Answer:
The age of paintings is - 26,601 years .
Step-by-step explanation:
Lets calculate-
A= [tex]0.25 A[/tex]o
Therefore ,
[tex]A= A[/tex]o [tex]e^-^0^.^0^0^0^1^2^1^t[/tex]
[tex]ln0.25=-0.000121t[/tex]
[tex]-3.2188=-0.000121t[/tex]
[tex]t=\frac{-3.2188}{-0.000121}[/tex]
t= 26,601.65
Therefore , the age of paintings is 26,601 years old.
