Suppose the drug atenolol is taken in 50 mg doses once a day to lower blood pressure. at the end of a 24 hour period, approximately 7 % of the atenolol is still present. (a) find expressions for the quantities q1, q2, q3, . ., and qn , representing the amounts of atenolol in the body right after taking the 1st, 2nd, 3rd doses respectively. then write the expression for qn in closed-form. q1 = 50 q2 = 53.5 q3 = 53.745 qn = (b) find expressions for the quantities p2, p3, p4, . ., and pn representing the amount of atenolol in the body right before taking the 2nd, 3rd, 4th doses respectively. then write the expression for pn i
