Y=√x find dy/dx pls show steps

katrin2010 [14]

This involves a quick application of the power rule, which is $f'(x)=nx^{n-1}$ .

First, it is helpful to rewrite $f(x)=\sqrt{x}$ as $f(x)=x^{\frac{1}{2}}$ . Remember that these are equivalent forms, but the latter is easier to use with the power rule.

We apply the power rule and simply:

$\frac{1}{2}(x)^{(\frac{-1}{2})}=\dfrac{1}{2x^{1/2}} = \dfrac{1}{2 \sqrt{x} }$

A board of length 7 divided by the quantity x minus 2 end of quantity meters was cut into two pieces. If one piece is 3 divided

bulgar [2K]

Answer:

Length of other board $=\frac{4x+20}{x^{2} -4}$ metres

Step-by-step explanation:

Given: Length of board = $\frac{7}{x-2}$ metres

Length of board was divided into two.

Length of one piece = $\frac{3}{x+2}$ metres

Let $l$ = length of the other board

Length of the other board = Length of board - Length of one piece

So, $l=\frac{7}{x-2}-\frac{3}{x+2}$

$l=\frac{7(x+2)-3(x-2)}{(x-2)(x+2)} \\\\l=\frac{7x+14-3x+6}{x^{2} -4} \\\\l=\frac{4x+20}{x^{2} -4}$

Thus, length of the other board $=\frac{4x+20}{x^{2} -4}$ metres

How to solve 6x>-24 and 9x<54 ?

djverab [1.8K]

6x>-25 and 9x<54the answer (solve x ) you have 6x>-25 so we solve 'x' we say divide by 6 both side then we get { x>-25/6 or x>-4.166} second you have 9x<54 we say divide by 9 each side { x<6 } your answer is { x>-25/6 and x<6 }
