Answer:
The table doesn't display a linear relationship because the slope doesn't stay constant throughout the whole table.
Okay so i subtract and then i got my number 125 as the total answer
1,2,3,4,5,6,10,12,15,60 I believe
Answer:
193 mg
Step-by-step explanation:
Exponential decay formula:

- where Aₜ = mass at time t, A₀ = mass at time 0, r = decay constant (rate), t = time
Our known variables are:
- 1998 to the year 2004 is a total of t = 6 years.
- The sample of radioactive isotope has an initial mass of A₀ = 360 mg at time 0 and a mass of Aₜ = 270 mg at time t.
Let's solve for the decay constant of this sample.
Using our new variables, we can now solve for Aₜ at t = 7 years, since we go from 2004 to 2011.
Our new initial mass is A₀ = 270 mg. We solved for the decay constant, r = 0.04794701.
The expected mass of the sample in the year 2011 would be 193 mg.
I think it is 100, maybe.
