Suppose that you have the following declaration:

stackType<double> stack(50);
double num;

and the input is 25 64 -3 6.25 36 -4.5 86 14 -12 9 Write a C++ code that processes this input as follows: If the number is nonnegative, it pushes the square root of the number onto the stack; otherwise it pushes the square of the number onto the stack. After processing these numbers write a C++ code that outputs the elements of the stack.

Frightproof Commuter Airlines is trying to add a new flight to its current schedule from Metro to Hicksville. This route has the following prices and costs:

How many passengers per flight must Frightproof have to earn$1,050 per flight after taxes?

Sphalerite is a zinc sulfide (ZnS) mineral and an important commercial source of zinc metal. The first step in the processing of the ore consists of heating the sulfide with oxygen to give zinc oxide, $\mathrm{ZnO}$, and sulfur dioxide, $\mathrm{SO}_2$. How many kilograms of oxygen gas combine with $5.00 \times 10^3 \mathrm{~g}$ of zinc sulfide in this reaction? (You must first write the balanced chemical equation.)

Lutetium is a rare-earth element that can be used to speed up the chemical reactions involved in petroleum processing. It has two naturally occurring isotopes.

$$\begin{matrix} \text{Isotope} & \text{Form of Decay} & \text{Percent Abundance}\\ \ {^{175} _{71} Lu} & \text{none} & \text{97,41}\\ \ {^{176} _{71} Lu} & \text{beta} & \text{2,59}\\ \end{matrix}$$

Compare the number of protons and neutrons in each of these isotopes.

A manufacturer of corrugated metal roofing wants to produce panels that are 28 in. wide and 2 in. thick by processing flat sheets of metal as shown in the figure. The profile of the roofing takes the shape of a sine wave. Verify that the sine curve has equation $y=\sin (\pi x / 7)$ and find the width $w$ of a flat metal sheet that is needed to make a 28-inch panel. (Use your calculator to evaluate the integral correct to four significant digits.)

Your firm is contemplating the purchase of a new $425,000 computer-based order entry system. The system will be depreciated straight-line to zero over its five-year life. It will be worth$30,000 at the end of that time. You will save $130,000 before taxes per year in order processing costs, and you will be able to decrease working capital by$60,000 (this is a one-time reduction). If the tax rate is 35%, what is the IRR for this project?

A plane flies 3000 miles from San Francisco to Boston in 5 hours, with a tailwind all the way. The return trip on the same route, now with a headwind, takes 6 hours. Assuming both remain constant, find the speed of the plane and the speed of the wind. [Hint: If x is the plane's speed and y the wind speed (in miles per hour ), then the plane travels to Boston at x + y miles per hour because the plane and the wind go in the same direction; on the return trip, the plane travels at x - y miles per hour. (Why?)]

You’ve just completed a pilot run of 10 units of a major product and found the processing time for each unit was as follows. How much time would it take to make the 1,000th unit?

Your firm is contemplating the purchase of a new $485,000 computer-based order entry system. The system will be depreciated straight-line to zero over its five-year life. It will be worth$35,000 at the end of that time. You will save $140,000 before taxes per year in order processing costs, and you will be able to reduce working capital by$60,000 (this is a one-time reduction). If the tax rate is 24 percent, what is the IRR for this project?

Three astronauts, propelled by jet backpacks, push and guide a 120 kg asteroid toward a processing dock, exerting the forces with $F_1=32 \mathrm{~N},\theta_1=30^{\circ}$ from the positive $x$ axis in the first quadrant, $F_2=55 \mathrm{N}$ along the positive $x$ axis and ,$F_3=41 \mathrm{~N}, \theta_3=60^{\circ}$ from the positive $x$ axis in the fourth quadrant. What is the asteroid's acceleration direction relative to the positive direction of the $x$ axis?

Voeller Corporation produces ketchup. Voeller uses a process costing system to record costs. On October 1, Voeller had 18,000 bottles of ketchup in the Processing Department. The bottles were 100% complete as to direct materials and 30% complete as to conversion costs. The following data were gathered on October 31:

$$\begin{array}{lr} \text { Units started this period } & 620,000 \\ \text { Units completed this period } & 618,000 \\ \text { Units in ending work in process (100\% complete as to direct } \\ \quad \text { materials and } 60 \% \text { complete as to conversion costs) } & 20,000 \end{array}$$

Partially completed forms and a blank general journal are provided in the Working Papers.

Instructions:

1. Calculate equivalent units of production for the Processing Department for October.

2. Record the following transactions:

3. Using the cost information in Instruction 2c, assume that 560,000 bottles of ketchup were transferred to finished goods. If Voeller uses 20% as its percentage of markup, calculate the following per bottle:

a. Cost

b. Dollar amount of markup

c. Selling price

d. Profit margin

4. Voeller is in the process of developing a Cajun specialty sauce. The company believes that the selling price cannot exceed$3.00, and it requires a profit of 20% per unit. What is the target cost for the specialty sauce?
