An aluminum sphere is heated from 11°C to 580°C. If the volume of the sphere is 1.78 cm3 at 11°C, what is the increase in volume of the sphere at 580°C?

Write an essay in which you agree or disagree, in full or in part, with the idea that life would have been good for a Roman citizen living in Rome during the days of the Early Empire. Include accurate facts from "Living Conditions in Rome,"as well as what you know about the privileges of Roman citizenship. Use your sense of the world at that time to supplement and explain your personal feelings about life in the greatest city of the great Roman Empire.

Write four sentences that describe Montresor's act of revenge against Fortunato, using the active voice twice and the passive voice twice. With a partner, discuss which sentences are more effective and why.

Professor Grant Alexander wanted to find a linear model that relates the number of hours a student plays video games each week, h, to the cumulative grade-point average, G, of the student. He obtained a random sample of 10 full-time students at his college and asked each student to disclose the number of hours spent playing video games and the student’s cumulative grade-point average.

$$\begin{matrix} \text{Hours of} & \text{Grade-point}\\ \text{Video Games} & \text{Average, $G$}\\ \text{per Week, $h$} & \text{ }\\ \hline \text{0} & \text{3.49}\\ \text{0} & \text{3.05}\\ \text{2} & \text{3.24}\\ \text{3} & \text{2.82}\\ \text{3} & \text{3.19}\\ \text{5} & \text{2.78}\\ \text{8} & \text{2.31}\\ \text{8} & \text{2.54}\\ \text{10} & \text{2.03}\\ \text{12} & \text{2.51}\\ \end{matrix}$$

How many hours of video game playing do you think a student plays whose grade-point average is 2.40?

A triangle has vertices $\left(x_{1}, y_{1}\right),\left(x_{2}, y_{2}\right),$ and $\left(x_{3}, y_{3}\right).$ The area of the triangle is given by the absolute value of D, where

$$D=\frac{1}{2}\left|\begin{array}{lll}{x_{1}} & {x_{2}} & {x_{3}} \\ {y_{1}} & {y_{2}} & {y_{3}} \\ {1} & {1} & {1}\end{array}\right|.$$

Use this formula to find the area of a triangle with vertices (2, 3), (5, 2), and (6, 5).

For each of the following quadratic equations, find the discriminant $\Delta$ and hence draw its sign diagram. Find all values of k for which the equation has: (i) two distinct real roots (ii) two real roots (iii) a repeated root (iv) no real roots. $k x^{2}-2 x+k=0$

A bar of an unknown metal has a length of 0.975 m at 45°C and a length of 0.972 m at 23°C. What is its coefficient of linear expansion?

There is 100.0 mL of water in an 800.0-mL soft-glass beaker at $15.0^{\circ} \mathrm{C}$. How much will the water level have dropped or risen when the bottle and water are heated to $50.0^{\circ} \mathrm{C}$?

A scuba diver swimming at a depth of 5.0 m under water exhales a $4.2 \times 10^{-6} \mathrm{m}^{3}$ bubble of air. What is the volume of that bubble just before it reaches the surface of the water?

A very long wire carries a current $I_{1}$ upward and this current is decreasing with time. Nearby is a rectangular loop of wire lying in the plane of the long wire, and containing a resistor R; the resistance of the rest of the loop is negligible compared to R. The loop has a width w and height h, and is located a distance d to the right of the long wire. Does the current $I_{2}$ in the loop run clockwise or counterclockwise? Explain, using a diagram.

Graph the data in the following table using a divided bar graph.

$$\begin{matrix} \text{} & \text{State Gasoline Prices, April 2017} & \text{}\\ \text{State} & \text{Price Before Tax (\$ per gallon)} & \text{Tax}\\ \text{California } & \text{2.41} & \text{.57}\\ \text{Hawaii} & \text{2.42} & \text{.63}\\ \text{Michigan } & \text{1.90} & \text{.59}\\ \text{New York} & \text{1.83} & \text{.62}\\ \text{Texas } & \text{1.80} & \text{.38}\\ \end{matrix}$$
