Answer:
C) a^4
Step-by-step explanation:
I think it’s this answer because you have to subtract the 6 from the 2. A just stays the same.
364 ÷ 2800 = 0.13.
Multiplying 0.13 by 100, we get 13.
Answer: 13%
Answer:
Step-by-step explanation:
This almost should be reported. But here is the graph you are looking for.
It has to have a y intercept of about -2 and an x intercept of 9.
Answer:
3.12 kg.
Step-by-step explanation:
Mass after t years:
The mass of the elements after t years is given by the following equation:
In which M(0) is the initial mass and r is the decay rate, as a decimal.
The half life of Cs-137 is 30.2 years.
This means that:
We use this to find r.
So
If the initial mass of the sample is 100kg, how much will remain after 151 years?
This is M(151), with M(0) = 100. So
The answer is 3.12 kg.
