SOLUTION: Assume that the number of viruses present in a sample is modeled by the exponential function "f(t) 10^t," where t is the elapsed time in minutes. How would you apply logarihm to d

Question 126365: Assume that the number of viruses present in a sample is modeled by the exponential function "f(t) 10^t," where t is the elapsed time in minutes. How would you apply logarihm to determine when the sample will grow to 5 billion viruses?

f(t)= 10^t," where t is the elapsed time in minutes. How would you apply logarihm to determine when the sample will grow to 5 billion viruses?
----------------
5x10^9 = 10^t
Take the log of both sides to get:
9 + log5 = t
t = 9.69 minutes
