which ones do you need help on?

- anonymous

um, all of them except number one on page b

- AriPotta

do you know the formula for the area of a square?

- anonymous

no,i dont remember

- AriPotta

l x w = a, remember? but for a square, since the length and width are equal, you can just say s^2 = a

- anonymous

Ohhh.

- anonymous

yes. i was wondering however about the problems at the top of page b

- AriPotta

oooh i misread what you said. sorry, i'm tired

- anonymous

its alright

- anonymous

- AriPotta

do you know what the answer is? or what you think the answer is?

- anonymous

yup,7.2

- anonymous

about

- AriPotta

ehh, i'd put 7.3 unless your teacher asked you not to round?

- anonymous

well, i am allowed to use a calc, and it said 7.2......

- AriPotta

7.2801..., that's why i said 7.3, but put 7.2 if you want :)

- anonymous

ill put 7.3:)

- anonymous

ok, another one i need urgent help on

- AriPotta

doing*

- anonymous

whic one is that?

- AriPotta

that's number 4 on page a

- AriPotta

so 13^2 + 12^2 = ?

- anonymous

well, 11.48
144

- anonymous

155.48?

- AriPotta

remember Pythagorean theorem... a^2 + b^2 = c^2
so 13^2 + 12^2 = c^2
169 + 144 = c^2

- anonymous

oh

- AriPotta

313 = c^2, so what does c equal?

- anonymous

are a and b aleeady squared?

- anonymous

o square 313

- AriPotta

right, so what's the square of 313?

- anonymous

9769

- anonymous

from google cqlculator

- AriPotta

i meant square root, sorry

- anonymous

o

- anonymous

i entered '313^2' into the search engine

- AriPotta

yea, i know what you did, but this is what you need to do:
\[\sqrt{313}\]

- anonymous

ohhh duh. *hits own face*

- anonymous

17.69

- AriPotta

yup

- anonymous

yay:) *writes*

- anonymous

thatd be which 1?

- AriPotta

that was 4 on page a

- anonymous

tnx,and http://assets.openstudy.com/updates/attachments/5088ba01e4b0524190915d7e-aripotta-1351139613752-capture4.png ?

- anonymous

Ari, srry, im having trouble with number 2

- anonymous

o

- AriPotta

ok

- anonymous

tnx:)

Ari, the one you just hlped me on, was that the one withbthencoordinate points listed or the one about george?

- AriPotta

so the hypotenuse is 17...do you see how i got the the lenght of the one leg?

- anonymous

and tnx

- AriPotta

with the coordinates listed

- anonymous

tnx,let me look at ur most recent snapshot

- anonymous

ok.mcan you explain what x is?

- AriPotta

yea, i was just asking you if you knew how i got 15 for the length of the one side? because if you know this, you can basically do any question similar to this

- anonymous

oh.no. how?

- AriPotta

did you notice how the area of that square was 225? how can we find the side length of a square?

- anonymous

sq root oof area

- AriPotta

yep, and that's how we got 15, does that make sense?

- anonymous

15

- anonymous

yes,ma'am

- AriPotta

so if we know the hypotenuse is 17, and a leg is 15...how can we go about finding the other leg length?

- anonymous

15+x=17?

- AriPotta

what's the Pythagorean theorem?

- anonymous

a^2+b^2=c^2

- anonymous

15^2+b^2=17^2?

- AriPotta

yep

- anonymous

yay
so i solve?

- AriPotta

if you know how to. show me what you think you do

- anonymous

3.8-4.1

- AriPotta

you're doing the square root again!

- anonymous

ii mean the other way around

- AriPotta

don't! lol

- anonymous

srry :s
im addicted to sqnroots i think

- anonymous

lol

- anonymous

er,sobhow then?

- AriPotta

what's 15^2?

- anonymous

oooh 225

- AriPotta

and what's 17^2?

- anonymous

289

- AriPotta

right, so 225 + b^2 = 289. what do we do now?

- anonymous

subtract

- anonymous

289-225

- anonymous

=64

- AriPotta

so b^2 = 64...what does b equal?

- anonymous

8

- AriPotta

yep

- anonymous

:0 lol all that for 8

- AriPotta

yea lol

- anonymous

tnx:)

- anonymous

ok, so one more

- anonymous

the one after this one

- AriPotta

3 on page a?

- anonymous

yes

- AriPotta

i think all you have to do for that is \[\sqrt{89}\]

- anonymous

it has answer choices

- AriPotta

i know, what's the square root of 89?

- anonymous

9.43

- AriPotta

9.43 matches which answer choice...?

- anonymous

d:0

- AriPotta

yup

- anonymous

one more and tnx so much!

- AriPotta

- AriPotta

whichever one we didn't do already and that you feel comfortable doing

- anonymous

umm..let me c

- anonymous

6 pg b

- anonymous

doing it...

- AriPotta

"as the crow flies" i have no idea what that means lol

- AriPotta

oh wait! that's the hypotenuse!

- anonymous

same:0

- AriPotta

the hypotenuse is your answer

- anonymous

oh

- anonymous

explain plz?

- AriPotta

well crows can fly over water and stuff. we'd have to walk around it. so "as the crow flies" is through the water or whatever, so it's the hypotenuse

- anonymous

ok.tnx the kms i just draw on the plane?

- anonymous

him going south then east?

- AriPotta

south is down, east is right

- anonymous

ok,so i draw that and thats it?

- AriPotta

the hypotenuse, c, is the answer
