Question

the half life of radium 226 is 1590 years. if a sample initially contains 100mg, how many milligrams will remain after 1 week

can you use the equation y=ab^x

Answer 1

what didn't you like about my solution the previous time you posted this?

Answer 2

nope, cant use the equation given

making a minor adjustment
\[y= a b^{\frac{-x}{h}}\]

where y = amount of product after a given time
a = initial amount of product
b would be 2 because we're refering to half life so it will half every 1590 years

x - amount of time
h - half life time
