log2(x) = 5.6
so,
x = 2^5.6 ≈ 48.50293013... ≈ 48.50
Answer: 54678 years
Step-by-step explanation:
This can be solved by the following equation:
(1)
Where:
is the quantity of atoms of carbon-14 left after time
is the initial quantity of atoms of C-14 in the mammal hide
is the rate constant for carbon-14 radioactive decay
is the time elapsed
On the other hand, has a relation with the half life of the C-14, which is :
(2)
Substituting (2) in (1):
(3)
Applying natural logarithm on both sides of the equation:
(4)
(5)
Isolating :
(6)
(7) This is the age of the mammal hide
Step-by-step explanation:
=> V = 4/3 π r³
=> V1 : V2 = r³ : r'³
=> 1³ : 5³
=> 1 : 125
