Answer:
third option
Step-by-step explanation:
Using De Moivre's theorem
( + i)³ , then
| + i |
=
= = = 2
arg( + i) = ( ) =
Thus
( + i)³
= 2³ [ cos(3 × ) + isin( 3 × ) ]
= 8 [ cos() + isin( ) ]
Answer:
-23/4
Step-by-step explanation:
add everything in the ()
your'e left then with -1/2(11/2)-3
then multiply
and get -11/4-3
when you subtract you are left with -23/4
Naomi has 43 red beads. 7 white beads times 6 equals 42. 42 plus 1 equals 43. Sometimes you just need to guess and check using common sense. Otherwise an equation would be x+(6x+1)=50, which would be 7x+1+50. Then you simplify to 7x=49 and get x=7. Then multiply by 6 and add 1 to get 43
