How to find the derivative of the below question?
​

Answers

Given:

[tex]y=\dfrac{x}{\sqrt{x-1}}[/tex]

To find:

The derivative of the given problem.

Solution:

Chain rule : [tex]\dfrac{d}{dx}f(g(x))=f'(g(x))\cdot g'(x)[/tex]

Quotient rule : [tex]\dfrac{d}{dx}\left(\dfrac{f(x)}{g(x)}\right)=\dfrac{g(x)f'(x)-f(x)g'(x)}{[g(x)]^2}[/tex]

We have,

[tex]y=\dfrac{x}{\sqrt{x-1}}[/tex]

Differentiating with respect to x using chain rule and quotient rule, we get

[tex]\dfrac{dy}{dx}=\dfrac{\sqrt{x-1}\dfrac{d}{dx}(x)-x\dfrac{d}{dx}(\sqrt{x-1})}{(\sqrt{x-1})^2}[/tex]

[tex]\dfrac{dy}{dx}=\dfrac{\sqrt{x-1}(1)-x\dfrac{1}{2\sqrt{x-1}}\dfrac{d}{dx}(x-1)}{(x-1)}[/tex]

[tex]\dfrac{dy}{dx}=\dfrac{\sqrt{x-1}-\dfrac{x}{2\sqrt{x-1}}(1-0)}{x-1}[/tex]

[tex]\dfrac{dy}{dx}=\dfrac{\sqrt{x-1}-\dfrac{x}{2\sqrt{x-1}}}{x-1}[/tex]

[tex]\dfrac{dy}{dx}=\dfrac{\dfrac{2x-2-x}{2(x-1)^{\frac{1}{2}}}}{(x-1)}[/tex]

[tex]\dfrac{dy}{dx}=\dfrac{x-2}{2(x-1)^{\frac{3}{2}}}[/tex]

Therefore, the required derivative is [tex]\dfrac{dy}{dx}=\dfrac{x-2}{2(x-1)^{\frac{3}{2}}}[/tex].

8(3x-2)=2(8)+16 explanation how the order of operations is used. How the equation is kept balanced.

Answers

Answer:

See explanation

Step-by-step explanation:

Given;

8(3x-2)=2(8)+16

We clear the brackets

24x - 16 = 16 + 16

24x - 16 = 32

We add 16 to both sides

24x - 16 + 16= 32 + 16

24x = 48

We divide both sides by 24

24x/24 = 48/24

x =2

Find the slope of the line that passes through (2, 12) and (9, 3).
Simplify your answer and write
as a proper fraction, improper fraction, or integer.

Answers

Answer:

The slope of line is [tex]-\frac{9}{7}[/tex].

Step-by-step explanation:

Given points are;

(2, 12) and (9, 3)

Here,

x1 = 2 and y1 = 12

x2 = 9 and y2 = 3

Slope of a line is given by the following formula;

[tex]m =\frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{3-12}{9-2}\\\\m=\frac{-9}{7}[/tex]

Therefore,

The slope of line is [tex]-\frac{9}{7}[/tex].
