Mechanics?

yeap
i think so
it looks mechanics-ish

Mechanics?

does it really look like its mechanics ??
did u ever find a question in mechanics to find the nth terms >>>?

 

[ahmed abdulla]

are you sure this is the question ?
maybe you are missing something
cause you can't just get 14 and 16 in the answer when the height is only 2m !

ya i am sure .... when u sum it up .. you get this exprssiom

Yea.. it seems so .. but if it were GP. The sum to infinity is 8 and not 14 and nth term would be 2(1-(3/4)^n)/(1-3/4).
2-2(0.75)^n/0.25

8-8(0.75)^n would be the answer.

where is the question from?

looks like its not mechanics
no wonder i couldn't get it

i still cant get the head or tail of it

if i had my scanner working .... i would scan it .... i got a book ... and i am SURE it will come this year ... and saay i didnt tell u !!

LOL xD

its pure maths 1 ??

 

[Rutzaba]

hmm i thought og giving accel and i think s1 is enough of a threat i wouldnt risk with s2 . hmm the other grades would have covered up i guess

they dint -_-

well i cant understand but just tell me which paper it belongs to as it looks like pure stats and mechanics :/

 

[ahmed abdulla]

yes

they dint -_-

no worries u got into uni and ur equilance was outstanding mine in o level is 85 :/ i still have to go through that terribly anxious time :/

so no one knew how to solve the question !!!
as i said it was challenging

what question paper is this?!!

The answer equation you have given is incorrect or you are missing something out of the question..

if T1 = 2 , then T2 = 2*0.75 or not? Just answer me this. If it is Then what I have done is correct.

Verify this for me.
a = 2
r = 3/4
n = n ?

a)
Sn = a(1-r^n)/1-r
Sn = 2(1-0.75^n)/1-0.75
Sn = 2-2(0.75^n)/0.25
Sn = 8-8(0.75^n)

b)
Sinf = a/1-r
Sinf = 2/1-0.75
Sinf = 8
Can't be greater than 8.
