Look at points C and D on the graph:
A coordinate plane graph is shown. Point C is at negative 5 comma negative 1. Point D is at 0 comma 3. A segment connects the two points.
What is the distance (in units) between points C and D? Round your answer to the nearest hundredth.
5.50 units
6.40 units
9.00 units
41.00 units

Just use the distance formula \[\large \sf d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}\]

- anonymous

umm

- anonymous

Yes?

- anonymous

i not good with this

- anonymous

Ok...

- anonymous

i mean at all

- anonymous

0_0

- anonymous

Yeah. So...?

- anonymous

nvm ill just guest on it

- anonymous

my guest was 6.40

- anonymous

sorry i was helping someone. one sec

- anonymous

6.48 units

- anonymous

did you guess right?

- anonymous

idk i just followed the boxes

- anonymous

okay so do you know how to use the distance formula?

- anonymous

d=(x2âˆ’x1)2+(y2âˆ’y1)2âˆ’âˆ’âˆ’âˆ’âˆ’âˆ’âˆ’âˆ’âˆ’âˆ’âˆ’âˆ’âˆ’âˆ’âˆ’âˆ’âˆ’âˆš

lol i draw bad :3

- anonymous

it's fine haha, that's the formula. now you just need to plug in the coordinates.

- anonymous

mmmk

- anonymous

so the distance is in units right

- anonymous

wait theres no numbers in the question

- anonymous

yes, okay so
x2=0 x1=-5 y2=3 y1=-1

- anonymous

:O

- anonymous

there are, they're the points on the graph

- anonymous

|dw:1438109310692:dw|

- anonymous

|dw:1438109342451:dw|

- anonymous

so i just solve it from there

- anonymous

yes

- anonymous

|dw:1438109447004:dw|

- anonymous

right?

- anonymous

well, two negatives equal a positive so 0--5=5
and 3--1=4

- anonymous

|dw:1438109550865:dw|

- anonymous

yeah

- anonymous

|dw:1438109615688:dw|

- anonymous

mkk

- anonymous

|dw:1438109670630:dw|

- anonymous

plus or minus

- anonymous

yeah!
so 25+14=39

- anonymous

plus

- anonymous

so the answer is 41.00

- anonymous

cause it has to be to the nearest hundredth

- anonymous

no, what is the square root of 39?

- anonymous

|dw:1438109832801:dw|

- anonymous

19.5

- anonymous

nope

- anonymous

hmmm

- anonymous

do you have a calculator?

- anonymous

yes one sec

- anonymous

type in my last drawing

- anonymous

6.24

- anonymous

Yes!

- anonymous

|dw:1438109949897:dw|

- anonymous

^O^

- anonymous

but it has to round up so 6.40 units is your answer

- anonymous

thx

- anonymous

no prob

- anonymous

good job :)

- anonymous

ur great!

- anonymous

i only have one more question

- anonymous

okay but I have to go in a couple minutes so we have to hurry

- anonymous

The sets of numbers 7, 24, 25 and 9, 40, 41 are Pythagorean triples. Use what you know about the Pythagorean Theorem and explain or show why they are Pythagorean triples. Be sure to show your work for each set of triples!

- anonymous

I never learned this.. hm

- anonymous

me either

- anonymous

try googling your question. sometimes people have already asked it

- anonymous

ok thx

- anonymous

of course
