Problem

The number of bacteria in a certain population increases according to a continuous exponential growth model, with a growth rate parameter of $1.1 \%$ per hour. How many hours does it take for the size of the sample to double? Español Note: This is a continuous exponential growth model. Do not round any intermediate computations, and round your answer to the nearest hundredth. $?$ $\square$ \begin{tabular}{|c|c|} \hline$x$ & 5 \\ \hline \end{tabular}

Solution

Step 1 :The continuous exponential growth model is given by the formula \(N(t) = N_0 * e^{rt}\), where \(N(t)\) is the final amount, \(N_0\) is the initial amount, \(r\) is the growth rate, and \(t\) is the time.

Step 2 :In this case, we want to find the time it takes for the population to double, so \(N(t) = 2*N_0\).

Step 3 :We can set up the equation \(2 = e^{1.1/100 * t}\) and solve for \(t\).

Step 4 :Let \(r = 0.011000000000000001\)

Step 5 :Solving the equation gives \(t = 63.01338005090411\)

Step 6 :Rounding to the nearest hundredth, the final answer is \(\boxed{63.01}\) hours.
