Pls nairalanders, How do i get an authentic student visa 2 study abroad @ a low cost?

Hello nairalanders!
As an individual dt believes in justice&respect, i hereby seek 4 ur opinions&help on a problem,
A mobilepoliceman knocked on my sister's door & d next thing she heard was a dirty slap right on her face.
WHY? She inquired, d police startn ranting asking her why she destroyed his supposed land demarcator which probably was destroyed by a vehicle.
Why should a uniform man slap another man's wife?
Pls help coz i demand JUSTICE bt dont kno how 2 go about it[color=#990000][/color]

@ all i'm sorry4 d mistakes i made in d calculatns, here are d correctns,
Questn 1:
for joseph
loss=C.P-S.P.=500,000-S.P.
LOSS%=loss/c.p.*100
loss%=(500000-S.P.)/500000*100
x%=500000-S.P./5000
FOR OKORO
profit=S.P-C.P.=10000
PROFIT%=40%
but C.P. Of okoro=S.P. Of joseph
profit%=10000/C.P.*100=40
C.P. OF OKORO = S.P. of josep =25000
x=500000-25000/5000
x=475000/5000
x=95%
for d 2nd i'm sorry 4 d mistake d answewr is 25600 nt 25000
thanks 4 d understndn
@ wisdom , its nice avn someone lyk u in d house

I'll take a course on Calculus and Trigonometry next semester. Please I wanna sum1 to tell me the basic things I need to know in order to excel in the course.
@raylight, 2 b candid, as far as i'm concernd calculus is d most interestn and easiest aspect in maths
trig is also as interestn as calculus jjst stay focused bt abve all we nairalanders are always willn 2 learn
u may consult engineern maths

Q2: A wishes to keep some money in a saving deposit at 25% Compound Interest so that after 3yrs he can buy a car for N50,000. How much does he need to deposit now?
-----------------------------------
METHD1:
lt A=amount, R=rate, n=time
A=P(1+R/100)^n
A=50000, P=?, R=25%; n=3
, 50000=P(1+25/100)^3
50000=P(1+0.25)^3
50000=P(1.25)^3
50000=P(1.953125)
Divide tru
P=50000/1.953125
P=#25000.
D 2nd method is a bit long i wud av text i4 i had tym, it invlvs d use of d interest formla.

@guente02::
qustn 1: 4 josep, c.p=#500000
loss%=loss/c.p*100
i.e., x%=loss/#500000*100
loss=#500000x/100
loss=#5000x
4 okoro, C.P.=#500000-#5000x
prft%=proft/C.P.*100
40=#10000/(500000-5000x)*100
crss multiply
40(#500000-5000x)=1000000
20000000-200000x=1000000
200000x=20000000-1000000
200000x=10000000
x=10000000/200000
x=50%,
Wtch out 4 d others by GOD'S grace

@wi5dom
i dnt agree wit ur work 2 a greater extent coz
Its impossibl 2 diferentiate AREA 2 obtain volume u can only INTEGRATE , e.g
* to obtain d vol. Of a sphere, u integrate 4#r^2 to obtain 4/3#r^3. If u diferentiate u'll gt 8#r whch is wrong.
Pls shed mre lyt on dy/da, Coz there is notn lyk 'y' in d eqn.even if ure 2 diferentiate it ought 2 b dA/dr or dA/dH.
2 my understndn, d answer is right bt d workn is wrng , pls reply *digits*

@wi5dom, I'm sure its incomplete, prove me wrng by sending d soln @least we're all learning
bt i bet u as far as what u send is concerned it has prtically no soln
*digits*

@ funkystnl , thanks

@wi5dom, d questn is incomplete coz there ought 2 b a relatnshp btwn d RADIUS& height, tek a luk,
Vol. Of cyl= ¥r^2H
r=? , radius
H=? , height
¥=22/7, Pi
V=4cm^3, volume
subtitutn,
4=22/7*r^2*H
cross multiply
28/22=(r^2)H
(r^2)H=14/11, d only way 4ward is only when 1 of either 'r' or 'H' is given or there is a relatnshp btwn them,

@funkystanl, Pls can u giv me d name of a textbk(s) dt consist of d methods coz its nt clear, Or beter still send a solved problem wth it.
Hpe 2 hear 4rm u soon.
Thanks

@funkystanl , it seems i'm about 2 learn 4rm u coz i've neva heard of CROUT/TRIANGULAR decmpositn nor of gauss siedel and JACOBI pls shed more light pls,

@ mundus-Wshn u lots of understndn, stay focused
hope 2 mit u someday coz it seems we're educatnly compatible

All d methods are easy, 2 learn INDEPENDENTLY about CRAMMAR&matrix methods, get engineering maths( 5TH EDITN) by K.A. STROUD,
*4 GAUSSIAN method, consult ELEMENTARY LINEAR ALGEBRA by ANTON.

@choice2, i have just 2 years teaching experience as a maths/ furthermaths tutor at a private secondary school here in Badagry, lagos,
on the issue of computer literacy, i'm a literate but not an expert but can learn really fast by God's grace
pls, wats d nature of the job? i'm asking because i do not like to fail or perform below expectation whenever trust is placed on me.
THANKS SIR.

Here are few ways of solvn simultaneous eqns:
1 eliminatn
2 substitutn
3 graphical
4 crammers rule
5 guass/jordan eliminatn
6 matrix ( i.e cofactors)
OF THESE WAYS, HOW MANY ARE U CONFIDENT OF?[color=#770077][/color]

thanks. bt ive searched the website and ive found prctically nothing lyk dt

Is d pds direct 2 200 level also?

Pls throw mre lyt on PDS&UDS, their meanings, duratn & if its directly 2 100/200 level respectively. Thanks.

Hi guys!!! Dont tell me al d problms in maths are solved,
Lts keep ds thread alive

Tanx. Nyc learning 4rm u all

@babs adewa tanx wats ur qualificatn?
