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.
Answer:
11 cans
Step-by-step explanation:
Since you know that the ceiling is in the shape of a square and each side is 55ft, you can multiply 55x55 to get 3075, which is divided by 275 due to the amount of paint in a can. It would result in 11 cans, but if it were a decimal like 11.3, then you would need 12 cans since you can't split a can.
