Answer:
-6x² -6xh -2h²
Step-by-step explanation:
Apparently, you want ...
(f(x+h) -f(x))/h
for f(x) = 14 -2x³
That difference quotient is ...
![\dfrac{f(x+h)-f(x)}{h}=\dfrac{(14 -2(x+h)^3)-(14-2x^3)}{h}\\\\ =\dfrac{14-2(x^2 +3x^2h+3xh^2+h^3)-14+2x^3}{h}=\dfrac{-6x^2h-6xh^2-2h^3}{h}\\\\ =\boxed{-6x^2 -6xh-2h^2}](https://tex.z-dn.net/?f=%5Cdfrac%7Bf%28x%2Bh%29-f%28x%29%7D%7Bh%7D%3D%5Cdfrac%7B%2814%20-2%28x%2Bh%29%5E3%29-%2814-2x%5E3%29%7D%7Bh%7D%5C%5C%5C%5C%20%3D%5Cdfrac%7B14-2%28x%5E2%20%2B3x%5E2h%2B3xh%5E2%2Bh%5E3%29-14%2B2x%5E3%7D%7Bh%7D%3D%5Cdfrac%7B-6x%5E2h-6xh%5E2-2h%5E3%7D%7Bh%7D%5C%5C%5C%5C%20%3D%5Cboxed%7B-6x%5E2%20-6xh-2h%5E2%7D)
The difference is "You have to pay interest on credit cards but not on charge cards" , Option B
<h3>What are Credit Cards ?</h3>
The cards is a financial tool generally issued by banks which let you to borrow money for expenses and make payments afterward in installments.
Credit cards and charge cards differ in two important ways. One is the method of payment
The other difference is
You have to pay interest on credit cards but not on charge cards, as in credit card the person gets lot of time for the payment and the payment can be made in installments and so for this facility extra charge in terms of interest.
Therefore Option b is the correct answer.

Answer:
The height of deepness of submarine is 424.1 feet
Step-by-step explanation:
Given as :
The angle at which submarine drives of the surface of water = Ф = 13°
The speed at which submarine travel = s = 760 feet per minute
Let The height of deepness of submarine = h feet
The time taken to reach that deepness = t = 5 minutes
<u>According to question</u>
The height of deepness of submarine = ![\dfrac{\textrm speed}{\textrm time}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctextrm%20speed%7D%7B%5Ctextrm%20time%7D)
i.e h × cos(90 - Ф) = ![\dfrac{s}{t}](https://tex.z-dn.net/?f=%5Cdfrac%7Bs%7D%7Bt%7D)
Or, h × Sin(Ф) = ![\dfrac{\textrm 760 feet per min}{8 min}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctextrm%20760%20feet%20per%20min%7D%7B8%20min%7D)
Or, h × Sin(13°) = 95 feet
Or, h × 0.224 = 95 feet
∴ h = ![\dfrac{95}{0.224}](https://tex.z-dn.net/?f=%5Cdfrac%7B95%7D%7B0.224%7D)
i.e h = 424.10 feet
So, The height of deepness of submarine = h = 424.10 feet
Hence, The height of deepness of submarine is 424.1 feet Answer
