A tank contains 200 litres of fluid in which 60 grams of salt is dissolved. A brine solution of 2 grams of salt per litre is pumped into the tank at a rate of 2 litres/minute. The well-stirred solution is then pumped out at the same rate.
(a)Write the differential equation in terms of Q(t) and t and write the initial condition to model this
problem. (Q(t) should represent the amount of salt in the tank at time t).
(b)Solve the equation in part (a).
(c)How much salt will be present in the tank after a long period of time?

◦
(a) = 400 - ,   Q(0) = 60(b) Q(t) = 40 - 34 e-t/100(c) 40 grams

◦
(a) = 2 - ,   Q(0) = 60(b) Q(t) = 200 - 340 e-t/100 c) 200 grams

◦
(a) = 4 - ,   Q(0) = 60(b) Q(t) = 400 - 340 e-t/100 (c) 400 grams

◦
(a) = 400 - Q(t),   Q(0) = 60(b) Q(t) = 400 - 340 e-t (c) 400 grams

◦
(a) = 400 - ,  Q(0) = 60(b) Q(t) = 4 - 3.4 e-t/100 (c) 4 grams

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.

Hypertension is a silent killer because it is deadly and has no significant early symptoms. The danger from hypertension is the extra load on the heart, which can lead to hypertensive heart disease and kidney damage. This occurs without any major symptoms until the high blood pressure becomes extreme. Regular blood pressure checks are an important method of catching hypertension before it can kill you.
