(There are 24 hours in a day, so \( t=24 d \).)
(A) \( k(t)=A_{0}(0.5)^{(t / 24)} \)

B
\( k(t)=A_{0}\left(0.5^{(1 / 24)}\right)^{(8 t)} \)
\( k(t)=A_{0}\left(0.5^{(2 t)}\right)^{(t / 8)} \)

\( k(t)=A_{0}\left(0.5^{1 /(182)}\right)^{t} \)

lodine-131 has a half-life of 8 days. In a particular sample, the amount of iodine- 131 remaining after d days can be modeled by the function h given by h(d)=A0(0.5)^(d / 8), where A0 is the amount of iodine131 in the sample at time d=0. Which of the following functions k models the amount of iodine-131 remaining after t hours, where A0 is the amount of iodine-131 in the sample at time t=0 ? (There are 24 hours in a day, so t=24 d.)
(A) k(t)=A0(0.5)^(t / 24)

B
k(t)=A0(0.5^(1 / 24))^(8 t)
k(t)=A0(0.5^(2 t))^(t / 8)

k(t)=A0(0.5^1 /(182))^t
