a repeating decimal is placed over 9's instead of 0's. for example: 0.23 = , but 0.232323... =
a) x = 0.121212
b) 100(x) = 100(0.121212)
100x = 12.1212
c) 100x = 12.1212
- <u> x = 0.1212</u>
99x = 12
x =
d) -2 <em>= -2
when simplified</em>
The number is rational becase it has a repeating decimal
Answer:
your answer will be<u> A.85°</u>
Step-by-step explanation:

have a great day!!!
Let the given complex number
z = x + ix =
We have to find the standard form of complex number.
Solution:
∴ x + iy =
Rationalising numerator part of complex number, we get
x + iy =
⇒ x + iy =
Using the algebraic identity:
(a + b)(a - b) = -
⇒ x + iy =
⇒ x + iy = [ ∵
]
⇒ x + iy =
⇒ x + iy =
⇒ x + iy =
⇒ x + iy = 1 - i
Thus, the given complex number in standard form as "1 - i".
