A medical lab technician is monitoring a sample of magnesium-27, which has a half-life of 9.45 minutes. To calculate the remaining amount of the substance over time, they use the exponential decay model $A = A_0 e^{kt}$. According to the model, which equation would they solve first to determine the decay constant $k$?

A medical laboratory technician is tracking a 10-mg sample of magnesium-27, which has a half-life of 9.45 minutes. They need to calculate the amount remaining after 6 minutes using the exponential decay model $A = A_0 e^{kt}$. Match each step of the technician's process with its corresponding mathematical expression or value.

A laboratory technician is tracking the decay of a 10-mg sample of magnesium-27, which has a half-life of 9.45 minutes. Arrange the following steps in the correct order to calculate the amount of the sample remaining after 6 minutes using the exponential decay model $A = A_0 e^{kt}$.

A medical laboratory technician is using the exponential decay model $A = A_0 e^{kt}$ to track the degradation of a sample with a half-life of ${}9.45$ minutes. To solve for the decay rate $k$, the technician must recognize that at $t = 9.45$ minutes, the ratio of the remaining amount to the initial amount, $\frac{A}{A_0}$, is equal to ____.
