What is the halflife

Mathematics
1 answer:
blagie [28]3 years ago
5 0
To model half-life, use the formula A(t)=A_0 (\dfrac{1}{2})^{ \frac{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( \frac{1}{2})^{25/50} = 10( \frac{1}{2})^{1/2} = 7.07 \ grams.
