Given:
The number is 
.
To find:
The a+bi form of given number.
Solution:
We have,
It can be written as
![[\because \sqrt{ab}=\sqrt{a}\sqrt{b}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csqrt%7Bab%7D%3D%5Csqrt%7Ba%7D%5Csqrt%7Bb%7D%5D)
![[\because \sqrt{-1}=i]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csqrt%7B-1%7D%3Di%5D)
Here, real part is missing. So, it can be taken as 0.
So, a = 0 and 
.
Therefore, the a+bi form of given number is 
.
Answer:
complementary angles, x=19
Step-by-step explanation:
since the two parts of the angle add up to 90, they are complementary angles.
you can find x by adding them and setting it equal to 90:
3x-2+2x-3 = 90
5x-5 = 90
5x = 95
x = 19
370
expalnation
subtract 18 from 55 and get 37
then times by 10
The Solution:

Substitute:
Take the square root of both sides:
Answer:
9 inches
Answer:
gradient = -5
Step-by-step explanation:
A line passes (x1, y1) and (x2, y2) has the gradient (slope) which is calculated by:
gradient = (y2-y1)/(x2-x1)
As shown in picture, this blue line passes (-1, 0) and (0, -5)
=> gradient = (-5 - 0)/(0 - -1) = -5/1 = -5
Hope this helps!
