Homework Help: Calculus

Posted by Anonymous on Wednesday, September 21, 2011 at 8:12pm.

A tree grows 2.80 m during the first year since it was planted. During each subsequent year the tree's growth is 85% of its growth the previous year.

a) Calculate to the nearest 0.001m, the growth of the tree in the fourth year.

Tn = ar^n-1
T4 = 2.80(0.85)^10-1
T4 = 2450
I dont get how to do this, the answer is wrong, its supposed to be 1.72m :\

Determine the first year in which the growth of the tree is less than half a metre.
