Answer:
x = 1
y = -1
Step-by-step explanation:
A*B= (4y-8 3x-3)
1-) (4×2)+(3×y)= 3y+8
2-) (4×x)+(3×(-1))= 4x-3
AB=C
(3y+8 4x-3)=(5 1)
So
3y+8=5 ; y= -3/3 = -1
4x-3=1 ; x=4/4 =1
Th long side of the plastic sheet is bent into a U shape.
Therefore the dimensions of the file holder are 8, h, and (10 - 2h) as shown in the figure.
The volume of the file holder is
V = 8*h*(10 - 2h) = 80h - 16h²
To maximize V, V'(h) = 0.
That is,
80 - 32 h = 0
h = 80/32 = 2.5 in
V''(h) = -32 guarantees that V is maximum because V'' <0.
Maximum V = 80*(2.5) - 16*(2.5)² = 100 in³
Answer: h = 2.5 in
