Answer:
It would be the first graph because |x| >5 is solved in two cases
The first case you keep everything the same, just get rid of the absolute value bars
x>5
The second case, you need to switch the sign and make the 5 negative
x<-5
When graphing you want to put an open circle on -5, and 5 because when it is < or > you have an open circle,
You then point the arrows going which ever way your sign is going, this is why the -5 is going to the left because the < sign is pointing left, and same with the 5, the arrow is going right because the > sign is pointing right
Hope this helps ;)
Answer:
Sₙ = √5/2 n (n + 1)
Step-by-step explanation:
<u>Given AP:</u>
<u>Rewriting as:</u>
- √5,√4*5,√9*5,√16*5,...
- √5, 2√5, 3√5, 4√5,..., n√5
<u>Common difference:</u>
<u>Sum of n terms:</u>
- Sₙ = 1/2n (a₁ + aₙ) =
- 1/2n (√5 + √5 + (n-1)√5) =
- 1/2n (n + 1)√5=
- √5/2 n (n + 1)
Sₙ = √5/2 n (n + 1)
