Calculate dy/dx when y = (x2 + 2)e 4x as the derivative of a product, letting u = x2 + 2 and v = e4x . Which of the following is

Vera_Pavlovna [14]

Answer:

D. du/dx = 2x

Step-by-step explanation:

Given to find dy/dx where;

$y=(x^{2} +2)e^4^x$

Then when you let;

u=x²+2 and

$v=e^{4x}$

Then

In u=x²+2 du/dx = 2x------------------------step 1

In e^4x, dv/dx = e^4x * d/dx (4x)

=e^4x *4 = 4e^4x------------------------------------step 2

100% = 320
20% = Blue tiles
35% = White Tiles
100% - 55% = Red Tiles = 45%
45% of 320
320 x 0.45 = 144 Red tiles
