**The second derivative at the point (2,2) is 34/9**

<u>**Explanation:**</u>

<u></u>

2x⁴ = 4y³

2x⁴ - 4y³ = 0

We first need to find dy/dx and then d²y/dx²

On differentiating the equation in terms of x

dy/dx = d(2x⁴ - 4y³) / dx

We get,

dy/dx = 2x³/3y²

On differentiating dy/dx we get,

d²y/dx² = 2x²/y² + 8x⁶/9y⁵

d²y/dx² = 34/9

**Therefore, the second derivative at the point (2,2) is 34/9**

**Answer:**

Amount of VAT paid by Jeremy is € 9.31 .

**Step-by-step explanation:**

As given

In Germany, VAT is at 19% .

Jeremy buys a calculator in Germany for €58.31

This price includes VAT.

Let us assume that the cost of calculator excluding tax is x .

19% is written in the decimal form .

= 0.19

VAT Price = 0.19 × Cost price of calculator excluding VAT

= 0.19 × x

= 0.19x

Than

Cost of calaculator + VAT price = Cost of calculator including VAT

x + 0.19 × x = 58.31

x + 0.19x = 58.31

1.19x = 58.31

x = €49 (Approx)

Thus cost price of calculator excluding VAT is €49 .

VAT Price = 0.19 × Cost price of calculator excluding VAT

= 0.19 × 49

= € 9.31

Therefore the amount of VAT paid by Jeremy is € 9.31 .
