Situation: Find the substance's half-life, in days.
Round your answer to the nearest tenth.
A 10 gram sample of a substance that's
used to detect explosives has a k-value
of 0.1353.
Enter the correct answer.
DONE
-kt
N - Noe
No - initial mass (at time t = 0)
N = mass at timet
k = a positive constant that depends on
the substance itself and on the units
used to measure time
t - time, in days
