Suppose that a drug is administered to a person in a single dose, and assume that the drug does not accumulate in body tissue, but is excreted through urine. Denote
the amount of drug in the body at time t by x1(t) and in the urine at time t by x2(t). If x1(0) = 5 mg and x2(0) = 0, find x1(t) and x2(t) if dx1/dt = -0.1x1.
Based on the given information, the equation
dx1/dt + dx2/dt = 0
must be satisfied.
Find x1(t) and x2(t).
x1(t) =
x2(t) =
(Type expressions using t as the variable. Use integers or decimals for any numbers in the expressions.)
