Question
Scientists are studying two bacteria cultures in a lab. The first culture (Q1) grows at a rate of 48%
every hour. If the initial quantity is 90 , complete the following function describing Q1 as a function
of t.
Q1(t)
= 90 ·
The second culture (Q2) decays by 38% every hour. If the initial quantity is 90 , complete the
following function describing Q2 as a function of t.
Q2(t) = 90 -
What is the relationship between the percent that a quantity changes every hour and the value of B
in the formula Q(t) = A · B* ?
