Question 1178216: As a sample of a radioactive element decays into more stable elements, the amount of radiation it gives off decreases. The level of radiation can be used to estimate how much of the original element remains. The following are some readings for a sample of radium-227:
(a)Which of these two models (quadratic or exponential) fits the data best? Justify your answer.
(b) According to each model, what amount of radium-227 will remain after 8 hours?
c) Which of these two models is superior for extrapolating beyond 6 h? Explain.
Time( h) | Radiation level (%)
0 | 100
1 | 37
2 | 15
3 | 5.0
4 | 1.8
5 | 0.7
6 | 0.3

You can put this solution on YOUR website! .
On contrary with the text, only ONE model is presented in the post.
So, make the text consistent with the meaning.
Do not make it CONTRADICTORY to the meaning.
Also, keep in mind that this forum is not a Psychic clinics,
so if I see this text posted again with no change, I will delete it IMMEDIATELY without any explanations.
