A romance usually includes these motifs: adventure, quests, wicked adversaries, even magic. Describe the typical elements of a romance that you find in this tale. Are any of these elements found in TV shows and movies today? Explain.

John Steinbeck, who was captivated by Malory's tales as a boy, once compared the Arthurian legends to the American western movie. Take notes in the form of a chart, comparing and contrasting these two kinds of stories. Then, tell Which you prefer and Why.

You are Sir Launcelot, reporting to King Arthur about your adventures. Using the first person, briefly summarize the main events that befell you on your journey.

Write C if the italicized word is used correctly. Write I if the word is used incorrectly.

Two TV sets, three CD players, and a radio were all blaring away at once. The cacophony was unbearable.

The table below shows the IQ of ten students and the number of hours of TV each watches per week.

(a) Make a scatter plot of the data.

(b) By eye, make a rough estimate of the correlation coefficient.

(c) Use a calculator or computer to find the least squares regression line and the correlation coefficient. Your values should be correct to four decimal places.

A soap bubble with walls $418 \mathrm{~nm}$ thick floats in air. If this bubble is illuminated perpendicularly with sunlight, what wavelength (and color) will be absent in the reflected light? Assume that the index of refraction of the soap film is $1.33$.

In this exercise, change numbers in ordinary notation to scientific notation or change numbers in scientific notation to ordinary notation. See Appendix $B$ for an explanation of symbols used.

The frequency of a certain TV signal is $2,000,000,000 \mathrm{~Hz}$.

A camera is equipped with a lens with a focal length of $30 \mathrm{~cm}$. When an object $2 \mathrm{~m}(200 \mathrm{~cm})$ away is being photographed, how far from the film should the lens be placed?

Some spy satellites carry cameras with lenses $30 \mathrm{~cm}$ in diameter and with a focal length of $2.4 \mathrm{~m}$. $(a)$ What is the angular resolution of the camera according to Rayleigh's criterion? Assume that the wavelength of light is $550 \mathrm{~nm}$. $(b)$ If such a satellite looks down on the Earth from a height of $150 \mathrm{~km}$, what is the distance between two points on the ground that the camera can barely resolve? $(c)$ The lens projects images of the two points on a film at the focal plane of the lens. What is the distance between the two images projected on the film?

A 12-ft-long, 1.5-kW electrical resistance wire is made of 0.1-in-diameter stainless steel $\left(k=8.7 \mathrm{Btu} / \mathrm{h} \cdot \mathrm{ft} \cdot^{\circ} \mathrm{F}\right).$ The resistance wire operates in an environment at $85^{\circ} \mathrm{F}.$ Determine the surface temperature of the wire if it is cooled by a fan blowing air at a velocity of 20 ft/s. For evaluations of the air properties, the film temperature has to be found iteratively. As an initial guess, assume the film temperature to be $200^{\circ} \mathrm{F}.$

The television show NBC Sunday Night Football broadcast a game between the Colts and Patriots and received a share of 22, meaning that among the TV sets in use, 22% were tuned to that game (based on data from Nielsen Media Research). An advertiser wants to obtain a second opinion by conducting its own survey, and a pilot survey begins with 20 households having TV sets in use at the time of that same NBC Sunday Night Football broadcast.

a. Find the chance that none of the households are tuned to NBC Sunday Night Football.

A perfectly diffuse, or Lambertian, surface has the form of a square, $5\ \mathrm{cm}$ on a side. This object radiates a total power of $25\ \mathrm{W}$ into the forward directions that constitute half the total solid angle of $4\pi$. A camera with a $4\ \mathrm{cm}$ focal length lens and stopped down to $f/8$ is used to photograph the object when it is placed $1\ \mathrm{m}$ from the lens. (a) Determine the radiant exitance, radiant intensity, and radiance of the object. (b) Determine the radiant flux delivered to the film. (c) Determine the irradiance at the film.

Suppose you want to know whether the seventh-grade students at your school spend more time watching TV or using a computer. How might you choose a random sample from the population?

A local cable TV/Internet/phone provider charges new customers $99 for all three services, per month, for the first year under their “3 for 99” promotion. Joanne normally pays$54 for her monthly home phone service, $39 for Internet service, and$49 for cable television. Craig usually pays p dollars for phone service, i dollars for Internet service, and c dollars for cable TV service monthly. Represent his savings under the “3 for 99” plan algebraically, as a percent.
