A chain smoker smokes five cigarettes every hour. From each cigarette, 0.4 mg of nicotine is absorbed
into the person’s bloodstream. Nicotine leaves the body at a rate proportional to the amount present,
with constant of proportionality -0.346 if t is in hours.
a. Write a differential equation for the level of nicotine in the body, N, in mg, as a function of time, t,
in hours.
b. Solve the differential equation and graph the solution. Initially there is no nicotine in the blood

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
