    Can someone help me with this please
    6. In an experiment, the number of bacteria, N, in a culture was estimated at time t days after the measurements started.
    The results were as follows:
    t 1 2 3 4 5 6
    N 120 170 250 400 620 910
    It is believed that the relationship between N and t can be expressed in the
    form where a and b are constants.
    N=ab/\t (to the power t)
    (i) Explain how this can be tested by plotting log N against t. [2]
    (ii) Make out a table of values of log N and draw the graph. [3]
    (iii) Use your graph to estimate the values of a and b. [3]
    (iv) Estimate the number of bacteria present after 20 days.
