Level 2 Further Maths Question

Original post by Retsek

a. Show that a = 10.5
b. Work out the value of b

I have a feeling that it's going to be a simultaneous equations question but I'm missing the 'magic step'

Have you done any questions like this before? They're quite common in Level 2 FM.

Due to similar triangles, the horizontal as well as the vertical lengths from P to Q and Q to R are in the ratio 2:3, as shown on the diagram above. Does that help? If you're still stuck please post all your working / thoughts.

Thanks a bunch Notnek.
PQ, x changes by 3, so if they're similar then QR x changes by 4.5. Adding them all together gets 10.5
PQ, y increases by 8b, so QR it increases by 12b. 21b in total gives 21b = 7, b = 1/3
A^ here I come hahah

Yeah man doing stuff like this in further maths gcse will make as, especially c1 a doddle XD.

Actually this type of question wouldn't appear in A Level and I expect that the majority of A Level students (who didn't do Level 2 FM) would struggle with it :smile:

Well stuff to do with line equations and when I did check on of the furhter maths gcse syllabuses, it basically seemed like c1.

Yes the coordinate geometry in Level 2 FM is often harder than C1.

This is true for me after looking at this.

I remember when I was doing this my textbook had this formula for dividing a line by a given ratio (e.g. M:N)

further maths gcse is not particularly hard

Yeah I did as in year 11 instead of further maths gcse. It was actually pretty hard as only 3 lessons a week like I would have had for gcse maths.

Think that sounds hard? I had to teach myself and go to teachers whenever I got stuck (which was constantly) only in the past 4 months have we had a specialist teacher come in to teach us. On the bright side it's taught me to be self-reliant for the future

I'm thankful that you made this thread, because I didn't realise there are some concepts in this that aren't even in C1 and C2. Considering sitting this qualification next year as a private candidate.

Well if you were able to self teach yourself then great although yeah I wouldn't sweat your grade too much if you only get an A or something as it's basically just an extra gcse that'll probably prepare you for a-level maths a bit better than just normal maths. Although yeah with maths it's good to do as much as possible to get overall better at it.

At the price of my social life (not that there was much of one to begin with) I'm on track for an A*, in our last mock I was 6 marks of an A^ but I'm very much happy with and A*
