Few remedies are more effective than resting in order to allow your body to recover. Not getting enough sleep, or continuing to work or go to school while sick can make your illness worse. This will help to moisten and soothe your throat. It will also thin any mucus that may be causing discomfort. Run the shower to steam up your bathroom and sit in the steam for 5 to 10 minutes. The warm, moist air will help to soothe your throat. Contact your doctor earlier if you or your child have swollen glands, a fever (above 100.4 degrees F), and severe throat pain or if you have been around someone with strep throat and have a sore throat. Consult your doctor if you have strep throat and are getting worse or not better after 2 days of antibiotics or if you have new symptoms such as a rash, swollen joints, decreased or dark colored urine, or chest pain or trouble breathing. Children with large tonsils are more prone to sore throats and ear infections. If your child has frequent tonsil infections – 7 or more times in 1 year, or 5 or more times over 2 years – you should talk to your doctor about a possible tonsillectomy – a low-risk, out-patient procedure to remove the tonsils.

Summary: Rest. Turn on a cool mist humidifier while you sleep. Steam up your bathroom. Call your doctor if your sore throat persists for more than 24-48 hours. Discuss having your child’s tonsils removed if he or she has frequent tonsillitis or strep throat.


Let's say your problem is "The bike begins traveling to the right at 5 m/s, constantly accelerating at 2 m/s2. If it travels for 5 seconds, what is its average velocity?" If the unit "m/s2" makes no sense to you, write it as "m/s/s" or "meters per second per second." An acceleration of 2 m/s/s means the velocity increases by 2 meters per second, each second. Acceleration, written a, is the rate of change in velocity (or speed). The  velocity is rising at a constant rate of increase. You can draw a table using the acceleration to find out the velocity at different moments during this journey. We'll need to do this for the final moment in the problem (at t = 5 seconds), but we'll write a longer table to help you grasp this concept:  At the beginning (time t = 0 seconds ), the bike is traveling right at 5 m/s. After 1 second (t = 1), the bike moves at 5 m/s + at = 5 m/s + (2 m/s2)(1 s) = 7 m/s. At t = 2, the bike is moving right at 5+(2)(2) = 9 m/s. At t = 3, the bike is moving right at 5+(2)(3) = 11 m/s. At t = 4, the bike is moving right at 5+(2)(4) = 13 m/s. At t = 5, the bike is moving right at 5+(2)(5) = 15 m/s. If and only if the acceleration is constant, the average velocity is the same as the average of the final velocity and the initial velocity: (vf + vi)/2. For our example, the bike's initial velocity vi is 5 m/s. As we worked out above, it ends up traveling at a final velocity vf of 15 m/s. Plugging these numbers in, we get (15 m/s + 5 m/s) / 2 =  (20 m/s) / 2 = 10 m/s right.  Remember to include the direction, in this case "right." These terms can instead be written as v0 (velocity at time 0, or initial velocity), and simply v (final velocity). To find the average velocity, we could take the velocity at every single moment and find the average of the entire list. (This is the definition of average.) Since that would require calculus or infinite time, let's build off of this for a more intuitive explanation instead. Instead of every moment in time, let's take the average of the velocity at just two points in time and see what we get. One point in time will be near the beginning of the journey, when the bike is traveling slow, and the other will be equally close to the end of the journey, when the bike is traveling fast. Use the table above for the velocities at different points in time. Some of the pairs that fit out criteria are at (t=0, t=5), (t=1, t=4), or (t=2, t=3). You can test this with non-integer values of t as well, if you like. No matter which pair of points we choose, the average of the two velocities at those times will always be the same. For example, ((5+15)/2), ((7+13)/2), or ((9+11)/2) all equal 10 m/s right. If we used this method with a list of every moment in time (somehow), we would keep averaging one velocity from the first half with one velocity from the second half of the journey. There's an equal amount of time in each half, so no velocities would be unaccounted for after we were finished.  Since any one of these pairs average to the same amount, the average of all these velocities will be equal to this amount. In our example, the average of all of those "10 m/s right" will still be 10 m/s right. We can find this amount by averaging any one of these pairs, for instance the initial and final velocities. In our example, those are at t=0 and t=5, and can be calculated using the formula above: (5+15)/2 = 10 m/s right. If you're more comfortable with a proof written as formulas, you can start with the formula for distance traveled assuming constant acceleration, and derive this formula from there:  s = vit + ½at2. (Technically Δs and Δt, or change in position and change in time, but you'll be understood if you use s and t.) Average velocity vav is defined as s/t, so let's put the formula in terms of s/t. vav = s/t = vi + ½at Acceleration x time equals the total change in velocity, or vf - vi. So we can replace "at" in the formula and get: vav = vi + ½(vf - vi). Simplify: vav = vi + ½vf - ½vi = ½vi + ½vf = (vf + vi)/2.

Summary: Note the initial velocity and constant acceleration. Use acceleration to find the final velocity. Use this formula to find average velocity. Understand the average velocity formula intuitively. Test out the intuitive theory. Finish the intuitive explanation. Understand the formula mathematically.


Enlist friends, family, and classmates to help. Let them know the kind of job you’re looking for so they can tell you when they see a position that might fit you. Start searching the job classifieds online. Craigslist, monster.com, indeed.com, and other regional sites (depending on where you live) are going to have a wide cross-section of jobs to which you could apply. If you are interested in particular companies, check their websites (usually the Human Resources section) to see if they have openings. If you don’t have the qualifications they are looking for, don’t apply. It’s a waste of your time and their time. Most jobs now have so many applicants, anyone who is not completely what they are looking for will be disqualified. Make sure your letter properly reflects the job to which you are applying.
