i didn't do tank question!! i got the total distance right!

 

[NOneed2speedd]

I got 1430m as total distance. average speed as 11.9
and 684m for the cylindrical tank question

I also got exactly same answers

and hw to do the second part of the m, n questionin which they asked the positive value of x using answer (a)
i didn't understood so applied quadratic formula in the end

oh you replace m and n
it was (x+2)^2 - 10 = 0
so x+2 is root of 10.
so x is root of 10 - 2
which was 1.16

i didn't do tank question!! i got the total distance right!

why man... It was easy just u had to use vol.discharge=crossara×speed×time

 

[masterex567]

I also got exactly same answers

oh great! for m and n, did you complete the square or use simultaneous equations?

 

[NOneed2speedd]

oh you replace m and n
it was (x+2)^2 - 10 = 0
so x+2 is root of 10.
so x is root of 10 - 2

oh

I used completing square technique

 

[misscute406]

i didn't know that!! i literally cried after the exam!! math is my fav subject!! I am very heart broken!!

why man... It was easy just u had to use vol.discharge=crossara×speed×time

 

[misscute406]

hey the locus!!! how was it?? someone draw and send na!! please!!

 

[NOneed2speedd]

Don't worry man p4 is remaining

 

[misscute406]

In Sha Allah hope to do well then!!

Don't worry man p4 is remaining

 

[masterex567]

hey the locus!!! how was it?? someone draw and send na!! please!!

perpendicular bisector of AC, and then a circle of 2 cm radius ( 4 cm diameter)
shaded the part between bisector and circle

 

[NOneed2speedd]

hey the locus!!! how was it?? someone draw and send na!! please!!

As far as i can remember!

 

[misscute406]

As far as i can remember!

yaaaaaaaaaaaaaaaayyyyyy!!!! i got it i got it!! Alhamdulillah!!

 

[misscute406]

then what other questions were there?? functions was easy!!

As far as i can remember!

 

[masterex567]

I used completing square technique

can you explain how to use square technique for that number please?
also, do you know if they accept different method than specified in ms?

 

[masterex567]

then what other questions were there?? functions was easy!!

functions was easiest!
did you get 11 as x for the square thingy
and 8 for length fg of the triangle

 

[misscute406]

which one?? funtions??

can you explain how to use square technique for that number please?
also, do you know if they accept different method than specified in ms?

 

[masterex567]

which one?? funtions??

no for the m and n thing. i used simultaneous equations and got the answer...
