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".
Answer: 4.25
divide 4 on both sides, and it should leave you with x = 4.25
your welcome :)
Answer:
A series of translations to map at least two angles of the image to two angles of the pre-image.
Step-by-step explanation:
we have 2 figures: △ABC and △A′B′C′
△A′B′C′ is the dialation of △ABC
we have to prove that the figures are similar using AA similarity
AA = (Angle-Angle)
Option D is correct.
Answer:
8.5 min
Step-by-step explanation:
Here, distance = rate times time. The rate is 10 in/min, and so
d = (10 in/min)t.
If the snail travels 85 in, then 85 in = (10 in/min)t, and we solve for t as follows:
t = (85 in) / (10 in/min) = 8.5 min
Answer: 25
Step-by-step explanation: I just entered the equation into my calculator like so.
A negative number times a negative number equals a positive number.
I hope this helps, have a nice day.
