105 degree , I think but not sure
After 2.0 years, the 4.0 mg sample decays to 2.0 mg.
After another 2.0 years (total 4.0 years), the 2.0 mg sample decays to 1.0 mg.
And after another 2.0 years (total 6.0 years), the 1.0 mg sample decays to 0.50 mg.
So it takes 6.0 years for 4.0 mg to decay to 0.50 mg.
11+10=?????????????????????
An equation is y = 2x-1
And then draw a line or something to show that the equation is true
It would be the first one because it’s going up by a constant rate
