**Ashley**, Tuesday, January 29, 2013 at 8:15amOh, sorry I didn't realise that I needed to provide my answer. I just want to check to see if I obtain the correct answer.

My answer is:

P=110i-19i^2

P'=110-38i

0=110-38i

i=2.8947

P"=-38 therefore a max

Max Power in watts = 2.8947

Powermax=put i in the formula for power given, and you have it.
