Natural Exponential

OpenStudy (studygurl14):

\[D(t) = 20e^{-0.2t}\] \[D(5) = 20e^{-0.25}\] solve.

OpenStudy (anonymous):

would the first one be 16?

OpenStudy (anonymous):

and the second one 15.57? @StudyGurl14

OpenStudy (studygurl14):

I just plugged 5 in as t \[D(5) = 20e^{-0.2(5)}\] \[D(5) = 20e^{-1}\] Can you do the rest now?

OpenStudy (anonymous):

so it would be 7 milligrams ?
