Step 1 :We are given the function \(y=y_{0} e^{0.059 t}\) and we want to find the time \(t\) it takes for the size of the sample to double. This means we want to find \(t\) such that \(y = 2y_{0}\).
Step 2 :We can set up the equation \(2y_{0} = y_{0} e^{0.059 t}\) and solve for \(t\).
Step 3 :Let's assume \(y_{0} = 1\) for simplicity. Then the equation becomes \(2 = e^{0.059 t}\).
Step 4 :Solving this equation gives \(t = 11.748257297626193\).
Step 5 :Rounding to the nearest tenth, we get \(t = 11.7\).
Step 6 :Final Answer: It takes approximately \(\boxed{11.7}\) hours for the size of the sample to double.
