k=0.5 .. y=0.5 when x=0 .. anything to the power of 0 = 1 so 0.5=1*k.

on x=1 y=1.8

on x=1 equation will be y=ka
1.8=0.5a
a=3.6


I wish i had remembered that in addmaths !!

look for value of x to be zero. then a will become one and u will get K = 0.5.. then using k and any one value of x,y, find a..

Thanku so much both of u ! I got it

N btw shouldn be the value of y = 1.5

acha btao na .. ye kia hota hai .. !! also what is shear factor?

like agar (2,0) (0,2) (4,0) (0,4) houn co-ordinates aur shear factor 3 ho .. tu final co ordinates kia hongay ..

case 1 x axis invariant
case 2 y axis invariant.

yar mein ne tumhara ans likha he tha k lyt chali gae..
tumhe ans mil gaya.. ??

 

[MustafaMotani]

yup ratio of distance of new point from the invarient line and distance from the original point now i have got it!

exactly

laikin teen number same ane ki probability to 1/125 hui?

agar bola pucha hota k probability batao ke teeno number "5" ho to `1/125 hoti
agar bola hota k probability bato kay teeno number "9" ho to 1/125 hoti
lekin yaha puccha hai teeno number same hoto is liye multiply by 5 kia. yaha teen number 5 mein se kuch b hosaktay hai

 

[MustafaMotani]

MustafaMotani ???

ye shear isliye nhe q k yaha triangle ka area change ho raha hai, shear mein area change nhe hota

 

[MustafaMotani]

could you plz explain the upper bond and lower bond ??

suppose figure is 100 cm
it is said that this number is to nearest cm .... then we will divide 1 by 2, we will get 0.5 cm

to get upper bound add this number to original one and to get lower bound subtract it
U.B = 100.5
L.B = 99.5

If it would have said that 100 cm is to nearest 10 cm then we will divide 10 by 2 getting 5cm
now Upper bound will be 105cm
Lower bound will be 95 cm

Suppose it would have been said that 5000 cm is given to nearest 50 cm .... now divide 50 by 2 getting 25 cm

Upper bound = 5025cm
Lower Bound = 4975 cm

Hope u get it ..

Q. The function f is defined by f(x)=4x^2+2x+3 where x>=p.
Determine the smallest value of p for which f has an inverse.
Help desperately needed.

ans 2.75 hai.. ??

 

[MustafaMotani]

Haris Bin Zahid ans 2.75 hai.. ??

 

[Haris Bin Zahid]

ans 2.75 hai.. ??

Nah....its -0.25.

 

[MustafaMotani]

Nah....its -0.25.

sure.. ??

 

[Haris Bin Zahid]

sure.. ??

According to Marking scheme, -0.25 is the answer.....how have u calculated 2.75?????/

 

[MustafaMotani]

According to Marking scheme, -0.25 is the answer.....how have u calculated 2.75?????/

mein ne inverse nikal to inverse mein under root aya tha underroot( x -2.75)
to mein socha k under root mein 0 se kam fig nhe hosakta to 2.75

wese I think I have guessed how -00.25 ..!!
they derivated and equated the equation to 0 to get stationary point for x

ye maths ka sawal tha ya addmaths ka .. ?
