Given:
Rectangular coordinate = (8, 6)
To convert:
Rectangular coordinate to polar coordinate with r > 0 and 0 ≤ θ < 2π.
Solution:
Let us find r:



r = 10
Now, find θ:


Cancel the common factor 2.


θ = 36.87°
The polar coordinates are (r, θ) = (10, 36.87°).
If x is 12 units away from 20 it is either 20-12 or 20+12 so the two possibilities would be 8 or 32

Second step.
To find this, have all the 'ups' as positives and all the 'downs' as negatives, setting up an equation like this:
7 - 3 + 8 - 10 = 2

Answer:
4,000,000
Step-by-step explanation:
There are 1,000 grams in a kilogram
So, multiply 4,000 x 1,000
And you get 4,000,000
