The function A(w)= -2w^2+ 576 models the area of a pasture enclosed by a rectangular fence,where w is width in metres.
A. What is the maximum area that can be enclosed?
B. Determine the area that can be enclosed using a width of 20m
C. Determine the width of the rectangular pasture that has an area of 18,144m^2
A) 'w' cannot be negative , so the largest area will occur when w = 0 526 m^2 (which is kinda comical having a w = 0 )
Are you sure you have the equation written correctly ???? Please proofread ....because none of these answers make sense!
B) -2 (202) + 576 = _____________ (nonsensical answer)
C) 18 144 = - 2 w2 + 576 (another nonsensical answer)
