<span>We are given f(1) = 0 and f(2) = 1.
Going forward, the term is the sum of the two previous terms.
f(3) = f(2) + f(1) = 0 + 1 = 1.
f(4) = f(3) + f(2) = 1 + 1 = 2
f(5) = f(4) + f(3) = 2 + 1 = 3
This matches answer B.</span>
Given that the concentration has been modeled by the formula: C(t)=50t/(t^2+25) where: t is time in hours. The concentration after 5 hours will be given by: t= 5 hours plugging the value in the equation we get: C(5)=(50(5))/(5^2+25) simplifying the above we get: C(5)=250/(50)=5 mg/dl
