Plz could you also provide a graph as well

A single oral dose of 500 mg is adminstered and the concentration after t hours is given by C(t) = 185 (e- 0.05/81 -e 2.1foot ) mcg/mL. Suppose this dose is repeated every 12 hours. (a) Find the steady-state concentration function C (t). (b) Find the maximum steady-state concentration ( Com (c) How long after the dose is taken does this maximum occur? Enter your answer with at least two decimal places. (d) Find the minimum steady-state concentration ( Co.min ). (e) When does this minimum occur? (Note: There are two correct answers to this question. Enter the smaller time in the first answer box, then the larger time in the second answer box.) ... Enter c values as integers and t values with two decimal places. (a) Coo (t) = e-0.0578t - e-2.7700t mcg/ml (b) Coo.max = mcg/ml (c) tmax = hours
