Split 60 minutes into 3 groups. 20+20+20=60 minutes. 20 minutes
The Answer is -69 because if you lay out the problem it is -82+50-37=-69
The answer to this question is 6. Hope I helped!
Answer:
14.7
Step-by-step explanation:
Perhaps your equation is ...
f(t) = N·e^(-0.2174t)
We want f(6) = 4, so ...
4 = N·e^(-0.2174·6) = N·e^-1.3044 ≈ 0.2713N
N = 4/0.2713 = 14.7 . . . . milligrams
The dose amount was about 14.7 mg.
