Have you ever participated in a bicycle race? How fast did you pedal?

Hopefully, you $\overset{\text{(1)}}{{\underline{\text{weren't clocked at a speed of 190 mph}}}}$. In professional motorcycle road racing, however, $\overset{\text{(2)}}{{\underline{\text{riders}}}}$ actually reach this astonishing speed.

$\overset{\text{(3)}}{{\underline{\text{Helmets and leather body suits}}}}$ are worn for this sport. $\overset{\text{(4)}}{{\underline{\text{Regular motorcycles are purchased and then modified by mechanics}}}}$. $\overset{\text{(5)}}{{\underline{\text{From these modifications emerge lighter and faster bikes}}}}$. These special bikes are also $\overset{\text{(6)}}{{\underline{\text{durable}}}}$. $\overset{\text{(7)}}{{\underline{\text{They have to be to endure the 60-mile course}}}}$!

Racers use a $\overset{\text{(8)}}{{\underline{\text{technique}}}}$ called drafting to pass their opponents. As the lead racer pushes against the air, the next rider gets as close as possible. With less wind resistance between the two bikes, the racer on the trailing bike flies right by. The slightest mistake could be a $\overset{\text{(9)}}{{\underline{\text{disaster}}}}$. To avoid accidents, riders attend a special $\overset{\text{(10)}}{{\underline{\text{school}}}}$.

In at least ten places, the immigrants above report on wages-daily, weekly, or monthly. For comparison, make a rough conversion of all of these to weekly wages and list them. What do you conclude about compensation for professional, skilled, and unskilled work?

From your notes, choose two or three aspects of the character you'll want to focus on. Then, figure out what your main points will be, and express each point as a general statement. This statement will serve as the topic sentence of a paragraph. Jot down the evidence you'll use to support each general statement. You'll end up with a rough outline that shows your main points and supporting evidence.

If you haven't already done so, draft a thesis statement, a one- or two-sentence summary of your main points about your character.

A tension force of 175 N inclined at $20.0^{\circ}$ above the horizontal is used to pull a 40.0-kg packing crate a distance of 6.00 m on a rough surface. If the crate moves at a constant speed, find the coefficient of kinetic friction between the crate and surface.

A rough rule of thumb for determining the distance between you and a lightning strike is to start counting the seconds that elapse (“one-Mississippi, two-Mississippi, . . .”) until you hear the thunder (sound emitted by the lightning as it rapidly heats the air around Assuming the speed of sound is about 750 mi/h,

$(b)$ Estimate the uncertainty in the distance to the strike in Part (a). Be sure to explain your assumptions and reasoning. Hint: The speed of sound depends on the air temperature, and your counting is far from exact!

Show, Don't Tell General descriptions won't help your reader see your subject. Use some of the concrete, sensory details you collected in your Writer's Notebook. Express those details with precise and vivid nouns, verbs, and modifiers, as in the following passage:

Mrs. Donovan sank to her knees and for a few moments she gently stroked the rough hair of the head and chest. "He's dead, isn't he?" she whispered at last. -James Herriot, "Haven't I Made a Difference!'' (page 408)

Make a rough sketch of the curve $y=x^{n}$ (n an integer) for the following five cases: (i) n=0 (ii) n>0, n odd (iii) n>0, n even (iv) n<0, n odd (v) n<0, n even. Then use these sketches to find the following limits. $\lim _{x \rightarrow 0^{-}} x^{n}$

We met the Tour de France data set in Chapter 1 (in Just Checking). One hundred years ago, the fastest rider finished the course at an average speed of about $25.3 \mathrm{kph}$ (around $15.8 \mathrm{mph}$ ). By the $21 \mathrm{st}$ century, winning riders were averaging over $40 \mathrm{kph}$ (nearly $25 \mathrm{mph}$ ).

a) Make a scatterplot of Avg Speed against Year. Describe the relationship of Avg Speed by Year, being careful to point out any unusual features in the plot.

b) Find the regression equation of Avg Speed on Year.

c) Are the conditions for regression met? Comment.

The boundary layer for the wind blowing over rough terrain can be approximated by the equation $u / U=[y /(y+0.02)]$. where $y$ is in meters. If the free-stream velocity of the wind is $10 \mathrm{~m} / \mathrm{s}$, find the velocity at $y=0.2 \mathrm{~m}$ and at $y=0.4 \mathrm{~m}$ from the ground.

A popular amusement park ride whisks riders to the top of a $250$-foot tower and drops them at speeds exceeding $50$ miles per hour. A function for the path of a rider is $h=-16 t^2+ 250$ , where $h$ is the height and $t$ is the time in seconds.

The ride stops the descent of the rider $40$ feet above the ground. Write an equation that models the drop of the rider.

In Exercise given below, draw by hand a rough sketch of the graph of each function. (You may wish to support your answer with a calculator graph.)

$P(x)=x^4+3 x^3-3 x^2-11 x-6$

$$=(x+3)(x+1)^2(x-2)$$

You put some ice cubes in a glass, fill the glass with cold water, and then let the glass sit on a table. Describe how the temperature of the water changes as time passes. Then sketch a rough graph of the temperature of the water as a function of the elapsed time.
