A sample of a certain isotope takes 29 years to decay to half its original mass. The function \( s\left(t\right)=184\left(0.5\right)^{\frac{t}{29}} \) gives the approximate mass of this isotope, in grams, that remains t years after a 184-gram sample starts to decay. Which statement is the best interpretation of \( s\left(58\right)=46 \) in this context?
