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 l(t)=t2−t√, and the change in width is given by w(t)=t2−2t12. Which function gives the change in area of the metal strips?

Answer 1

oh your new to this

Answer 2

If you could help me that would be great (:

Answer 3

yea sure i can try

Answer 4

is it multiple choice

Answer 5

yes

a(t)=t4+2t



a(t)=t4+2t+3t52



a(t)=t4−3t52+2t



a(t)=t4+2t−2t12+t√

Answer 6

so what is your idea first
