use the graph write ratio in simplest form

OpenStudy (highschoolmom2010):

OpenStudy (highschoolmom2010):

OpenStudy (jdoe0001):

AB and BD for the first ratio, are pretty much given, just look at the x-coordinate values from A to B, and then from B to D EC is also just by looking at the y-coordinate, from E to C, how many units now, AE can be obtained by using pythagorean theorem AE = \(\sqrt{AC^2 + EC^2}\) now as far as the slopes of EB and ED just look at the points (x, y ) coordinates http://www.mathwarehouse.com/algebra/linear_equation/images/slope-of-a-line2.gif

OpenStudy (highschoolmom2010):

so for 33 it is .....5/6

OpenStudy (anonymous):

for 33, AC is 6 BD is 6 so the ratio of AC:BD is 6:6 that simplified is 1:1

OpenStudy (highschoolmom2010):

can you explain it im sooo confused on how to do this

OpenStudy (anonymous):

well AC is the length from point A to point C, which is 6 BD is the length from point B to point D, which is 6 #33 is asking for the ratio of AC/BD, which is 6/6 6/6 simplified is 1/1

OpenStudy (highschoolmom2010):

oh i misread -_- ok

OpenStudy (anonymous):

33 is simple because you can just count the distance from A to C and from B to D 34, you have to use the distance formula to find the distance from A to E

OpenStudy (highschoolmom2010):

ok so refresh on how to do that

OpenStudy (mertsj):

\[d=\sqrt{(x _{2}-x _{1})^2+(y _{2}-y _{1})^2}\]

OpenStudy (anonymous):

\[AE = \sqrt{AC^{2} + EC^{2}}\]

OpenStudy (anonymous):

but yes, what @Mertsj said haha

OpenStudy (highschoolmom2010):

oh ok so how do i do that

OpenStudy (anonymous):

well you know that AC is 6 find out what EC is by looking at the graph looks like EC = 8 so \[AE = \sqrt{6^{2}+8^{2}}\]

OpenStudy (anonymous):

\[AE = \sqrt{36+64} = \sqrt{100} = 10\]

OpenStudy (highschoolmom2010):

ohhh that makes sense

OpenStudy (anonymous):

yep, not just do the same thing we did for 33

OpenStudy (highschoolmom2010):

can you rephrase that for me

OpenStudy (highschoolmom2010):

im confused as to what you mean

OpenStudy (highschoolmom2010):

@nincompoop help me maybe...?

OpenStudy (nincompoop):

so what part are you confused?

OpenStudy (highschoolmom2010):

what i am supposed to do after i have figured out what AE is

OpenStudy (nincompoop):

look for segment EC

OpenStudy (highschoolmom2010):

ok i found it

OpenStudy (highschoolmom2010):

it is 8..?
