Bacteria X has a growth rate of 190 % per hour. Some amount of
bacteria X are accidentally introduced into some twirly macaroni
salad. Three hours after contamination, there were 50,000 bacteria
X in the twirly macaroni salad.
Find the initial number of bacteria X introduced into the twirly
macaroni salad:

The growth rate at t = 0 hours is bacteria per hour. When a bactericide is added to a nutrient broth in which bacteria are growing, the bacterium population continues to grow for a while, but then stops growing and begins to decline. The size of the population at time t (hours) is b = 65 +63t - 6242. Find the growth rates at t = 0 hours, t = 3 hours, and t = 6 hours. The growth rate...
