## cheesymcdouble one year ago Explain the distance formula. then use it to calculate the distance between A(1,1) and B(7,-7). Sorry I suck at this stuff.

1. pooja195

Well do you know what the distance formula is ?

2. pooja195

Hint : DISTANCE

3. cheesymcdouble

oh ok

4. pooja195

ok lets do that part later this is the distance formula $\huge d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ you are given 2 coordinates A(1,1) and B(7,-7). (x1,y1)(x2,y2)

5. pooja195

When you plug in the given coordinates you get this... $\huge d=\sqrt{(7-1)^2+(-7-1)^2}$ Solve from here. :)

6. pooja195

If you're stuck i can help you out! Just let me know! :)

8. cheesymcdouble

sorry i am i really do suck at math...

9. anonymous

so it's 10

10. anonymous

My way is easier

11. pooja195

@yomamabf they want you to use the distance formula read the directions. Congrats on giving the answer.

12. anonymous

oh i alwys thought my way was the distance formula we didn't even learn the real formula

13. cheesymcdouble

thank you so much @yomamabf sorry her way IS easier @pooja195

14. pooja195

@cheesymcdouble Read the directions that were provided they want the distance formula not her way.

15. pooja195

@yomamabf we need to do what the directions say.

16. cheesymcdouble

ok ok but it also wants the answer

17. pooja195

you get the answer after you calculate this : $\huge d=\sqrt{(7-1)^2+(-7-1)^2}$ Solve from here. :)

18. cheesymcdouble

alright thanks.

19. pooja195

Also theres another part to your question it asks explain the distance formula are you fimiliar with what the formula is used for?

20. cheesymcdouble

wait what

21. pooja195

This is why reading the directions is important.

23. pooja195

The distance formula is used to figure out the distance between 2 points. :)

24. cheesymcdouble

ok thanks

25. anonymous

fwiw both @pooja195 and @yomamabf applied the distance formula. The distance formula is just the specific application of the Pythagorean theorem when you have two points and want to know the distance between them. One method uses a formula, the other draws it out. Use the one that works best for you.

26. cheesymcdouble

ya the drawing one actually helps me best.

27. pooja195

@peachpi but they want the asker to use the distance formula .-.

28. pooja195

Oh nvm lol i thought they wanted the physical formula and not the drawing...

29. anonymous

yeah. it's the same either way. $$x_2-x_1=6$$ and $$y_2-y_1=8$$

30. cheesymcdouble

ok thanks guys

31. anonymous

lol

33. cheesymcdouble

34. pooja195

yep :)

35. cheesymcdouble

ok um how did you that...

36. cheesymcdouble

wouldnt it be 14

37. anonymous

you don't add 6 and 8. $\sqrt{6^2+8^2}$

38. cheesymcdouble

um ok then how do you...nvm i suck at this stuff and i dont want to frustrate anyone

39. anonymous

6² means 6x6 8² means 8x8

40. pooja195

lol we are here to help! You wont frustrate people :) 6^2+8^2 36+64=100 srt100=10

41. pooja195

*sqrt

42. cheesymcdouble

ohhhh ok thanks @pooja195 and @peachpi this now makes sense to me
