Answer:
C. 4x^3 - 14x^2y + 14xy^2 - 4y^3
Step-by-step explanation:
Given:
Product of 2x^2 – 3xy + y^2 and 2x – 4y
Product means multiplication
(2x^2 – 3xy + y^2) (2x – 4y)
Open the bracket
= 4x^3 - 8x^2y - 6x^2y + 12xy^2 + 2xy^2 - 4y^3
Simplify the like terms
= 4x^3 - 14x^2y + 14xy^2 - 4y^3
The answer is
C. 4x^3 - 14x^2y + 14xy^2 - 4y^3

Answer:
$49.5
Step-by-step explanation:
y = -x^2 + 99x - 932
The maximum point is :
dy/dx = 0
Take the first derivative of y
dy/dx = - 2x + 99
Put - 2x + 99 = 0
-2x = - 99
x = 99 / 2
x = 49.5
Hence, To make maximum profit, widget should be sold at $49.5 per widget.
