hope u understand

NOneed2speedd thank you so much for your help!! I did understand!! Can you also explain the last part c(ii) also.....like for those kind of questions how to answer.....I am always confused please help

 

[misscute406]

Take different points ON the region and see which gives the maximum numbers
like for eg. 7 (x) + 16 y = 23 animals

18 (x) + 11 = 29 animals

 

[NOneed2speedd]

18 (x) + 11 = 29 animals

Lol i said for example... right answr of Q.3 c ii is 29

yeahh i know i was just posting it because i'd already worked it out

Btw, should you draw tangent outside the curve or on inside the curve?

Guys can anyone of you please tell me how to find nth term of complicated sequences? Some steps please?
For example:
Sequence 1: 2,6,12,20,30
Sequence 2: 1,3,15,61,213

Please tell me some methods guys, I have an exam tomorrow and I don't want to lose marks in this question.

Of Course outside

 

[masterex567]

Of Course outside

And if you get the gradient as negative, when the curve is rising is the calculation wrong or are we supposed to switch it.

I Can't understand. .. can u shw example

sequence 1 is n^2 + n.

I think calculation is wrong as i never got negative gradient in rising curve

please try 5)e on may june 2013 43.
you only need to draw curve from points -3 to -0.2

Masterex567 please give me steps to find nth term, please. ((

M/J 2013 Paper 42 Question 4(d) explain please.

 

[Saad the Paki]

M/J 2013 Paper 42 Question 4(d) explain please.

To find the angle of the major arc we'll do 360-(39×2)
Then the formula for sector as u might know is => (X/360)*2*pi*r
Therefore => (360-(39×2))/360*2*pi*8.5
