Q3.

In a science experiment, a quantity Q(1) was observed at various points in time 1. Time is

measured in seconds from the instant of the first observation. The table below gives the results.

Q follows a rule of the form Q(t) = Ae, where A and b are constants.

(a) Use any two of the observations from the table to find the value of A and the value of b,

correct to three decimal places.

(b) Use a different observation from the table to verify your values for A and b.
