It’s should be -30 instead of 30 so the answer would be y= -3
Answer:
37/50
Step-by-step explanation:
because 37% is out of 100
First, find the actual difference / spread between the buy and sell rates:
$0.7714 - $0.7621 = $0.0093.
To find the percentage, we need to divide either given amount ($0.7621 or $0.7714) and to multiply the result by 100%:
($0.0093 / $0.7714) * 100% = 1.21%
◆ COMPLEX NUMBERS ◆
125 ( cos 288 + i sin 288 ) can be written as -
125.e^i( 288)
125.e^i( 288 +360 )
125.e^i( 288+ 720)
[ As , multiples of 360 can be added to an angle without changing any trigonometric functions or sign ]
To find the cube root , take the cube root of above 3 expressions ,
We get -
5 e^( i 96 )
5 e^( i 216 )
5 e^( i 336 )
Now using Euler's formula , We rewrite above as -
5 ( cos 96 + i sin 96 )
5(c os 216 + i sin 216 )
5 ( cos 336 + i sin 336 ) Ans.
