## MyDilemma one year ago Can someone help me with this? Find the distance between points m(6, 16) and z(-1, 14) to the nearest tenth

1. pooja195

$\huge~\rm~\sqrt{(x_2-x_1)^2+(y_2-y_1 )^2}$

2. pooja195

This is the distance formula can you plug in the numbers? :)

3. MyDilemma

(6^2 - -1^1)^2 + (16^2 - 14^1)^2 (36 - 1)^2 + (256 - 14)^2 35^2 + 242^2 1,225 + 58,564 = 59, 789 I think I did it wrong...

4. pooja195

Why did you sqrt everything? :O

5. MyDilemma

Well after I put the numbers in the formula I tried solving it... what am I doing wrong?

6. abb0t

What are the choices?

7. MyDilemma

There is no choices

8. pooja195

You dont need to sqrt everything

9. abb0t

Oh, in that case, it's 7.

10. MyDilemma

Okay but did i set the formula right?

11. MyDilemma

@abb0t how did you get that?

12. pooja195

sqrt((1-6)^2 + (14-16)^2)

13. abb0t

Not quite: $$\sf \color{red}{\sqrt{(-1-6)^2+(14-16)^2}}$$ which is approximately 7.28, but rounding to the nearest tenth is 7.

14. abb0t

$$\huge \sf \color{red}{7}$$ :)

15. pooja195

Thanks for the answer abb0t we didnt need it though

16. abb0t

If you have any more questions, @MyDilemma if you have anymore, ask me :)

17. MyDilemma

Thank you both for helping me, and helping me understand (::
