Differential equation- solve with complete solution.Please write legibly

Lake Taal has a volume of 458 cubic
km, and its rate of inflow and outflow
are both 175 cubic km/year. Suppose
that the time t=O (years), its pollutant
concentration is 0.06 %, and that
thereafter the concentration of
pollutants in the inflowing water is
0.01 %. Assuming that the outflow is
perfectly mixed lake water, find the
initial-value problem and how long
will it take to reduce the pollution
concentration in the lake at 0.03 %? *

A river flows into and out of the lake at a rate of 20000 cubic meters per hour. Assuming that the entering river contains fresh water and that the toxic substance is fully mixed throughout the lake at all times, find the number of hours for the mass of the pollutant to decrease to an acceptable 100 kilograms.

5. Suppose that sodium pentobarbital is used to anesthetize a dog. The dog is anesthetized when its bloodstream contains at least 45 milligrams (mg) of sodium pentobarbitol per kilogram of the dog's body weight. Suppose also that sodium pentobarbitol is eliminated from the dog's bloodstream at a rate which is proportional to the amount of sodium pentobarbitol in the bloodstream and that after 5 hours half of the initially prescribed sodium pentobarbitol is elliminated from the bloodstream. Set up and solve an initial value differential equation. What single dose should be administered in order to anesthetize a 50-kg dog for 1 hr?

In bucolic farm there a contagion spreading among 500 happy cows, some with spots others with- out. There are no other breeds of cows in the field. The contagion spreads through contact. Cows without spots that come in to contact with cows with spots immediately develop spots. Assume that during the modeling period the effects are immediate and permanent (spotted cows remain spotted). It is reasonable to assume that the rate at which cows develop spots is proportional to the product of the number of spotted cows and the number of non-spotted cows. Let S = S(t) be the number of spotted cows at time t. Write a differential equation reflecting the situation.
