Answer: The age of the fossilized leaf is 13829 years.
Step-by-step explanation:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = age of sample
a = let initial amount of the reactant = 100
a - x = amount left after decay process =
a) for completion of half life:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
b) for finding the age
The age of the fossilized leaf is 13829 years.
Well 15 is over 8 so figure out how many times 8 goes into 15 then the rest of 15 replaces it over the 8
13) f(x) = a ( x + 2 ) - 7
14) f(x) = 3 ( x - 5 ) + 2
