I just wanted to make sure I'm on the right path with this question:

1. A plane takes off from an airport which is at sea level. The aircraft's altitude in metres at a time of t minutes is modelled by the equation h = 5400 In(t + 1) a) What is the height of the plane after five minutes? If we consider E= 5 then m = metres h = 5400 in (5+ 1 ) = 5400 La (6) = 5400 x 1. 79 1 75 9469 = 9675. 50m (to 2 d. p. )
