For a short time after a wave is created by wind, the height of the wave can be modeled using y = a sin 2πt/t , where a is the amplitude and t is the period of the wave in seconds.

part 1: write an equation for the given function given the amplitude, period, phase shift, and vertical shift.
amplitude = 4 , period = 4π , phase shift = -4/3 π , vertical shift = -2

part 2: write an equation for the given function given the period, phase shift, and vertical shift.
cotangent function, period = π , phase shift = -1/3 π , vertical shift = 2

Adoctor administers a drug to a 38-kg patient, using a dosage formula of 50 mg/kg/day. assume that the drug is available in a 100 mg per 5 ml suspension or in 500 mg tablets. a. how many tablets should a 38-kg patient take every four hours? b. the suspension with a drop factor of 10 ggt/ml delivers the drug intravenously to the patient over a twelve-hour period. what flow rate should be used in units of ggt/hr? a. the patient should take nothing pills every four hours. (type an integer or decimal rounded to the nearest hundredth as needed.)
