A new class of antibiotics is studbu o)i5rs gv3 xy(tb*o2(e:jq ied in the met d(e:ei j 1d aygk1ny:0v)wq1dical research center. Antibiotics are applied to a pure culture of bacteria. The number of bacteria, N, present in the cultv g)e:d1ti(ej 0 akyw:ny1dq1ure 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 researcher in the center claims that the number of bacteria, N, left in the culture afterafter applying antibiotics can be modelled by an exponential function of the form N(t)=a×bt, where a and b are positive constants.
4.Explain why the researcher is correct.
5.Find the value of a and the value of b. a ≈ b ≈
