Answer:
The slope would flip along with the sign so it would be 2x
Answer:
225 square meters
Step-by-step explanation:
Area of a square:
A = w², where w is the width of the square
Plug in values:
A = 15m²
A = 225 square meters
(x − 8)(y − 4) = 50, so y = 4 + 50
x−8
. Then
A(x) = x
4 + 50
x − 8
x > 8.
A
0
(x) = 4 −
400
(x − 8)2
, so A
0
(x) = 0 gives x = 18.
A
00(x) = 800
(x − 8)3
> 0
so the function is concave up, so x = 18 is the absolute minimum. When x = 18, y = 9.
