A radio substance decays from 60mg to 6mg in 26 years according to the exponential decay model where a is the initial amount and y is the amount remaining after x years.

Find the b-value.


b=


Use the EXACT b-value to write the exponential decay model for this substance with initial amount 60mg, then use that model to find the half-life.

find the half-life. Round to the nearest hundredth of a year, if needed.


half-life= years
