Growth of Bacteria: Bacteria grown in a laboratory are inoculated into a broth, and then grown for a period of time. Typically, the growth pattern of any bacterial culture follows a regular pattern. Let Solution Put t=0 u get Po=1 million Put t=450 u get M=100 million as e^rt after this tends to zero as the value of bectaria have beacame constant and use above value Put t=2 10=100/(1+99*e^-2r) 10=1+99*e^-2r 1/root11=e^-r e^r=root11 r=1.19 Now the expression is P(t)=100/(1+99*e^-2*1.19) put t=5 p(5)=9.84Million.
