Find f'(x) and simplify!

Ede4ka [16]

$\bf f(x)=\cfrac{sin(x)}{x^2}\implies \cfrac{dy}{dx}=\cfrac{x^2cos(x)-2xsin(x)}{(x^2)^2}
\\\\\\
\cfrac{dy}{dx}=\cfrac{x[xcos(x)-2sin(x)]}{x^4}\implies \cfrac{dy}{dx}=\cfrac{xcos(x)-2sin(x)}{x^3}
\\\\
-----------------------------\\\\$

$\bf f(x)=(3x^2+2x-1)^4\implies \cfrac{dy}{dx}=4(3x^2+2x-1)^3(6x+2)
\\\\
-----------------------------\\\\
f(x)=\left( \cfrac{x-5}{2x+1} \right)^2\implies \cfrac{dy}{dx}=2\left( \cfrac{x-5}{2x+1} \right)\left[ \cfrac{2x+1-2(x-5)}{(2x-1)^2} \right]
\\\\\\
\cfrac{dy}{dx}=2\left( \cfrac{x-5}{2x+1} \right)\left[ \cfrac{11}{(2x-1)^2} \right]$

In this problem, we have these following percentages.

35% of the customers select the basic camera.

This also means that:

65% of the customers select the deluxe version. (Since you can buy only two versions of the hard disk camera and the sum of the percentages is 100%).

20% of those who select the basic camera also purchase the extended warranty.
