Dovator [93]

Answer:

Population of bacteria four hours later A=616.5187  or nearest whole number

A=616

Step-by-step explanation:

Given,

Let amount of bacteria four hours later is=A

Rate of increase of bacteria per hour  =\frac{\partial x}{\partial t}=4.0565e^{1.3t}

Initial population of bacteria is =54

Time 4 hours

Find the population of bacteria 4 hours later

Solution,

\int_{54}^{A}dx=\int_{0}^{4}4.0565e^{1.3t}dt

\left [ x \right ]_{54}^{A}=4.0565/1.3\left [e^{1.3t}  \right ]_{0}^{4}

A-54=4.0565/1.3\left ( e^{1.3\times 4} -1\right )

A-54=562.5187301

A=562.5187301+54

A=616.5187

Population of bacteria 4 hours later isA=616
