Generate two graphs and on each draw a line through the points (0,3) and \((4,6),\) choosing \(x\) and \(y\) scales such that: a. The first line appears to have a slope of almost zero. b. The second line appears to have a very large positive slope.
The electrical resistance \(R\) (in ohms) of a wire is directly proportional to its length \(l\) (in feet). a. If 250 feet of wire has a resistance of 1.2 ohms, find the resistance for \(150 \mathrm{ft}\) of wire. b. Interpret the coefficient of \(l\) in this context.
Which lines are parallel to each other? Which lines are perpendicular to each other? a. \(y=\frac{1}{3} x+2\) c. \(y=-2 x+10\) e. \(2 y+4 x=-12\) b. \(y=3 x-4\) d. \(y=-3 x-2\) f. \(y-3 x=7\)
The following table shows U.S. first-class stamp prices (per ounce) over time. $$ \begin{array}{lc} \hline \text { Year } & \text { Price for First-Class Stamp } \\ \hline 2001 & 34 \text { cents } \\ 2002 & 37 \text { cents } \\ 2006 & 39 \text { cents } \\ \hline \end{array} $$ a. Construct a step function describing stamp prices for \(2001-2006 .\) b. Graph the function. Be sure to specify whether each of the endpoints is included or excluded. c. In 2007 the price of a first-class stamp was raised to 41 cents. How would the function domain and the graph change?
Assume that \(R\) is measured in dollars, \(S\) in ounces. \(T\) in dollars per ounce, and \(V\) in ounces per dollar. Write a product of two of these terms whose resulting units will be: a. Dollars b. Ounces
