Model the situation with a dynamical system. Use your model to answer the question. 12) You take a 259-mg dose of an antibiotic every 5 hours. Your body eliminates 44% of the drug in a 5-hour period. How much antibiotic will be in your bloodstream after two doses? A) Dn+1 = 56Dn + 259, n = 0, 1, 2, .., where Do = 0; 14,763.00 mg B) Dn+1 = 0.56 D n + 259, n = 0, 1, 2, .., where Do = 259; 663.04 mg C) Dn+1 = 0.56D + 259, n = 0, 1, 2, ..., where Do = 0; 404.04 mg %3D %3D %3D %3D %3D %3D %3! D) Dn+1 = 0.44Dn + 259, n = 0, 1, 2, .., where Do = 0; 372.96 mg %3D %3!

Sodium Pentathol Elimination Ed is undergoing surgery for an old football injury and must be anesthetized. The anesthesiologist knows Ed will be "under" when the concentration of sodium pentathol in his blood is at least 50 milligrams per kilogram of body weight. Suppose that Ed weighs 1 00 kg (220 pounds) and that sodium pentathol is eliminated from the bloodstream al a ra1e proponional 10 lhe amount present. If the half-life of 1he drug is 10 hours, whal single dose should be given to keep Ed anesthetized for three hours?
