Answer:
Step-by-step explanation:
Complex numbers are the numbers represented by the expression = a + bi
Here a = real part of the number
bi = imaginary part
a and b are the real numbers.
[Since, 
]
Therefore, its a non real complex number.
2 - 
= 
= 
= 
This number is a Non real complex number.
= 18i
It's a non real complex number.
3 + 2i
It's a non real complex number.
-289
It's a purely real number.
= 4 + 32
= 36
It's a purely real number.
Answer:
42 yards
Step-by-step explanation
There are 4 sides to a rectangle. 2 lengths, and 2 widths. That means that you multiply both values by 2 and then add them together, so 40 + 2. A more basic way to think of it is 20+20+1+1. Therefore, the perimeter is 41 yards.
Step-by-step explanation:
just count off the positions after the decimal point.
they go with decreasing negative exponents of ten.
the first position is 1/10.
the second 1/100.
the third 1/1000.
the fourth 1/10000
the fifth 1/100000
and that is how we can easily convert such decimals into fractions.
0.63333 = 63333 / 100000
or were you looking for the infinite decimal ?
that would be 1.9/3 = 19/10 / 3 = 19/30
I found this by simply suspecting that there is a division by 3 involved (due to the 3333333 repeating pattern).
so, by multiplying 0.63333 by 3 we get 1.9.
1.9 = 19/10
and then dividing by 3 gives us 19/30
