An automated trading algorithm is monitoring the growth of a digital asset portfolio. The value of the portfolio, VVV pounds, at time ttt weeks after the algorithm was activated is modelled by the equation
log10V=1.94+0.12t\log_{10} V = 1.94 + 0.12tlog10V=1.94+0.12t
Write this equation in the form V=abtV = ab^tV=abt, where aaa and bbb are constants to be found. Give each value to 4 significant figures.
When t=Tt = Tt=T, the value of the portfolio is £4000. Find the value of TTT according to the model, giving your answer to 3 significant figures.
The algorithm is programmed to trigger a 'rebalance' alert if the portfolio value exceeds £5000. Determine whether or not the portfolio will require a rebalance within the first 14 weeks.
