Find the derivative of f(x) = x/6 at x = -2.

AfilCa [17]

$f'(x_0)=\lim\limits_{x\to x_0}\dfrac{f(x)-f(x_0)}{x-x_0}\\\\f(x)=\dfrac{x}{6};\ x_0=-2\\\\subtitute\\\\f'(-2)=\lim\limits_{x\to-2}\dfrac{\frac{x}{6}-\frac{-2}{6}}{x-(-2)}=\lim\limits_{x\to-2}\dfrac{\frac{x}{6}+\frac{2}{6}}{x+2}=\lim\limits_{x\to-2}\dfrac{\frac{x+2}{6}}{x+2}\\\\=\lim\limits_{x\to-2}\left(\dfrac{x+2}{6}\cdot\dfrac{1}{x+2}\right)=\lim\limits_{x\to-2}\dfrac{1}{6}=\dfrac{1}{6}$

The length of a rectangle is 4 cm more than the width and the perimeter is at least 48 cm. What are the smallest possible dimens

Luden [163]

Let w be the width then w+4 is the length and 2*w+2*(w+4)=4*w+8 is the expression for the perimeter. So
4*w+8>=48
4*w>=40
w>=10

angle 1 and angle 2 form a linear pair. If measure angle 1 =18x-1 and measure angle 2=23x+17, find measure angle 2.

finlep [7]

Hey there!
Here's your answer: m<2=114.52 degrees
Here's how I got it: we know that a linear pair of angles is supplementary, aka the sum of the angles is 180 degrees.
you would add 18x-1 and 23x+7 together to equal 180 and solve for x.
then, you would substitute x for 4.24 (rounded) into 23x+17
23(4.24)+17=114.52
Hope this helps!
