Problem: Write an article based on this summary: Adjoin the identity matrix to the original matrix. Perform linear row reduction operations. Continue until you form the identity matrix. Write out the inverse matrix.

Answer: Write out the original matrix M, draw a vertical line to the right of it, and then write the identity matrix to the right of that. You should now have what appears to be a matrix with three rows of six columns each. Recall that the identity matrix is a special matrix with 1s in each position of the main diagonal from upper left to lower right, and 0s in all other positions. For a review of the identity matrix and its properties, see Understand the Basics of Matrices. Your objective is to create the identity matrix on the left side of this newly augmented matrix. As you perform row reduction steps on the left, you must consistently perform the same operations on the right, which began as your identity matrix. Remember that row reductions are performed as a combination of scalar multiplication and row addition or subtraction, in order to isolate individual terms of the matrix. For a more complete review, see Row-Reduce Matrices. Keep repeating linear row reduction operations until the left side of your augmented matrix displays the identity matrix (diagonal of 1s, with other terms 0). When you have reached this point, the right side of your vertical divider will be the inverse of your original matrix. Copy the elements now appearing on the right side of the vertical divider as the inverse matrix.

Problem: Write an article based on this summary: Discuss long-term and quick-relief medications with the pediatrician. Have your child take daily control medications as directed. Attach a spacer to their inhaler so it's easier to use. Have your child use a nebulizer if they can't use an inhaler. Record your child's normal breathing with a peak flow meter.

Answer: Your child's pediatrician will likely prescribe a daily control medication, such as a inhaled long-term bronchodilator. For flare-ups, the pediatrician will also prescribe a short-term medication, such as albuterol. The pediatrician might also prescribe inhaled or oral corticosteroids and medications for allergies. Long-term control medications are taken daily and help prevent asthma flare-ups. Quick-relief medications are used to open the airways during flare-ups. When asthma is well-controlled, your child shouldn't need quick-relief medication more than once or twice a week. Long-term asthma medications are available in pill, liquid, and inhaled forms. Help your child take their asthma control medicine every day, even if they don't have symptoms. Ask the pediatrician to explain how much medicine to take, when to take it, and how to use the inhaler or nebulizer. Make sure that you read all of the instructions and enclosed pamphlets that come with your child's medication. Your child's treatment plan should thoroughly explain how to administer their medication. Ask your pediatrician or pharmacist if you're in doubt about something. Children often have trouble using inhalers properly, so ask for a spacer that fits your child's inhaler. Shake the inhaler, spray 1 to 2 test puffs into the air, attach it to the spacer's opening, then have your child tightly close their lips around the spacer's mouthpiece. Press the inhaler to spray 1 puff (or as many as directed), and have your child breathe in slowly and deeply. After they inhale the medication, they can take the spacer out of their mouth. Have them hold their breath for 10 seconds. Then, they should pucker their lips and slowly exhale through their mouth. A spacer collects the medicine, so there's no need to carefully time breaths with the inhaler sprays. You'll likely need a prescription for the right spacer from your pediatrician or pharmacist. The pediatrician might prescribe a nebulizer for young children and for some medications. Connect the hose to the machine, and fill the medicine cup with the proper dose. Turn the machine on, and have your child breathe in slowly and deeply through the mouthpiece for 10 to 15 minutes. A nebulizer turns liquid medicine into a mist. Specific instructions vary, so use your product as directed. Have your child inhale deeply and tightly close their lips around their peak flow meter's mouthpiece. Then, they should blow out as hard and quickly as they can.Image:Treat Asthma in Pediatric Patients Step 13.jpg Have them repeat the steps 3 times, then record the highest score. Their personal best score when they're not experiencing symptoms will provide a comparison during flare-ups.

Problem: Write an article based on this summary: Review your PowerPoint. Click the Slide Show tab. Click From Beginning. Page through the slide show. Make any necessary changes before proceeding. Save your PowerPoint.

Answer: Once you've finished adding the bulk of your PowerPoint presentation's content, skim through it slide-by-slide to ensure that you haven't left anything out. This tab is at the top of the window. Doing so opens the Slide Show toolbar. It's in the far-left corner of the toolbar. Your PowerPoint presentation will open in slide show view. You can use the left and right arrow keys to move back and forward through the presentation. If you need to exit the presentation, press Esc. When you're done scrolling through the presentation, add any details that you forgot, delete any content that you want to remove, and so on. This will save your presentation as a file which can be opened on any Windows or Mac computer that has PowerPoint installed: Windows - Click File, click Save, double-click This PC, select a save location, enter a name for your presentation, and click Save. Mac - Click File, click Save As..., enter the presentation's name in the "Save As" field, select a save location by clicking the "Where" box and clicking a folder, and click Save.

Problem: Write an article based on this summary: Comb it out with dry shampoo. Cover the worst areas with your hairstyle. Wear light colors. Wear a hat or scarf. Carry a lint roller.

Answer:
Dry shampoo can clean and moisturize your scalp when applied before you go out. It can be found in drugstores or online and comes in spray and powder form. To apply, spray your hair a few times or sprinkle a little on top of your scalp. Comb in the spray or powder, which will help comb out any dandruff flakes. Rinse your comb after each stroke. Talcum powder can be used instead, but it can make dark or black hair look grey, white, or dotted. Find the region of your scalp with the most dandruff, and comb your hair so it covers this area. Hairstyling products may help you achieve this task, but fluffing up your hair into a tousled look can work as a quick improvement. Covering up the dandruff is not actually treating anything, and you should keep in mind that this is only a quick visual fix. The best way to get rid of dandruff is to actually use treatment methods that will affect the underlying causes. Select a shirt, dress, or other top with a white, grey, or metallic appearance. This will make white or yellow dandruff flakes much less noticeable. Textured or patterned clothing may help hide the dandruff as well. Any cap, hat, or scarf can be used to hide the dandruff on your scalp. As long as it's on, it will also minimize the number of dandruff flakes that fall onto your clothing. Plus, people will not be able to see any flakes that are stuck to your hair. Pocket a mini-lint roller before you head outside. Any time you see dandruff flakes on your clothing, make a trip to the bathroom and use the lint roller to pick them up off the fabric. If you can't get your back, have a friend or loved one help you.
