do you know the formula for the area of a square?
anonymous
  • anonymous
no,i dont remember
AriPotta
  • 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
  • anonymous
Ohhh.
anonymous
  • 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

is that no one on page b?
AriPotta

thanks:)

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

yup,7.2
anonymous

about
AriPotta
  • AriPotta
ehh, i'd put 7.3 unless your teacher asked you not to round?
anonymous
  • anonymous
well, i am allowed to use a calc, and it said 7.2......
AriPotta
  • AriPotta
7.2801..., that's why i said 7.3, but put 7.2 if you want :)
anonymous
  • anonymous
ill put 7.3:)
anonymous

ok, another one i need urgent help on
anonymous

number two on page b
AriPotta

so 13^2 + 12^2 = ?
anonymous
  • anonymous
well, 11.48 144
anonymous
  • anonymous
155.48?
AriPotta
  • AriPotta
remember Pythagorean theorem... a^2 + b^2 = c^2 so 13^2 + 12^2 = c^2 169 + 144 = c^2
anonymous
  • anonymous
oh
AriPotta
  • AriPotta
313 = c^2, so what does c equal?
anonymous
  • anonymous
are a and b aleeady squared?
anonymous
  • anonymous
o square 313
AriPotta
  • AriPotta
right, so what's the square of 313?
anonymous
  • anonymous
9769
anonymous
  • anonymous
from google cqlculator
AriPotta
  • AriPotta
i meant square root, sorry
anonymous
  • anonymous
o
anonymous
  • anonymous
i entered '313^2' into the search engine
AriPotta
  • AriPotta
yea, i know what you did, but this is what you need to do: \[\sqrt{313}\]
anonymous
  • anonymous
ohhh duh. *hits own face*
anonymous
  • anonymous
17.69
AriPotta
  • AriPotta
yup
anonymous
  • anonymous
yay:) *writes*

Ari, the one you just hlped me on, was that the one withbthencoordinate points listed or the one about george?
AriPotta
  • AriPotta
so the hypotenuse is 17...do you see how i got the the lenght of the one leg?
anonymous
  • anonymous
and tnx
AriPotta
  • AriPotta
with the coordinates listed
anonymous
  • anonymous
tnx,let me look at ur most recent snapshot
anonymous
  • anonymous
ok.mcan you explain what x is?
AriPotta
  • 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
  • anonymous
oh.no. how?
AriPotta
  • AriPotta
did you notice how the area of that square was 225? how can we find the side length of a square?
anonymous
  • anonymous
sq root oof area
AriPotta
  • AriPotta
yep, and that's how we got 15, does that make sense?
anonymous
  • anonymous
15
anonymous
  • anonymous
yes,ma'am
AriPotta
  • 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
  • anonymous
15+x=17?
AriPotta
  • AriPotta
what's the Pythagorean theorem?
anonymous
  • anonymous
a^2+b^2=c^2
anonymous
  • anonymous
15^2+b^2=17^2?
AriPotta
  • AriPotta
yep
anonymous
  • anonymous
yay so i solve?
AriPotta
  • AriPotta
if you know how to. show me what you think you do
anonymous
  • anonymous
3.8-4.1
AriPotta
  • AriPotta
you're doing the square root again!
anonymous
  • anonymous
ii mean the other way around
AriPotta
  • AriPotta
don't! lol
anonymous
  • anonymous
srry :s im addicted to sqnroots i think
anonymous
  • anonymous
lol
anonymous
  • anonymous
er,sobhow then?
AriPotta
  • AriPotta
what's 15^2?
anonymous
  • anonymous
oooh 225
AriPotta
  • AriPotta
and what's 17^2?
anonymous
  • anonymous
289
AriPotta
  • AriPotta
right, so 225 + b^2 = 289. what do we do now?
anonymous
  • anonymous
subtract
anonymous
  • anonymous
289-225
anonymous
  • anonymous
=64
AriPotta
  • AriPotta
so b^2 = 64...what does b equal?
anonymous
  • anonymous
8
AriPotta
  • AriPotta
yep
anonymous
  • anonymous
:0 lol all that for 8
AriPotta
  • AriPotta
yea lol
anonymous
  • anonymous
tnx:)
anonymous
  • anonymous

anonymous
  • anonymous
the one after this one
AriPotta
  • AriPotta
3 on page a?
anonymous
  • anonymous
yes
AriPotta
  • AriPotta
i think all you have to do for that is \[\sqrt{89}\]
anonymous
  • anonymous
it has answer choices
AriPotta
  • AriPotta
i know, what's the square root of 89?
anonymous
  • anonymous
9.43
AriPotta
  • AriPotta
9.43 matches which answer choice...?
anonymous
  • anonymous
d:0
AriPotta
  • AriPotta

AriPotta
  • AriPotta
"as the crow flies" i have no idea what that means lol
AriPotta
  • AriPotta
oh wait! that's the hypotenuse!
anonymous
  • anonymous
same:0
AriPotta
  • AriPotta
the hypotenuse is your answer
anonymous
  • anonymous
oh
anonymous
  • anonymous
explain plz?
AriPotta
  • 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
  • anonymous
ok.tnx the kms i just draw on the plane?
anonymous
  • anonymous
him going south then east?
AriPotta
  • AriPotta
south is down, east is right
anonymous
  • anonymous
ok,so i draw that and thats it?
AriPotta
  • AriPotta
the hypotenuse, c, is the answer
