Jonathan is investigating the spread of a virus measured by the number of daily recorded cases NNN. He believes N=AektN = Ae^{kt}N=Aekt.
Express lnN \ln N\,lnN in terms of ttt
Plot lnN \ln N\,lnN against t t\,t for this data:
| ttt | 8 | 11 | 18 |
|---|---|---|---|
| NNN | 12 | 24 | 90 |
Using the graph, estimate the value of A A\,A and the value of kkk.
