Question

What is the distance between points (2, 8) and (7, 5)? Round to the nearest tenth of a unit.

Answer 1

how do i do this

Answer 2

\[d = \sqrt{(x _{2}-x _{1})^{2}+(y _{2}-y _{1})^{2}}\] distance formula your points are the ones given.

Answer 3

i got 4?

Answer 4

@iambatman

Answer 5

4 is wrong.

Answer 6

\(\sf (x_1,y_1),(x_2,y_2)\)
\(\sf (2,8)~~~,(7,5)\)

Plug them in to the formula that batman gave you :)

Answer 7

he gave me the wrong formula?

Answer 8

he said x2-x1 not x1-y1

Answer 9

oh nvm

Answer 10

The points you have been given is
\(\sf (2,8)\)
and that is in the form of \(\sf (x_1,y_1)\)

So
\(\sf x_1 =2 \\ y_1 =8\)

Answer 11

i got 22

Answer 12

then 4.7

Answer 13

is this right

Answer 14

What is your final answer?

Answer 15

If we plug in the numbers we get...

\(\sf\begin{aligned}\sqrt{\left( 7 - 2 \right)^2 + \left( 5 - 8 \right)^2} \end{aligned}\)

Answer 16

Solve from there.

Answer 17

\[\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\]
@iambatman gave you correct formula

Answer 18

i got 4.7

Answer 19

no wait

Answer 20

5.8?

Answer 21

@Michele_Laino @MCLover1477 i need help

Answer 22

we have to compute this:
\[d = \sqrt {{{\left( {2 - 7} \right)}^2} + {{\left( {8 - 5} \right)}^2}} = ...?\]

Answer 23

this is kinda easy um well so do you have multiple choice answers or do you have to put a number?

Answer 24

@alcathcart ?

Answer 25

we type an answer

Answer 26

oh ok

Answer 27

25+9

Answer 28

oh i think i forgot that negative times a negative is positive

Answer 29

ok! what is
sqrt(25+9)=...?

Answer 30

\[d = \sqrt {{{\left( {2 - 7} \right)}^2} + {{\left( {8 - 5} \right)}^2}} = \sqrt {25 + 9} = ...?\]

Answer 31

5.8

Answer 32

that's right!

Answer 33

wow thank you!! can you help with the rest just a few more
