Question

Given S=n/2(n+1)
Complete the ordered pair.
D = {(n, S): (0, __)

Answer 1

given \[S=\frac{ n }{ 2 }(n+1)\]

Answer 2

you're given that n=0 so just plug in the value "0" into the given formula to get S

Answer 3

the ordered pair consists of (n,S) right?

Answer 4

I guess I am so confused with the lesson I am in I have read it over and over and it just doesn't make since to me

Answer 5

well the ordered pair consists of two numbers for x and y as in "(x,y)"... in this case you have an ordered pair of (n,S) and you're given the value of n=0 as well as the formulas for the S value, just plug in "n" to find "S" :)

Answer 6

plug in n=0 in the given? so like S=0/2(0+1) so it would 1 or did u mean something different

Answer 7

that's what I meant, so you should get 0 and your ordered pair will be (0,0)

Answer 8

okay thank you :)

Answer 9

np :)
