If a hospital patient is given 50 milligrams of medicine which leaves the bloodstream at 10% per hour, how many milligrams of medicine will remain in the system after 6 hours? Use the function A(t) = Iert. 12. 39 mg 27. 44 mg 45. 24 mg 91. 11 mg.

Respuesta :

The amount of medicine that will remain in the system after 6 hours is 27.44 milligrams.

Given to us

Initial condition = 50 milligrams of medicine,

Rate at which medicine will be disposed = 10% = 0.1

function = [tex]A(t) = I \times e^{rt}[/tex]

To find

Medicine remains in the system after 6 hours

As the function is already given to us, substituting the values in the function we get,

[tex]A(t) = I \times e^{rt}[/tex]

[tex]A(t) = (50) \times e^{(-0.1\times 6)}[/tex]

the value of r is -0.1(10%) because the medicine is leaving the system, therefore, the value of medicine will be reduced.

Solving the function further,

[tex]A(t) = (50) \times e^{(-0.1\times 6)}\\A(t) = 27.44\ milligrams[/tex]

Hence, the amount of medicine that will remain in the system after 6 hours is 27.44 milligrams.
