Answer:
y= 2x -2
Step-by-step explanation:
........................................
Doing the distance formula for all 4 points only the 1st one is true
We can solve for the value of x using the formula:
V = l w h
where,
h = x the size of the cut since it would form the walls of
the rectangle
<span>w = 8.5 – 2x =
it is subtracted by 2x since two sides will be cut</span>
l = 11 – 2x
Substituting:
V = x (8.5 − 2x) (11 − 2x)
Expanding the expression:
V = 93.5 x – 39 x^2 + 4 x^3
To solve the maxima, we have to get the 1st
derivative dV / dx then equate to 0. dV / dx = 0:
dV / dx = 93.5 – 78 x + 12 x^2
0 = 93.5 – 78 x + 12 x^2
We get:
x ≈ 1.585 in and x ≈ 4.915 in
Therefore Anya’s suggestion of 1.5 inches would create the
larger volume since it is nearer to 1.585 inches.
There can be different volumes since volume refers to the
amount of space inside the rectangle. They can only have similar perimeter and
surface area, but not volume.
It is restricted to <span>0
in. < x < 4.25 in. because our w is 8.5 – 2x. Going beyond that value
will give negative dimensions.</span>
