Find [4(cos15° + isin15°)]^3 and express it in a + bi form.
AleksandrR [38]

Answer:

see explanation

Step-by-step explanation:

Using De Moivre's theorem

Given

[ 4(cos15° + isin15° ) ]³, then

= 4³ [ cos(3 × 15°) + isin(3 × 15°) ]

= 64 (cos45° + isin45° )

= 64 (\frac{\sqrt{2} }{2} + \frac{\sqrt{2} }{2} i )

= 64 (\frac{\sqrt{2} }{2} (1 + i) )

= 32\sqrt{2} (1 + i)

= 32\sqrt{2} + 32\sqrt{2} i

Rate and Ratios IF 3 kg of potatoes cost R24. How much will 7 kg of potatoes cost ​
balu736 [363]

Answer:

7kg of potatoes cost 56 R (dollars)

Step-by-step explanation:

First, we have to find the unit price of 1kg of potatoes. To do this we divide <em>24 by 3</em>. That's <em>8</em>. Each kg of potato costs 8 dollars.

Now, all we have to do is multiply <u><em>8 by 7</em></u>.

8 is the unit rate/kg and 7kg is the amount they are asking.

<u><em>8x7=56</em></u>

7kg of potatoes cost 56R
