Answer:
Subtract: 5 - 9i = 5-9i
Add: the result of step No. 1 + (-4) = (5-9i) + (-4) = (5-4) + (-9i) = 1-9i
Add: the result of step No. 2 + 7i = (1-9i) + 7i = 1 + (-9+7)i = 1-2i
Subtract: 1 - 2i = 1-2i
Subtract: the result of step No. 1 - 4 = (1-2i) - 4 = (1-4) + (-2i) = -3-2i
Add: the result of step No. 2 + 7i = (-3-2i) + 7i = -3 + (-2+7)i = -3+5i
Step-by-step explanation:
Correct me if I'm wrong pls and ty :).
Hope this helps.
Mean: To find the mean you add all the numbers up and divide by the total number of factors.
12+10+10+13+18+9 = 72
72/6 = 12
Mode: To find the mode, we need to find the number that reoccurs the most in the sequence.
In this case it is 10 because it occurs twice, while the other factors occur once!
Median: To find median we need to arrange the numbers in numerical order. We then cross off one from each side until we come to the middle interger. If it comes between two numbers, you use the half way point between those two numbers.
9 10 10 12 13 18
In this case, we get left with 10 and 12. Meaning that our median is 11!
1. C (2,2)
2. H (-9,-5)
3. B (-2,6)
4. E (8,-4)
5. G (-4,-2)
6. ( 6,8)
7. A (-8,4)
8. F (4,-9)

Step-by-step explanation:
stop using this app, the chances of you actually getting a helpful response or even one at all are so slim, just pay an actual tutor at this point
If you know that 
, then you know right away
###
Otherwise, you can derive the same result. Let 
, so that 
. 
is bounded, so we know 
. For these values of 
, we always have 
.
So, recalling the Pythagorean theorem, we find
Then
as expected.
