Why do you think items that come in a larger quantity cost less per unit
MAXImum [283]
They cost less because there are more items in stock meaning that there isn't a limit here is another way of thinking if there are less Items then they can charge you more per item because they know you are gonna want it but if there are tons of that one item they there kinda like eh then you think oh I can live without that.......

Find the interest principle 8000 rate .06 compounded annually years 3
HACTEHA [7]

Answer:

535.07

Step-by-step explanation:

S=P(1+ i) ^n

i= nominal rate of interest / number of compounding periods

i =. 06/12

=0.18

Divided by 100

=0.0018

n- number of times interest is given per year x the number of years

n=12x3

=36

8000(1+0.0018)^36

=8535.07

Interest

8535.07 - 8000

=535.07

Find the derivative of the function f(x) = (x3 - 2x + 1)(x – 3) using the product rule.
julsineya [31]

Answer:

Step-by-step explanation:

Hello, first, let's use the product rule.

Derivative of uv is u'v + u v', so it gives:

f(x)=(x^3-2x+1)(x-3)=u(x) \cdot v(x)\\\\f'(x)=u'(x)v(x)+u(x)v'(x)\\\\ \text{ **** } u(x)=x^3-2x+1 \ \ \ so \ \ \ u'(x)=3x^2-2\\\\\text{ **** } v(x)=x-3 \ \ \ so \ \ \ v'(x)=1\\\\f'(x)=(3x^2-2)(x-3)+(x^3-2x+1)(1)\\\\f'(x)=3x^3-9x^2-2x+6 + x^3-2x+1\\\\\boxed{f'(x)=4x^3-9x^2-4x+7}

Now, we distribute the expression of f(x) and find the derivative afterwards.

f(x)=(x^3-2x+1)(x-3)\\\\=x^4-2x^2+x-3x^3+6x-4\\\\=x^4-3x^3-2x^2+7x-4 \ \ \ so\\ \\\boxed{f'(x)=4x^3-9x^2-4x+7}

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

A newspaper’s cover page is 3/8 text, and photographs fill the rest. If 2/5 of the text is an article about endangered species,
jolli1 [7]

Answer:

\frac{3}{20}

Step-by-step explanation:

Let x be the cover page

We are given that a newspaper 's cover page is \frac{3}{8} text and photograph fill the rest.

We have to find that how much part of cover's page is the article about endangered species

Text =\frac{3}{8}x

Remaining part =x-\frac{3}{8} x

Remaining part =\frac{8x-3x}{8}=\frac{5}{8} x

Therefore, a newspaper;s cover page fill with  Photograph =\frac{5}{8}

If the article about endangered species=\frac{2}{5} of text

Therefore, the article about endangered species=\frac{2}{5}\times\frac{3x}{8}=\frac{3}{20}x

Hence,  the article about endangered species is \frac{3}{20}of the cover page.
