Question

A radio active isotope decays according to the exponential decay equation where t is in days.
Round to the thousandths place.
For the half life: The half life is the solution (t) of the equation : a/2=ae^−3.392t

Answer 1

hold up im looking for a teacher on this one

Answer 2

e^(-6.345t)=1/2
t=0.11 days


ok so my teacher wrote this down on my paper, it dosent make sense to me
@AceSpeedFighter do you know this?

@devincoolage1001 do you know this

Answer 5

Are we assuming the variable a is not representing the initial value on the right hand side of the equation and that a is not representing the final value in mass of the substance on the left hand side?

Answer 6

If a is the same variable on both sides of the equation then you could actually solve for t. However, that doesnt seem likely given the question appears to be missing information.
