Remember PEMDAS ? The order of operation: Find the sqt of 2 and then raise that value to the 3rd power to get 2.828...

It wants to know the value of that operation to the nearest tenth place, the first value after the decimal. It is called tenth because the value is 1/10 of a whole (1). So 2.8

\displaysyle (\sqrt 2)^{3}=(2^{\frac{1}{2}})^3=2^{\frac{1}{2} \cdot 3}=2^{\frac{3}{2}}=\sqrt {2^3}=\sqrt 8

√8 is between 2 and 3, because 2²=4<8, but 3²=9>8. Also, our value is closer to 3 than to 2, so it is more than 2.5 and we have C and D options left.

Among these two numbers we find the one which is closer to √8.

C. 27=√729 ⇒ 2.7=√7.29

D. 28=√784 ⇒ <u>2.8=√7.84</u>

Hence our answer is D) 2.8

How does this work?????

Answer:

x = 4\sqrt{5}

Step-by-step explanation:

Since the triangle is right, solve for x using Pythagoras' identity, that is

x² = 8² + 4² = 64 + 16 = 80

Take the square root of both sides

x = \sqrt{80} = \sqrt{16(5)} = \sqrt{16} × \sqrt{5} = 4\sqrt{5} ← exact value

Fernando purchased a new motorhome for $180,000, but the motorhome will depreciate
Dmitry_Shevchenko [17]

Your answer would be 122,400.

<em>To solve, follow these steps!! </em>First let's start with the price of the motorhome, 180,000. If it <em>depreciates, </em>that means it's going to lose value ever year.

It will depreciate 4% every year, so we need to find 4% of 180,000. You can just plug this into a calculator and get 7,200.

Next, it will depreciate for 8 years, so we multiply 7,200 x 8 and get 57,600. Lastly, we will subtract this from 180,000 and get 122,400.
