<h3>Function Notation</h3>
The function is given as:

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:

Evaluate the exponent

Expand the bracket

So, the correct work is:

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
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 = 3200 * 100
Original price = £320000
