syed1995 do you mean that cuz we ve used 1 no. already so remaining are 5 and we have to take any 2 from them?

Yes ..

right ok so see this question 12 either first part http://www.xtremepapers.com/papers/CIE/Cambridge International O Level/Mathematics - Additional (4037)/4037_w11_qp_13.pdf and tell me what the range would be

f(x) is a member of real number. coz of the graph of ln(X). it will be like this:

syed1995 do you mean that cuz we ve used 1 no. already so remaining are 5 and we have to take any 2 from them?

total numbers are seven after deciding the the first and last digits there will be 5 digits remaining to chose the other two

Thank you so so so so much. May you get A* in Add. Maths!

Inshallah!!

 

[Haris Bin Zahid]

ok! found out the reason!
y has a maximum value, right? so the coeffecient of (x-h)^2 must be negative, remember? so we will reject k = 2 as k is the coeffecient of (x-h)^2.

Thank you so so so so much! may Allah bless u with A* in all subs!

f(x) is a member of real number. coz of the graph of ln(X). it will be like this:
View attachment 11593

so the range would be any real number?

 

[ashiqbal]

so the range would be any real number?

yes. it would continue above and below the x axis, so there really is no limit to value of y.

d[ln(3x+4)^7] = 21/(3x+4) right ?
ashiqbal

 

[HarisLatif]

but for selecting the first number we'll right like this 3C1 as we can chose 1 digit from the three as first digit?

syed1995 plz answer bro

question is how many can sit in one taxi ?

 

[uzair2013]

question is how many can sit in one taxi ?

no...in how many ways can they sit with two particular persons must be in the same taxi???
By the way i did it it's 5C2 + 5C1

 

[ashiqbal]

d[ln(3x+4)^7] = 21/(3x+4) right ?
ashiqbal

yes

year?

 

[Haris Bin Zahid]

Is Additional Mathematics Classified book of Past Papers available? Cuz in Redspot topical, many questions are missing!

 

[ashiqbal]

no...in how many ways can they sit with two particular persons must be in the same taxi???
By the way i did it it's 5C2 + 5C1

he is asking that how many people can sit in one taxi? this must be given in the question!
by the way syed1995 i think that 4 or 3 people can sit in a taxi. Pakistan nahin hai!

and anyway, 5C2 + 5C1 IS 15!
