If y= 1-x+x²/1+x-x² than how about y'=? <br> This question is about derived function.

zavuch27 [327]

Answer:

$\frac{d}{dx}\left(1-x+\frac{x^2}{1}+x-x^2\right)=0$

$y'=0$

Step-by-step explanation:

Given the function

$y=\:1-x+\frac{x^2}{1}+x-x^2$

Taking derivative

$\frac{d}{dx}\left(1-x+\frac{x^2}{1}+x-x^2\right)$

$\mathrm{Apply\:the\:Sum/Difference\:Rule}:\quad \left(f\pm g\right)'=f\:'\pm g'$

$=\frac{d}{dx}\left(1\right)-\frac{d}{dx}\left(x\right)+\frac{d}{dx}\left(\frac{x^2}{1}\right)+\frac{d}{dx}\left(x\right)-\frac{d}{dx}\left(x^2\right)$

$\frac{d}{dx}\left(1\right)=0$ ∵ $\mathrm{Derivative\:of\:a\:constant}:\quad \frac{d}{dx}\left(a\right)=0$

$\frac{d}{dx}\left(x\right)=1$ ∵ $\mathrm{Apply\:the\:common\:derivative}:\quad \frac{d}{dx}\left(x\right)=1$

$\frac{d}{dx}\left(\frac{x^2}{1}\right)=2x$ ∵ $\mathrm{Apply\:the\:Power\:Rule}:\quad \frac{d}{dx}\left(x^a\right)=a\cdot x^{a-1}$

$\frac{d}{dx}\left(x\right)=1$ ∵ $\mathrm{Apply\:the\:common\:derivative}:\quad \frac{d}{dx}\left(x\right)=1$

$\frac{d}{dx}\left(\frac{x^2}{1}\right)=2x$ ∵ $\mathrm{Apply\:the\:Power\:Rule}:\quad \frac{d}{dx}\left(x^a\right)=a\cdot x^{a-1}$

substituting all the values in the expression

$=\frac{d}{dx}\left(1\right)-\frac{d}{dx}\left(x\right)+\frac{d}{dx}\left(\frac{x^2}{1}\right)+\frac{d}{dx}\left(x\right)-\frac{d}{dx}\left(x^2\right)$

$=0-1+2x+1-2x$

$=0$

Hence,

$\frac{d}{dx}\left(1-x+\frac{x^2}{1}+x-x^2\right)=0$

Therefore,

$y'=0$

If point F is the midpoint of segment DE, which statement is true?

FinnZ [79.3K]

Segment DF is 1/2 the length of Segment DE. Since the entire segment is DE and it's midpoint is at F, the segment would be broken into 2 equal segments in one. Segment DF and FE. Segment DF is congruent to Segment FE.

How many three-digit numbers can you make if you are not allowed to use any other digits except 4 and 0?

kozerog [31]

Answer:

There is a slight problem with this question

Do numbers starting with "0" count as a digit position

I would say no, thus the answer is 4...

if you are allowed to use 0 then the answer is 8

in other words if the question was using only 4's and 1's then the answer would be 8
