A. Like charges repel each other. Just think opposites attract for charged particles.
Answer:
43rd term
Step-by-step explanation:
Arithmetic sequences are basically linear functions, so the same value is added every time. So, knowing that Asub1 is equal to one, and Asubn is equal to 169 we can take 169-1 and divide by our common difference. This is four as 5-1=4 and 9-5=4.
So, (169-1)/4=42.
This is however 42 terms after Asub1, so this would be the 43rd teen of the sequence!
You can use the cosine rule for this - you might have to change some of the letters around for it to make sense though. Hope this helps!
Answer:
10 and 7
Step-by-step explanation:
First you can list out numbers 1-10 and find thngs that equal 3 when subtracted. Then after you do that see if when you multiply y x 3 subtracted from x if it equals -11.
10-7 =3
10 - (7x3)
10 - 21
-11
Each term has a common divisor of 
:
133 = 7*19, so the number in the blanks is .
