Steam enters a nozzle at 800 kPa and $280^\circ C$ at negligible velocity and discharges at a pressure of 525 kPa. Assuming isentropic expansion of the steam in the nozzle, what is the exit velocity and what is the cross-sectional area at the nozzle exit for a flow rate of $0.75 \mathrm{kg} \cdot \mathrm{s}^{-1} ?$

(a) A point charge q is located at the center of a cube of edge d. What is the value of $\int \mathbf{E} \cdot d \mathbf{a}$ over one face of the cube? (b) The charge q is moved to one corner of the cube. Now what is the value of the flux of E through each of the faces of the cube? (To make things well defined, treat the charge like a tiny sphere.)

Why graphing can be an important tool for analyzing data.

When the catenary y=a cosh (x/a) is revolved about the x-axis, it sweeps out a surface of revolution called a catenoid. Find the area of the surface generated when y=cosh x on [-ln 2, ln 2] is rotated around the x-axis.

Sketch the graph of $y=\frac{9}{2 x+3}$ for positive values of x. The part of the curve between x = 0 and x = 3 is rotated through $2 \pi$ radians about the x-axis. Calculate the volume of the solid of revolution formed.

Estimate the atmospheric pressure inside Hurricane Rita. The wind speed was $290 \mathrm{~km} / \mathrm{h}$.

Calculate your apparent weight at the top and bottom of a Ferris wheel, given that the radius of the wheel is $7.2 \mathrm{~m}$, it completes one revolution every $28 \mathrm{~s}$, and your mass is $55 \mathrm{~kg}$.

A CD with diameter 12 cm spins in a CD player. Calculate how much farther a point on the outside edge of the CD travels in one revolution than a point 1 cm closer to the center of the CD.

Determine the mean and standard deviation of the variable X in each of the following binomial distributions:

a. n = 4 and $\pi$ = 0.10

b. n = 4 and $\pi$ = 0.40

c. n = 5 and $\pi$ = 0.80

d. n = 3 and $\pi$ = 0.50

Express $h(x)=(2 x+3)^7$ as a composition of two functions $f$ and $g$ so that $h(x)=(f \circ g)(x)$.

The following table contains the number of successes and failures for three categories of a variable.

$$\begin{matrix} \text{ } & \text{Category 1} & \text{Category 2} & \text{Category 3}\\ \text{Success} & \text{204} & \text{199} & \text{214}\\ \text{Failure} & \text{96} & \text{121} & \text{98}\\ \end{matrix}$$

Test whether the proportions are equal for each category at the $\alpha$=0.01 level of significance.
