Richiez: factorial1 sent me a mail saying his ba3 was very low...
he will be awarded a bonus 2pts at the end of this round only if other participants endorses it

so participants what do u av to say?

if dat should b d case,let 6 participant qualify den,he should b d sixth,bt if its stil 5,i dnt tink its rit cous sm also quitd cous of 1 or 2 reasns and mark wernt added 2 derz

smurfy: This answer is wrong. You gave 0.02m in your question but did not convert it to 2cm in the working. Please check. The correct answer is 5627 bullets.

0.02m>2cm,rem its stil diameta,radius=2/2=?

factorial1: #yimu... finally ba3 low! factorial this way >>^

ur point go speak 4 u,we only av 2questns 2 go,so no wories

Richiez: Participants be at alert! Quiz Master AlphaMaximux has chosen a number for :::Logodwhiz::: you'll be seeing the question shortly!

wat!! Wdf! Alpha maximum?? GOD

factorial1: wer's Dr.Gboy n' co..?

guest i gues

bitex2: You guys should keep it up!!!!
This time around the questions would be much more difficult and technical to that of yesterday..You all have got what it takes to reason critically..Kudos future ALBERT ENSTEINs

bt i tink say na d contestant go choos questns na

Jaryeh don turn 2 guest??

factorial1: @kendyzma, lowkey tinx abi...;? Iyen na make sence boss


Note: 3 questions r all what we'll be question'd on for 2day, to know those who are qualified for the FINAL, won't I run sha...? I no fit face my ogas'....

#Cheers

bos me just dey observ,congrats in advanc

Richiez: Next time all participants should endevour to send their usernames along with the correct answers to facilitate proper scoring

plz adjust it uniformly,we ought 2 b givin 2points na,4 d sec questn and nt 1 cous d 1st shouldnt b coutd

Jaryeh,u bad o,if i tel u 4 2go say u b my go,u go tink say na whinin,i tink u v nw sin it urself...i hail u.

Comin 2mao just 2 see my ogas hitin round 5,me don surenda patapata..kudos 2 all*

smurfy: Please adjust scoreboard o!

seconded,we rushd 2 anxa d 1st cous of d tim limit,mrova,my mb already finishd,and thot its ova 4 2day just saw d secnd questn nw

Y dnt bro richez gv me my 2points na,i got d anxa,morova we dat ansad questn1 b4 shouldnt b penalisd cous its nt our fault,xo if we ansad d second,it ought to reflect in our scors,shalom,morova...i doff cap 4 my ogas

See lets mov evrytin til 2mao,its already l8t.

Mbahchiboy: KENZIMA ARE U D GUY CALLED HONEY?..

hehe! NOP,

Idenyijoshua: Seems like i'm already packing my load to go. **feeling sad**

no go o,u 1 of d gurus i get 4 mind o,

Em.....7!

Hm.i already no d five lucky contestant...leme kip d names

aysuccess99: i knw dat u wld surely get it...gbosa 4 u o...u be d boss o*latest maths guru in d world o*

phd in whinin,

bitex2: Using integratin by substitution
let 2x be u
u=2x
du/dx=2
dx=du/2
$sinu.du/2
1/2$sinu.du
-1/2cosu=-1/2cos2x
ans -1/2cos2x + c

its nt sin2x...its sin^2x

statusnet: Solution
S sin²x

From our knowledge of trig
sin²x = ¹/₂ (1-cos2x)

so S ¹/₂ (1-cos2x)

= ¹/₂ S 1-cos2x

=1/2 (x-^sin2x/₂) + c

= x/2 -(sin2x)/4 + c

hm,bado

No b every1 do fmath 4 sec skul na..chai

aysuccess99: eheya...which simcard u dey use so dat i fit send mb 2 u o...if nah mtn tell me d procedure dat i can use 2 send mb 2 u o...i crious o.

haha,nt dat its at d red o...

aysuccess99: @factorial,kendzyma,jaryeh u guys don finish ni bluetooth me d ansa o.....

me just dey observ,mb no much again

bitex2: Multiples of an even no can never be odd.Hence if Q is even it implies that 3Q is even.
Ans 3Q

guy,tim iz nt yet up.

Alpha Maximus: Quiz Question By Quizmaster Alpha Maximus(this one is easier than the last)
Question: 2000 litres of fuel containing a 5% toluene mixture is available for a certain Chevy 265-cid V8 engine.This fuel is also designated for a superior engine, Omega41GB6, that requires a 25% mixture of toluene due to the need for better-quality octane-ratings. How many more litres of toluene must be added to the fuel to meet the superior engine's designations?

diz questn again?chai..wel i gues no1 can dodge it nw

factorial1: following though...no calculator, no pen(*coughs*) to solve, nothing nothing! Me Ah no du again jawe...

#teamleaveamfortheogas'

abeg b4 u go ..let's swap brain

jaryeh: Oga mi

y u on activat lowkey

Chai...only 1 question since

Master jaryeh!!!!!!!!

smurfy: He is right.

wat more can I say Yes sir!!!!

bitex2: Let sinx be = y
substitute for y
2y^2+3y+1=0
factorize
(2y-1)(y-1)=0
y=1/2 or 1
hence sinx=1/2 or 1
x=sin^-1(1/2)=30 or 150
OR
X=Sin^-1(1)=90
x=30,90,150 degrees
range of x is
30_<x_<150
pls i am a newcomer here i dont knw the particular email to message my solution to.PARDON

bro its 30 and 90....
