TopicExponential Equations & Modelling

  1. The value, \(\pounds V\), of a vintage car \(t\) years after it was first valued on 1 st January 2001, is modelled by the equation
$$V = A p ^ { t } \quad \text { where } A \text { and } p \text { are constants }$$ Given that the value of the car was \(\pounds 32000\) on 1st January 2005 and \(\pounds 50000\) on 1st January 2012
    1. find \(p\) to 4 decimal places,
    2. show that \(A\) is approximately 24800
  1. With reference to the model, interpret
    1. the value of the constant \(A\),
    2. the value of the constant \(p\). Using the model,
  2. find the year during which the value of the car first exceeds \(\pounds 100000\)
