You would use the function root(Xsub2-Xsub1)^2+(Ysub2-Ysub1)^2.
Now plug in your numbers.
This gives you root(7-1)^2+(5-(-3))^2.
Simplify to root(6)^2+(8)^2. Simplify again to root36+64.
Simplify one more time to root 100. now solve.
Your answer is 10.
Answer:
flip it around 9/13 reciprocal would be 13/9
A is located, as you look A is past -2 almost hitting -3 making the mark 2.8 so the answer is A
The sequence is geometric, so
for some constant r. From this rule, it follows that
and we can determine the first term to be
Now, by substitution we have
and so on down to (D)
(notice how the exponent on r and the subscript on a add up to n)
2/4= 10/20
1 4/10=14/10 14/10=28/20
10/20×28/20=7/10
I hope this helped!!!:)
