Question

What is the halflife

Answer 1

To model half-life, use the formula
`A(t)=A_0 ((1)/(2))^{ (t)/(t_(1/2))`. Here,
`A(t)` is the amount remaining after a length of time
`t`.
`A_0` is the amount that you start with.
`t_(1/2)` is the half-life. You plug in 50 for
`t_(1/2)`, 10 for
`A_0`, and 25 for
`t`. You get
`A(t)=10( (1)/(2))^(25/50) = 10( (1)/(2))^(1/2) = 7.07 \ grams`.
