I think the answer to this is A
Answer:
The rock is 3.75 billion years ago.
Explanation:
Given that:
Half life = 1.25 billion years
1 billion years = 10⁹ years
So,
Half life = 1.25 × 10⁹ years

Where, k is rate constant
So,


The rate constant, k = 5.5452 × 10⁻¹⁰ years⁻¹
Initial amount [A₀] = 80 micrograms
Final amount
= 10 micrograms
Using integrated rate law for first order kinetics as:
![[A_t]=[A_0]e^{-kt}](https://tex.z-dn.net/?f=%5BA_t%5D%3D%5BA_0%5De%5E%7B-kt%7D)
So,





So,
<u>The rock is 3.75 billion years ago.</u>
Panettone is the type of sweet bread loaf which originated in Milan and is traditionally eaten at Christmas in Italy and many other European countries.
Panettone is one of the symbols of Milan.
The word "panettone" is derived from the Italian word "panetto" meaning a small loaf cake. Adding the Italian suffix "-one" to the word "panetto" changed its meaning into "large cake".
Panettone became the country's leading Christmas sweet by the end of World War II because fierce competition between two Milanese bakers in baking the panettone led to an industrial production of the cake making it cheaper and available for everyone.
