More than 600,000 immigrants passed through Ellis Island in 1912, the year residents of the Lower East Side wrote this letter to President Taft criticizing the disparaging remarks of the New York commissioner of immigration. Unlike earlier waves of immigration, increasing numbers hailed from Southern and Eastern Europe, including Jews and other groups that many Americans feared as radical and inassimilable. This anxiety led to a study published in $1911$ by the Dillingham Commission recommending immigration restriction, which would later be enacted in the early $1920$s. Here, a citizens' committee of the Lower East Side responds by affirming their identity as Americans.

Examine the role of ethnic identity in shaping both the Commission of Immigration's characterization of Lower East Side residents and their response. To what extent did their ethnicity define them in their own minds?

Which groups in source 5 were over-and underrepresented in the Klan? The same historian found that at least 34 percent of local Klan members were German American. Review the Thinking Like a Historian feature in Chapter 20, pages 640-641. Why might Germans have been especially likely to join the Klan in this period?

Axl and Aneeza pay for and share memory storage at a remote Internet site. Their plan allows them upload 250 terabytes (TB) or less of data each month. Let x represent the number of terabytes Axl uploads in a month, and let y represent the number of terabytes Aneeza uploads in a month. Look at the data for four months below. Determine if Axl and Aneeza stayed within the limits of their monthly plan.

$$\begin{matrix} \text{Axl's} & \text{Aneeza's} & \text{Within Plan?}\\ \text{Uploads (x)} & \text{Uploads (y)} & \text{(Yes/No)}\\ \text{50 TB} & \text{120 TB} & \text{ }\\ \text{135 TB} & \text{100 TB} & \text{ }\\ \text{100 TB} & \text{150 TB} & \text{ }\\ \text{162 TB} & \text{128 TB} & \text{ }\\ \end{matrix}$$

Write an inequality that models the plan's restriction on uploading.

A 100 N force, directed at an angle theta above a horizontal floor, is applied to a 25.0 kg chair sitting on the floor. If theta = 0 degree, what are the horizontal component Fh of the applied force ?

Two harmonic water waves of equal amplitudes but different frequencies, wave numbers, and speeds are traveling in the same direction. In addition, they are superposed on each other. The total displacement of the wave can be written as $y(x, t)=A\left[\cos \left(k_1 x-\omega_1 t\right)+\cos \left(k_2 x-\omega_2 t\right)\right]$, where $\omega_1 / k_1=v_1$ (the speed of the first wave) and $\omega_2 / k_2=v_2$ (the speed of the second wave). $(b)$ Let $A=1.00 \text{~cm}, \omega_1=1.00 \text{rad} / \text{s}, k_1=1.00 \text{~m}^{-1}$, $\omega_2=0.900 \text{rad} / \text{s}$, and $k_2=0.800 \text{~m}^{-1}$. Using a spreadsheet program or graphing calculator, make a plot of $y(x, t)$ versus $x$ at $t=0.00 \text{~s}$ for $0<x<5.00 \text{~m}$. "

According to a simple physiological model, an athletic adult male needs 20 Calories per day per pound of body weight to maintain his weight. If he consumes more or fewer Calories than those required to maintain his weight, his weight changes at a rate proportional to the difference between the number of Calories consumed and the number needed to maintain his current weight; the constant of proportionality is 1/3500 pounds per Calorie. Suppose that a particular person has a constant caloric intake of I Calories per day. Let W(t) be the person's weight in pounds at time t (measured in days). (a) What differential equation has solution W(t)? (b) Find the equilibrium solution of the differential equation. Based on the context, do you expect the equilibrium to be stable or unstable? (c) Solve this differential equation. (d) Graph W(t) if the person starts out weighing 160 pounds and consumes 3000 Calories a day.
