Mathematics: The number of bacteria in a certain population increases according to a continuous exponential growth model, with a growth rate parameter of 1.4% per hour. how many hours does it take for the size of the sample to double? how do you solve this

5 cups of walnuts are needed.Step-by-step explanation:This question can be solved using a rule of three.One batch of walnut muffins uses 1 1/3 cups of walnuts.So one batch of walnut muffins uses cups of walnuts.How many cups of walnuts are needed to make 3 3/4 batches of muffins?How many cups are required for batches.1 batch - (4/3) cups(15/4) batches - x cups5 cups of walnuts are needed....

Mathematics

If it's growing at the rate of 1.4% per hour, then each hour the sample is 101.4% of what it was previously. So:
1.014^t=2 (to double)
ln 2=ln 1.014^n=t ln 1.014
t =ln 2/ln 1.014=49.85 hours to double.
