Multiply 4.6 x 2/7 round the answer to the nearest hundredth

Answers

type into the calculator:
4.6*(2/7)
the calculator answer is 1.31428...
we want to round to the nearest hundredth. the hundredths place is in bold: 1.31428
to round, we look at the number to the right of the hundredths place, which is underlined:
1.31428
if the number on the right is 5 or greater, we add 1 to the number to the left. if the number on the right is 4 or less, then we leave the number on the left alone.
the number on the right here is 4, so we leave the number on the left alone, leaving us with 1.31

well I converted 2/7 to its decimal which is 0.285714286
then did 4.6x0.285714286 and got 1.314285716

Which of the following is a solution of z^5 = 1 + √3 i? 5√2 (cos150° + isin150°)
5√2 (cos156° + isin156°)
5√2 (cos174° + isin174°)
5√2 (cos204° + isin204°)

Please show me how to work it out.

Answers

Answer:

Option 2 is right

Step-by-step explanation:

Given that

$z^5=1+√(3) i$

We can write this in polar form with modulus and radius

$|z^5|= √(1+3) =2\ntan of Angle t =√(3) \n$

Hence angle = 60 degrees and

$|z^5|= 2(cos60+isin60)$

Since we have got 5 roots for z, we can write 60, 420, 780, etc. with periods of 360

Using Demoivre theorem we get 5th root would be

5th root of 2 multiplied by 1/5 th of 60, 420, 780,....

$z= \sqrt[5]{2} (cos12+isin12)\nz=\sqrt[5]{2} (cos84+isin84)\n\nz=\sqrt[5]{2} (cos156+isin156)\n\nz=\sqrt[5]{2} (cos228+isin228)\n\nz=\sqrt[5]{2} (cos300+isin300)\n$

Out of these only 2nd option suits our answer

Hence answer is Option 2.
