Transcribed Image Text:Do ONE of the following:
(a) Bacterial population A is growing exponentially while B is shrinking exponentially.
At time t-0, population A has 3000 cells and population B has 9000 cells. If the two
populations have the same number of cells at t=5 what is the ratio of population A to
population B at t=15?
(b) Find the volume bound by the curves
x = 2y? – 3y – 3 and a =
= -y? +3
if they are rotated around the line
y = -2.
(c) Evaluate:
/sec" (a)dz .
