1. satellite73 Group Title

which one?

2. helpmeplz311 Group Title

both. its 11 problems

3. helpmeplz311 Group Title

help with whatever

4. helpmeplz311 Group Title

any help is appreciated

5. satellite73 Group Title

they all use the distance formula, which is pythagoras

6. helpmeplz311 Group Title

ok.

7. helpmeplz311 Group Title

can u do the first as demonstration ill try the others?

8. satellite73 Group Title

page B number 1 i will do if i can read it properly

9. helpmeplz311 Group Title

tnx

10. satellite73 Group Title

you have two points labelled A and B and no numbers to go with them so lets count

11. helpmeplz311 Group Title

mm,ok

12. helpmeplz311 Group Title

ok

13. satellite73 Group Title

to get from A to B you go 7 units right, and 2 units down at least that is what i see

14. helpmeplz311 Group Title

uh huh

15. helpmeplz311 Group Title

let me verify

16. satellite73 Group Title

|dw:1351133689882:dw|

17. helpmeplz311 Group Title

brb,counting

18. helpmeplz311 Group Title

how did you get seven again?

19. satellite73 Group Title

we want $$d$$ which is the hypotenuse of the right triangle with one side 7 and one side 2 by pythagoras, we get $d^2=7^2+2^2$ $d=\sqrt{7^2+2^2}=\sqrt{49+4}=\sqrt{53}$

20. satellite73 Group Title

i counted how many steps i had to go the the right

21. helpmeplz311 Group Title

did you count a or b?

22. satellite73 Group Title

i just counted them, i did not compute anything at all just went "one, two, three, four, five, six, seven"

23. helpmeplz311 Group Title

ok.

24. helpmeplz311 Group Title

so we aare solving for the hypotnuese

25. helpmeplz311 Group Title

ok, so sq rt 53 is about 7.2

26. satellite73 Group Title

yes in each case that is the basis for the distance formula

27. satellite73 Group Title

like for number 3 on the same page, from A to B is 4 steps right, 4 steps up distance is $d-\sqrt{4^2+4^2}=\sqrt{16+16}=\sqrt{32}$
