Robbie deposits 1000 into a bank account. the bank credits interest at a nominal annual rate of j convertible semiannually for the first 7 years and a nominal annual rate of 2j convertible quarterly for all years thereafter. the accumulated amount in the account at the end of 10.5 years is 1980. calculate the accumulated amount in the account at the end of 5 years

Use the knowledge of x- and y- intercepts to choose the correct graph of the equation 3x+6y=6

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.)

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2
