Answer:

b = 11 m

l = 44 m

Step-by-step explanation:

l = 4b (length is four times width)

Perimeter = 110 m

2 * ( l + b ) = 110

2 * (4b + b ) = 110

2 * 5b = 110

b = 110 / ( 2*5) = 11

b = 11 m

l = 4b = 4 * 11 = 44 m

How do you differentiate #f(x)=x / cot (x) + 3# using the quotient rule?

Rzqust [24]

I'm assuming

$f(x)=\dfrac x{\cot x+3}$

By the quotient rule, the derivative $f'(x)$ is

$\dfrac{(\cot x+3)(x)'-x(\cot x+3)'}{(\cot x+3)^2}=\dfrac{(\cot x+3)(1)-x(-\csc^2x)}{(\cot x+3)^2}=\dfrac{x\csc^2x+\cot x+3}{(\cot x+3)^2}$
