The exponential function should be written as:
\n" ); document.write( "\"A%28t%29+=+200e%5E%28-0.014t%29\"
\n" ); document.write( "gives the amount of medication, in milligrams, in a patient's bloodstream t minutes after the medication has been injected into the patient's bloodstream.
\n" ); document.write( "(a) Find the amount of medication, to the nearest milligram, in the patient's bloodstream after 35 minutes._______mg
\n" ); document.write( "\"A%28t%29+=+200e%5E%28-0.014%2A35%29\"
\n" ); document.write( "\"A%28t%29+=+200e%5E%28-.49%29\"
\n" ); document.write( "A(t) = 200*.6126
\n" ); document.write( "A(t) = 122.5 mg
\n" ); document.write( ":
\n" ); document.write( "(b) Use a graphing utility to determine how long it will take, to the nearest minute, for the amount of medication in the patient's bloodstream to reach 50 milligrams._________min
\n" ); document.write( "Graph equation: y = 200*e^(-.014x)
\n" ); document.write( "\"+graph%28+300%2C+200%2C+-60%2C+170%2C+-100%2C+180%2C+200%2Ae%5E%28-.014x%29%2C+50%29+\"
\n" ); document.write( "Amt of 50 mg will occur at 99 minutes (green line is 50 mg)
\n" ); document.write( "
