Step-by-step explanation:
Answer:
S
ThenSn=n(a1+an)2Sn=n(a1 + an)2 , where nn is the number of terms, a1a1 is the first term and anan is the last term. The sum of the first nn terms of an arithmetic sequence is called an arithmetic series .

Answer:
200 in the x-direction by -346 in the y-direction
Step-by-step explanation:
This vector lies in Quadrant IV.
The horiz. component is 400 cos (-60°) = 400(0.5) = 200, and
the vertical comp. is 400 sin (-60°) = 400(-0.866) = -346
The combination form is 200 in the x-direction by -346 in the y-direction, or (as a vector) <200, -346>
You can say 8/10 = 80/100 ⇒ 80/100 is bigger than 79/100 :)))
Answer:
3
Step-by-step explanation:
6 cups require 2 cups
9 cups require-------x
Cross multiplication
9x2 = 6x
18 = 6x
x= 3
Another way to think about:
6 + half of 6 = 9
Then
2+ and half of 2 = 3
6 is 3 times more than 2
9 is 3 times bigger than 3
