just look at the 7 row from the left mapapasin na sababa is full two box pero sa taas hindi that is enough para lumaki nang husto ang perimeter nang nasa baba. its more optical illusion for me.
just compute the area of the different colors dun palang iba na resulta. bulag lang ang hindi makakapansin na mag kaiba ang size nang dalawa, maybe a protractor will help. just look at the "angle" sa baba ay mas malaki ang angle.

ang problem diyan tol.. pero hindi ko sure eh.... iyong paglilipat ng mga parts... kasi kailan man hindi pwedeng magkaganyan tol kasi the same parts ang ginamit kaya dapat the same din ang total nila niyan... kung papansinin mo iyong above figure, ang area niya e mas malaki pero sa ibaba, nagkulang na ang area... maaaring ang nandaya diyan eh iyong outline na black.. kasi mapapansin na may mas makapal na noong nailipat eh....

parang equation iyan tol eh..... 1+2+3=2+1+3 ganoon tol... application ng commutative property of equality tol... tapos ang sum is ALWAYS equal to its addends... sa Gestalt Psychology lang na "the total is more than the sum of its parts".... that is my point of view....

mga kasymbianize pahelp naman sa calculus pagpasok ko kasi 2nd year na ako ECE course ko gusto ko magadvance study para di na ako nahihirapan

As for me, I was very curious at this one and tried to solve it before I googled the answer and I was right about my speculations. May pagka-optical illusion na akala mo straight line ang hypotenuse ng 2 triangles. So the ? square is somewhere at the left side the triangles' hypotenuse.
First triangle, (i just googled a calculator for right triangle and input the base and ht.) is 20.6 degrees while the other is 21.8 degrees... so di sila straight bumubuo ng straight line. cause they have different slopes.

Anyway, napatunayan kong bobo nga ako sa math ngaun at sa office kasi walang scientific calc so I need to google everything. nyehehe.. at least I learned a lot.

heheheh! try ko rin sana i Google pero tinatamad ako eh... heheheh! tama hinala ko na dahil sa outline nito na black.. iyon ang nag ayos ng hypotenuse para magmukhang magkpareho sila ng slope....hehehe! I hate calculators.... pinapadali nito mga problems sa math... mas maganda mano mano ^^ I miss competitions

if you take up engineering magiging bestfriend mo ang calcu.

kaya pala noong nacopy ko sa photoshop hindi talaga tumatama..

ayun!!

mga henyo..

paano kunin ang intersection encircled with a red mark? thanks guys!

i told you tama hypothesis ko mag kaiba nang angle yung dalawa isang tingin lang naman obvious obvious naman bobo lang hindi makakapansin

Hi, hindi ba dapat "-100 " yung nasa quadrant 3 at 4? I'll try this one..

pwd kang mag analytic at trigo pero mas madali kpg trigo, yung intersection ay (x,y): (-131.5,226).,sadya ba yung maling plotting?

ok lang yun basta hindi nadesignate yun intersection ng mga axis as origin O0,0), para mkta lang natin na along x-axis sya.,para hindi lang straight line ang makikita..ehe.,

 

[angel naomi]

Tina-try ko sagutan ito pero parang hindi legit yung answer na nakukuha ko. (-32.5, 132.5) ung coordinates na nakuha ko na pag pinlot mo, napakalayo sa nasa graph ni median..

ilalagay ko na ba ang equation ko? o maghahanap tayo ng ibang makakasagot ng tanong nya? I just used the point slope equations ..

 

[miggy93]

mga sir, pade pahelp? dko kasi masagutan yung assignment namen tsaka hindi ko masyadong nagets yung lesson namen kanina e. yun. ito yung problem, sana may makatulong.

Find the centroid of the solid generated by revolving about the indicated axis the area bounded by the given curves.

1. 2x + y = 2, x = 0, y = 0 about x = 0

thanks in advance sa makakasagot, pati na rin sa magtatry.

haha, mali pala yung x axis. namamadali po kasi ako. thanks. talagang -131 something ang sagot

 

[NRX10]

ang galing naman ng thread na ito very useful kaysa sa google kasi dito may totoong tutor​

 

[median27]

prior po sa tanong ko, kinocompute ko po kasi ang cut and fill sa excel, nagulat lang ako na -131 something yung intersection ng existing ground at roadbed considering the required sideslope of the cut (masyadong malaki).

kaya yung sa plot, mali po na nka intersect sa highest line, mageextend pa yung highest line upward with the same slope.

anyways thanks sa nakasagot.

A=1
xc=1/3
yc=2/3
ata...

,mali yung pagkaplot kya kung titignan mo ang sagot hnd tlaga possible.,
yung eq. ng upperline ay 18y+17x=1832.5, middle line y+x=94.5 and panlito lang ang huli,2 equations n 2 unknowns,you can get an answer

TAMA,kaya pala,ehe khit hindi maintindihan,ehe,dinrawing gamit ang excel?.

,ang sagot ay
Csubx=0
Csuby=1/2
Csubz=0
bali ang centroid ay
C: (0,1/2,0)
,sana nakatulong.,ehe
