Problem: Article: To calculate the normal force of an object at an angle, you need to use the formula: N = m * g * cos(x) For this equation, N refers to the normal force, m refers to the object's mass, g refers to the acceleration of gravity, and x refers to the angle of incline. Example: Find the normal force of a block with a mass of 4.2 kg, sitting on a ramp with an incline of 45 degrees. The cosign of an angle equals the sine of the complementary angle, or the adjacent side divided by the hypotenuse of the triangle formed by the incline. This value is often determined by a calculator, since the cosine of any angle is constant to that angle, but you can compute it manually, as well. Example: cos (45) = 0.71 The weight of an object equals the mass of the object multiplied by the acceleration of gravity. Note that the gravitational acceleration at the Earth's surface is a constant: g = 9.8 m/s2 Example: weight = m * g = 4.2 * 9.8 = 41.16 In order to find the normal force, you need to multiply the weight of the object by the cosine of the angle of incline. Example: N = m * g * cos(x) = 41.16 * 0.71 = 29.1 The previous step should complete the problem and give you your answer. Note that for an object sitting on an incline, the normal force should be less than the weight of the object. Example: The normal force is 29.1 N.
Summary: Use the right equation. Find the cosine of the angle. Find the object's weight. Multiply the two values together. Write your answer.

INPUT ARTICLE: Article: Many people with Down Syndrome are described as having flat, rounded, wide noses with small nasal bridges. The nasal bridge is the flat section of the nose between the eyes. This area can be described as being "pushed in." Those with Down Syndrome usually exhibit round eyes that slant upwards. While the outer corners of most eyes usually turn downward, those with Down Syndrome have eyes that turn upward (almond-shaped). In addition, doctors may recognize what are known as Brushfield spots, or harmless brown or white flecks in the iris of the eyes. There may also be skin folds present between the eyes and nose. These can resemble eye bags. People with Down Syndrome tend to have smaller ears that are set lower on the head. Some may have ears whose tops fold over slightly. Due to low muscle tone, the mouth may appear to be turned downward and the tongue may protrude from the mouth. Teeth may come in later and in a different order than usual. Teeth may also be small, unusually shaped, or out of place. An orthodontist can help straighten crooked teeth once a child is old enough. Children with Down Syndrome may wear braces for a long time.

SUMMARY: Look for a small, flat nose. Look for slanted eye shape. Look for small ears. Look for an irregularly shaped mouth, tongue, and/or teeth.

In one sentence, describe what the following article is about: heck your blood glucose level. Follow the same procedure each time to check and document your blood glucose levels. Wash your hands thoroughly with soap and water, and dry them with a clean towel. Insert a test strip into your blood glucose meter device. Use your lancet device to obtain a small drop of blood from the fleshy part of your finger. Some newer devices can obtain a droplet from other areas such as your forearm, thigh, or fleshy areas on your hand. Refer to the user manual to proceed properly according to the way your device works. Most devices are spring loaded that help to reduce the pain of pricking your skin. Allow the blood droplet to contact the test strip at the indicated place either before or after it is inserted in the meter, again depending on the way your device works. Your blood glucose level will appear in the window of your device. Record your blood glucose level on your log, along with the time of day you checked it. Checking your blood glucose is the primary tool for both you and your doctor to use in determining the most appropriate dose of insulin you need. By keeping a log of your blood glucose levels, and other variables such as alterations in your diet or additional injections prior to meals or special events where you will consume sugary foods, your doctor can help to improve the control of your diabetes. Take the log with you to each appointment for your doctor to review. Your doctor or diabetic healthcare provider advise you on the targets for your blood glucose levels specific to your condition. General target ranges include 80 to 130mg/dl if taken before a meal, and less than 180mg/dl if taken one to two hours after a meal. Remember that monitoring your blood glucose levels are extremely helpful in tailoring your overall treatment plan, but they are not a judgment of how well you are taking care of your condition. Do not let the results frustrate you. Talk to your doctor if your levels are consistently higher than recommended so you and your doctor can adjust your insulin dose accordingly.
Summary: . Keep a log. Compare your level to the target range.

In one sentence, describe what the following article is about: This will tell your teacher what to expect from the letter. For example, you may be writing your teacher a letter of appreciation. Say, "I am writing this letter to tell you how happy I am to be in your class because you are the best teacher. This year has been hard, but you helped me do my best." Consider why you are writing the letter, then choose the best examples to show your teacher what it is that you appreciate about them. To make your letter more personal, be specific and tell them how their actions made you feel. You could write, "I appreciate the time you spent tutoring me after school. I felt like I would never understand multiplication, but you never let me give up. I'm so happy you're my teacher!" If you're having trouble deciding what to say, grab a sheet of scratch paper and do some brainstorming. Write down reasons why you like your teacher, times that they've helped you, or what you've learned from them. Then pick a few of your favorite reasons and use those in your letter. Write 1 to 3 sentences that sum up what you've said. Remind your teacher that you are appreciative of what they've done for you. You could say, "Thank you for being a great teacher this year. I'm so happy I got to be in your class. I hope you have an incredible summer!"
Summary:
Start with 1 to 2 sentences telling your teacher what the letter is about. Give your teacher a few examples of what you appreciate about them. Finish the body of your letter by thanking them again.
