A certain drug is eliminated from the bloodstream with a half-life of 32 hours. Suppose that a patient receives an initial dose of 70 mg of the drug at midnight. a. How much of the drug is in the patient's blood at noon later that day? b. When will the drug concentration reach 25% of its initial level? a. The reference point is midnight. If t is measured in hours, what is the exponential decay function? y(t) = (Type an expression. Do not round until the final answer. Then round coefficients to six decimal places as needed.)

x?(t) = e^{j2?t} = cos 2?t + j sin 2?t, x?(t) = e^{j3?t} = cos 3?t + j sin 3?t and x?(t) is a continuous signal satisfying |x?(t)| < 1. Answer the following questions: (1) Determine if the signals y(t) = 1 + x?(t) + x?(t), z(t) = x?(t) + cos 2t, w(t) = \frac{1 + x?(t)}{x?(t)} are periodic or non-periodic. Also, find the fundamental period of each signal that is periodic. (2) Is f(t) = \frac{x?(t) - x?(-t)}{2 + x?(t) + x?(-t)} an even or odd signal?
