Question 1006210: Solve the given problem related to population growth.
The number of bacteria N(t)present in a culture at time t hours is given by
N(t) = 1200(2)^t.
Find the number of bacteria when
t = 0 hours and t = 5 hours.
(a) t = 0 hours
=Bacteria
(b) t = 5 hours
=Bacteria

+N%28t%29+=+1200%2A2%5Et+
(a)
+t+=+0+ hrs
+N%280%29+=+1200%2A2%5E0+
+N%280%29+=+1200%2A1+
( any number raised to the zero power = 1 )
+N%280%29+=+1200+
--------------------
(b)
+t+=+5+ hrs
+N%285%29+=+1200%2A2%5E5+
+N%285%29+=+1200%2A32+
+N%285%29+=+38400+
