A bacteria culture starts with 1000 bacteria. 2 hours later there are 1500 bacteria. How do you fin an exponential model for the size of the culture as function of time t in hours, and use the model to predict how many bacteria there will be after 2 days?
So and exponential growth or decay will fit the formula,
so we sub in what we know
so our population is modelled by,
so 2 days is 48 hours so subbing in,
