What is the derivative of Y=2x^3-2x^2-3x+1 with respect to x?

umka2103 [35]

$~~~~~~~~~y= 2x^3 -2x^2 -3x+1\\\\\\\implies \dfrac{dy}{dx} =\dfrac d{dx} \left( 2x^3 -2x^2 -3x +1\right)\\\\\\~~~~~~~~~~~=2 \dfrac{d}{dx}\left(x^3\right) - 2 \dfrac d{dx} \left(x^2\right) - 3 \dfrac d{dx} (x) +\dfrac{d}{dx}(1)\\ \\\\~~~~~~~~~~~=2\cdot 3x^2 -2\cdot 2x-3 +0~~~~~~~;\left [ \dfrac d{dx} x^n = nx^{n-1}\right]\\\\\\~~~~~~~~~~~=6x^2 -4x -3$

$\text{The derivative is}~6x^2 -4x -3$

The box plot below shows the total amount of time, in minutes, the students of a class surf the Internet every day:

pashok25 [27]

The information that provided by the graph are median and the range. The information that cannot be gotten from the graph is the mode.

The interquartile range is 25.

The outlier would distort the value of the median and mean.

<h3>How can a box plot be interpreted?</h3>

The information that can be derived from the box plot are the minimum value, maximum value, range, median, first quartile and third quartile.

The interquartile range is the difference between the first quartile and third quartile.

Interquartile range = 60 - 35 = 25

Danny, Pedro, Derick, Jose, and Willy went to a soccer game. They each got a $3-off coupon to buy themselves a ticket to the gam

kondor19780726 [428]

I think it’s 22.4
the total is 37 then divided by 5 for each person. after you divide you add the $3 coupon so for each person would be 3 by 5 to equal 15. so 37 divided by 5 is 7.4 and then add 15 to get 22.4. If this is wrong please correct me :)

Answer:

$\large\boxed{D.\ x+4}$

Step-by-step explanation:

$\dfrac{x^2-16}{x-4}\\\\\text{use}\ a^2-b^2=(a-b)(a+b)\\\\=\dfrac{x^2-4^2}{x-4}=\dfrac{(x-4)(x+4)}{x-4}\\\\\text{canceled}\ (x-4)\\\\=\dfrac{x+4}{1}=x+4$
