A particular species of mic6q: cec,3h vijb 1xptlad;g// rork.bti 3p7rld.eew i*:q 3lxui7*(brbes is studied in the laboratory. Microbes are grown under controlled conditions in purp 3:r. x( ieiqi *berr3ulkl7tdwb7*.e culture. The number of microbes, N, present in the culture t hours after the start of the experiment are recorded. The results are shown in the table below.
1.Complete the third row of the table above.
2.Draw a scatter diagram of logN versus t, scaling the axes if needed.
3.State the type of model that best fits the data displayed on your scatter
diagram from part (b).
A scientist in the laboratory claims that the number of microbes, N, grown in the laboratory during the experiment can be modelled by an exponential function of the form N(t)=a$\times$$b^t$, where a and b are positive constants.
4.Explain why the scientist is correct.
5.Find the value of a and the value of b. a ≈ b ≈
