A new social media platform, ‘ConnectU’, is experiencing rapid growth in its user base. The platform’s administrators are modelling the user growth to predict future server capacity needs and plan marketing strategies.
a. Initially, the number of users, $N$, can be modelled by an exponential function $N(t) = A e^{kt}$, where $t$ is the time in weeks since the platform launched, and $A$ and $k$ are constants. At launch ($t=0$), ConnectU had 500 users. After 4 weeks, the platform had 3000 users. Find the values of $A$ and $k$ (correct to four decimal places).
