B/a = (3 - 2i)/(2 + i)
To divide complex numbers, you multiply the numerator and denominator by the complex conjugate of the denominator.
The complex conjugate is 2 - i. ** Remember i^2 = -1 **a + bi
( 3 - 2i) ( 2 - i)
------------------- Foil numerator and denominator.
(2 + i) ( 2 - i)
6 - 3i - 4i + 2i^2 6 - 7i - 2 4 - 7i 4 - 7i
--------------------- ----------- ------- OR --- -----
4 - i^2 4 + 1 5 5 5
The answer can be written either way. If they specify real part and imaginary part, the second option is correct.
Two angles adjacent angles that add up to 180 degrees
Know a are:
CW=75. SL= 250. Y= 2x
CW= X= number of wings
SL= Y= number of sliders
X+Y= Total number of items, which can be rewritten as X+2X= total
Plug in the calories for the total
2(75X) +250X= 800
150x+250X= 400X= 800
X= 800/400=2 pieces of Slider
Double the amount for Wings=2x2=4
4wings/2 Sliders
The answer is D i believe
