When a bactericide is added to a nutrient broth in which bacteria are growing, the bacterium populationcontinues to grow for a while, but then stops growing and begins to decline. The size of the population attime t (hours) is b = 106 + 104t - 10³12. Find the growth rates at t=0 hours, t=5 hours, and t= 10 hours. The growth rate at t=0 hours isThe growth rate at t=5 hours isThe growth rate at t= 10 hours isbacteria per hour.bacteria per hour.bacteria per hour
