3. A culture of bacteria obeys the law of uninhibited growth. (a) (10 points) Suppose that 700 bacteria are present initially and there are 1200 bacteria after 2 hours. How many bacteria will be present after 10 hours? Formula : A = Aockt 1) 1,200 = 70 0 ek ( 10 ) 2 ) 1 , 200 = 70 0 ek = > 1.71 = ek 3) K = In (1.71 ) ~ 0.54 4 ) A = 700 e 10. 54) (10) ~ / 154, 984 bacteria (b) (15 points) How long will it take for the number of bacteria to grow to 75% of the initial amount
