C would be the correct answer because a claim of fact is trying to get a point across or prove something you believe.
Unopposed they would be running against the same party
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:
So,
So,
<u>The rock is 3.75 billion years ago.</u>
I think it is D mild I am just guessing.
