The coefficients are: 2, 12, 4.
Step-by-step explanation:
1/5, 0.4, 1/2, 0.75
Just convert all of them to decimals first then it should be easy or you .
Alright so I got A=4, B=5 and C=9

Answer:
6.2
Step-by-step explanation:
We presume your "k-value" is the k in the exponential decay term ...
e^(-kt) . . . where t is the number of time units
This is 1/2 when ...
ln(1/2) = -kt
t = ln(1/2)/(-k) = ln(2)/k
t = 0.69315/0.1124 ≈ 6.2
The half life is about 6.2 time units.
