptive parents are both quite introverted. A researcher discovers that Jake's twin brother, who was adopted by another family as an infant and whom Jake has never met, is also very extraverted. Which of the following concepts seems most related to Jake's extraversion? a. Extraversion as a heritable trait b. Extraversion as a learned trait c. Extraversion as a habitual trait d. Extraversion as a psychosexual trait
