changed my mind

jhydebaba: pls show workings

area of triangle=1/2*side a*side b*sin(angle c)

Flytefalls: I love his wild thick hair!!! Long enough to twist with my fingers

Hi my friend!! I have been growing hair lately, I'd perm, hmmm.how would you like soft shiny black locks and curls so you can twist with your tiny fingers, ah, the thought alone makes me flush with anticipation.

***running his tongue over his lips***

johnpaul1101: Goodday all generals and gurus, please i need help with this circle geometry question:An equilateral triangle of side 20cm is inscribed in a circle. Calculate the distance of a side of the triangle from the centre of the circle?
After doing what i did, i got 8cm, but the answer here is 5.77cm, please how do i go about it?

I don't know how visible my drawings.

[a/sin(30)]=[20/sin(120)]
a=20*sin(30)/sin(120)

sin(30)=b/a
a=b/sin(30)

b/sin(30)=20*sin(30)/sin(120)
b=20*[sin(30)]^2/sin(120)
b=5.77cm

adaobi123: this one na dog chain ?

No dog go gree carry DAT chain, lol. Lefu my guy you favour Allah.

megatechgh: Please check the question very well, there are answer options from a - d....i was asked to choose the correct one.

lol, well I pick 80, that's c

Policewoman: No need hiding her ID. She is Nigerian.

Didn't you read the part where the police stated she received the money from a child living in her neighborhood?


Policewoman my 7.5 inches

@wkid what's your location?

doubleDx: Nice work Osita, how have you been man? It's been a while!

I am cool man, ehmmm, how madam?

megatechgh: Hello Gurus, I need a help here.

1. The shopkeeper has 6 barrel...5 - wine...1 - beer with the volume: 60 64 72 76 80 and 124 litres. The first customer buys 2 wine barrels. The second customer buys twice as much wine as the first customer. What is the volume of the beer barrel?
a. 60 litres b. 72 litres c. 80 litres d. 124 litres

c. 80
guy there is no shortcut for this one.

*we have five wine barrels and one beer.
*first man buys 2 wine
*second guy buys 2 times the volume of wine as the first man.
*for this to work the sum of any 3 volumes must equal to 2times any 2 other volumes.
*once you get the right combination the 6th unused volume should be beer.

Fetus: Kindly help with dis...(1) the sum of the first n terms of a G.P is 127 and the sum of their reciprocal is 127/64.the first term is 1. Find n and the common ratio respectively...(2)find 3 numbers in G.P whose sum is 13 and whose product is -64.....(3) resolve into partial fraction 7x+2/(2x-3)(x+1)^2.......tank u and God bless as u asist me....

question (3)
7x+2/(2x-3)(x+1)^2=A/(2x-3)+B/(x+1)+C/(x+2)

multiply all numerators by (2x-3)(x+1)^2 LCM style.

=[Ax^2+2Ax+A+2Bx^2-Bx-3B+2Cx-3C]/(2x-3)(x+1)^2

equating coefficients

[x^2]: A+B=0
[x]: 2A-B+2C=7
[]: A-3B-3C=2

manipulating:
A=2
B=-1
C=1

7x+2/(2x-3)(x+1)^2=2/(2x-3)-1/(x+1)+1/(x+1)^2

question (2)

3 numbers a, ar, ar^2

product: a*ar*ar^2=(a^3)(r^3)=-64
sum: a+ar+ar^2=13

so, ar=-4
making a subject: a=-4/r. manipulating the sum equation we get
4r^2+17r+4...
(4r+1)(r+4)
r=-4 or -1/4
a=1 or 16

possible answers
a=1, ar=-4, ar^2=16
a=16, ar=-4, ar^2=1

like. 1, -4, 16. or 16, -4, 1


question (1)

formula: Sn=a(1-r^n)/(1-r)
a=1

sum of nth terms (1-r^n)/(1-r)=127
sum of reciprocal of nth terms [1-(1/r)^n]/[1-(1/r)]=127/64

manipulating sum of reciprocals we get

(r^n-1)r/(r-1)r^n=127/64
but (r^n-1)/(r-1)=127
so, 127r/r^n=127/64
or, r^n=64r

fix that in the sum of terms
(1-64r)/(1-r)=127
so, 1-64r=127-127r
or, 63r=126
r=2

since, r^n=64r
then 2^n=64*2
2^n=128
2^n=2^7
n=7

n=7
common ratio = 2

alutacontinua: u no get pishure 're u a ghost

***frowns at her and points to the thread title***

alutacontinua: doesn't work dt way in Nigeria. Last time i checked, this forum is a nigerian forum, so, let's go by the rules!!!

my name is ALUTACONTINUA, not ? alutancontinuantata....

i gotta change my signature sef!!!

okey, Lizzy Aluntacontinuantata, Mogadishu like thier names long I suppose.

alutacontinua: that is not my name!!!

Lizzy, okwa ya?

alutacontinua: looks lyk she's slipping away afterall.... who knows odadamama mite av got to her!!!

hey, next time I'm going to spank your butt with my ****ko, Aluntacontinwanta!!!

alutacontinua:

What?

lao: Shows must of the ladies are not proud of their guy.

lets c urs

alutacontinua: what for

What is this thread for? Show us d bobo nah, eeeh Aluntacontinuantatatatatototaaaa, this your name dey make me stammer

Aluntacontinuanta, we dey wait o.

Fussbot: no

why?

190: Now flytefalls on the hot-seat and people asking for my picture
Why do people not value privacy she loves me the way I am and we are getting married soon
End of discussion

Forget matter

kpele , u still got alutscontinua.

double post

Flytefalls: I've nothing to share but this guy the clothed version

This must be 189.

ooseven: I see comprehension is also not your forte.

Just here to ruffle a few feathers as I always do before a Nairaland kamikaze, and you are just falling for it. Proves exactly my "smoothness" point.

Sadly I have arrived at my destination and won't be giving any fu.cks here till the man utd match. Maybe I check you up then.

Ok, see you then.

ooseven: Smooth guys don't bother about attention seeking posts like mine. It smacks of "complex" issues.

Don't mind me though, I will be banned within a week so don't keep tabs.

Was I seeking attention? I look like homo for your eye; why would I keep tab? Nice twisted rhetoric, though, lol.

team 190, all over the place
