The correct works are:

$Blue(s + h) = 2s^2 + 4sh + 2h^2 + 3$ .
$\frac{Blue(s + h) - Blue(s)}{h} = 4s + 2h$

<h3>Function Notation</h3>

The function is given as:

$Blue(s) = 2s^2 + 3$

The interpretation when Steven is asked to calculate Blue(s + h) is that:

Steven is asked to find the output of the function Blue, when the input is s + h

So, we have:

$Blue(s + h) = 2(s + h)^2 + 3$

Evaluate the exponent

$Blue(s + h) = 2(s^2 + 2sh + h^2) + 3$

Expand the bracket

$Blue(s + h) = 2s^2 + 4sh + 2h^2 + 3$

So, the correct work is:

$Blue(s + h) = 2s^2 + 4sh + 2h^2 + 3$

<h3>Simplifying Difference Quotient</h3>

In (a), we have:

$Blue(s + h) = 2s^2 + 4sh + 2h^2 + 3$

$Blue(s) = 2s^2 + 3$

The difference quotient is represented as:

$\frac{f(x + h) - f(x)}{h}$

So, we have:

$\frac{Blue(s + h) - Blue(s)}{h} = \frac{2s^2 + 4sh + 2h^2 + 3 - 2s^2 - 3}{h}$

Evaluate the like terms

$\frac{Blue(s + h) - Blue(s)}{h} = \frac{4sh + 2h^2}{h}$

Evaluate the quotient

$\frac{Blue(s + h) - Blue(s)}{h} = 4s + 2h$

Hence, the correct work is:

$\frac{Blue(s + h) - Blue(s)}{h} = 4s + 2h$

Given the roll of paper towels below how much plastic would be needed to cover the role so it can be sold given the diameter of

gladu [14]

Answer:

Amount of plastic need to cover paper role = 565.2 inches

Step-by-step explanation:

Given:

Diameter of paper role = 10 inch

Height of paper role = 13 inch

Find:

Amount of plastic need to cover paper role

Computation:

Radius of paper role = Diameter of paper role / 2

Radius of paper role = 10 / 2

Radius of paper role = 5 inch

Amount of plastic need to cover paper role = Total surface area of cylinder

Amount of plastic need to cover paper role = 2πr(h+r)

Amount of plastic need to cover paper role = 2(3.14)(5)(13+5)

Amount of plastic need to cover paper role = (3.14)(10)(18)

Amount of plastic need to cover paper role = 565.2 inches

PLEASE HELP PLEASE THANK U SO MUCH

arlik [135]

Answer:

Step-by-step explanation:

x² - 7x - 18 = 0

Product = -18

Sum = -7

Factors = 2 , (-9) {2*(-9) = -18 & 2 +(-9) = -7}

x² + 2x - 9x - 18 = 0

x(x + 2) - 9(x + 2) = 0

(x +2)(x - 9)= 0

x + 2 = 0 ; x - 9 = 0

x = -2 ; x = 9

x = -2 , 9

Sale price = 272000

Reduction percentage = 15%

Let the original price = x

Reduction = 15% of x

Original price - reduction price = Sale price

x - 15% of x = £272000

$x -\dfrac{15}{100}x = 272000\\\\\\\dfrac{100}{100}x-\dfrac{15}{100}x=272000\\\\\\\dfrac{85}{100}x=272000\\\\\\x=272000*\dfrac{100}{85}$

x = 3200 * 100

Original price = £320000
