Cobalt-60 is used in the treament of cancer. A sample contains 8 grams of Co-
60 where k - 0.1308.
N = Noe
-kt
No - initial mass (at time t = 0)
N = mass at time t
k - a positive constant that depends on
the substance itself and on the units
used to measure time
t-time, in days
Find the half life, in days of co 60. Round you answer to the nearest tenth
