Question

A machine is set up to cut metal strips of varying lengths and widths based on the time (t) in minutes. The change in length is given by the function I(t)=t^2-squrt(t),, and the change in width is given by w(t)=t^2-2t^1/2. Which function gives the change in area of the metal strips?

Answer 1

Mhm no answer choices?

Answer 2

I think the answer is a(t) = t^4 - 3t^(5/2) + 2t`

Answer 3

thank you so much!! i really appreciate the help!
