Find the derivative of f(x) = negative 5 divided by x at x = 11.

Yuki888 [10]

I want to believe the equation is,
f(x) = -5/x
This can be written as;

f(x) = y

y = -5 x⁻¹
derivative = dy/dx = (-1)(-5)x(⁻1-1)
= 5x⁻²

Derivative at x=11,

dy/dx = 5(11)⁻²
= 5/(11²)
= 5/121

So, the derivative of f(x) = -5/x at x=11 is 5/121.

jeka57 [31]

$\bf _nP_r=\cfrac{n!}{(n-r)!}\qquad \qquad \qquad _{18}P_4=\cfrac{18!}{(18-4)!}$

one may note that, your calculator besides having a [ ! ] factorial button, it also has a [ ₙPᵣ ] button for permutations, and you can use that too.

$12 to $6 percent change

Vesna [10]

To figure out any percent change, you find the difference between the two numbers, and then divide that difference by the original number. So 12-6=6, 6/12=0.5, so a 50% change.
