INPUT ARTICLE: Article: Finding the NPVs for multiple investment opportunities allows you to easily compare your investments to determine which are more valuable than others. In general, the investment with the highest NPV is the most valuable because its eventual payout is worth the most in present dollars. Because of this, you'll usually want to pursue the investments with the highest NPVs first (assuming you don't have enough resources to pursue every investment with a positive NPV). For instance, let's say that we have three investment opportunities. One has an NPV of $150, one has an NPV of $45, and one has an NPV of -$10. In this situation, we'd pursue the $150 investment first because it has the greatest NPV. If we have enough resources, we'd pursue the $45 investment second because it's less valuable. We wouldn't pursue the -$10 investment at all because, with a negative NPV, it will make you less money than investing in an alternative with a similar level of risk. Using a slightly modified form of the standard NPV formula, it's possible to quickly determine how much a present sum of money will be worth in the future (or how much a future sum of money is worth in the present). Simply use the formula PV = FV / (1+i)t, where i is your discount rate, t the number of time periods being analyzed, FV is the future money value, and PV is the present value. If you know i, t, and either FV or PV, it's relatively simple to solve for the final variable. For instance, let's say we want to know how much $1,000 will be worth in five years. If we know that, at bare minimum, we can get a return rate of 2% on this money, we'll use 0.02 for i, 5 for t, and 1,000 for PV and solve for FV as follows: 1,000 = FV / (1+0.02)5 1,000 = FV / (1.02)5 1,000 = FV / 1.104 1,000 1.104 = FV = $1,104. The accuracy of any NPV calculation basically depends on the accuracy of the values you use for your discount rate and your future cash inflows. If your discount rate is close to the actual return rate you can get on your money for an alternative investment of similar risk and your future cash inflows are close to the amounts of money you'll actually make from your investment, your NPV calculation will be right on the money.

SUMMARY: Compare investment opportunities by their NPV. Use PV = FV / (1+i)t to find present and future values. Research valuation methods for more accurate NPVs.

In one sentence, describe what the following article is about: You can also use paper towel tubes, but you will need to cut them in half. Use enough tape so that there are no holes. If there are any holes, the chalk mixture will leak. Cut the wax paper into 6 inch by 6 inch (15.25 centimeters by 15.25 centimeters) squares. Roll the wax paper into a tube and slip it inside each toilet paper roll. Gently spread the wax paper out until it is the same size as the toilet paper roll. The top of the wax paper should stick out of the top of the tube. The wax paper will protect the cardboard from the chalk mixture.
Summary: Gather three to six toilet paper rolls. Cover one end of each tube with duct tape. Line the tubes with wax paper.

Death is always close at hand in Minecraft. Read about how to die in the section below. But if you don't want to lose all your items, read this section first. Make a chest out of eight wooden planks. Place the chest on the ground, then move all valuable items from your inventory into the chest. In single player, place the chest somewhere obvious, such as on the top of a hill. In multiplayer, hide the chest underground to hide it from other players. Mark the land above it with a torch so you know where to dig later. If you have OP rights (Cheats), you can also use the command /gamerule keepInventory true to protect your inventory. These coordinates will tell you exactly where you are in the world. Check them while standing next to your chest: In Minecraft for Windows or Mac, press F3. (If that doesn't work, press Fn+F3.) In Minecraft for Xbox or PlayStation, make a map, equip it and use it. There is a way to find coordinates in Minecraft Pocket Edition. Go into game settings and scroll down until you find the 'Show Coordinates' button. Slide the button across and there should be 3 sets of numbers at the top of your screen when you return back. Write down the X, Y, and Z values that appear as text at the top of the screen, or on the map. Use a real piece of paper, not just the chat box. Kill yourself any way you like. There are many methods listed in the next section below. When you respawn, you'll be back at the last bed you slept in, or your original spawn point. Use the method described above to display your coordinates. Write down these as well, so you don't get lost again. With the coordinates open, walk around and watch the X, Y, and Z values change. Find the direction that causes these values to approach the coordinates you wrote down earlier. When you reach them, look around for your chest. Pick up your items, and walk back to your spawn point using the same method. X and Z are the North/South and East/West coordinates. Get these right first. The Y value tells you how far you are above or below sea level. You can usually ignore this unless you died underground or on a steep mountain slope. If you have commands on, you could type the command "/gamerule keepInventory true" into the chat. This makes it so that your items are with you, even after you die.

One-sentence summary -- Choose your death. Store your items in a chest. Check your coordinates. Write down your coordinates. Kill yourself. Check your coordinates. Use the coordinates to find your item chest. Retain your items.

INPUT ARTICLE: Article: 7-Zip is a free utility that can quickly decompress TGZ files. It's a good idea to download a .exe file of the most recent version (that isn't a beta). Be sure to click the link next to the right version of Windows (32-bit or 64-bit). This opens the 7-Zip installer. 7-Zip will now install on your computer. Once the installation is complete, move to the next step. A menu will appear. An additional menu will expand. This tells 7-Zip to create a new folder (named after the .tgz file) in the current directory. The contents of the file will now extract to the selected location. If the only file that appears ends in .TAR, double-click it to extract the remaining files. To select a different location, choose Extract Files instead, then choose a location.

SUMMARY:
Go to http://www.7-zip.org/download.html in a web browser. Click Download next to the correct version. Double-click the file you downloaded. Click Install. Right-click the .tgz file. Navigate to the 7-Zip menu. Click Extract to (Folder Name).
