Most difficult C2 paper I've done. Don't know why the lorry couldn't fit. Got a height of 4.992 or something.
oh my **** same struggle, i was so confused by that part... liKE WTF

Yeah that's what I ended up having too :/

Yes i got that as well. bound to get marks for it
4. Didn't get time to finish the log graph at the end >.<

8 marks to draw a line!

I subbed the x=3.6 into the equation and got y=4.992 too. Not sure if this was correct or even why it couldn't fit!

The height of the equation at x=1.2 was 3.392, along those lines anyway, the height of the lorry was 4.4. this means the lorry is higher than the roof of the tunnel meaning it wont fit through
7. the lorry was rectangluar but the curve wasn't, so you needed to find the height either side. which is why it told you it was symmetrical about X=3
8. [QUOTE=jaseho98;65553963]oh my **** same struggle, i was so confused by that part... liKE WTF[i/QUOTE]

Think you had to plug in X = 1.2 or 4.8 as they were the max height for van with width 3.6m. (Think about a tunnel as how you get closer to one side the roof gets lower) then the value for y was 4.352 or something which is less than 4.4
9. What intercept and gradient did you guys get for the log graph question? Obviously they'll all be a bit different, but roughly.

I got 0.65 for the intercept and 0.185 for the gradient
10. What did you guys get for the answers to the series questions?

I got exactly the same as that
12. The log graph was awful, felt impossible to draw a best line of fit, ended up with y intercept of 0.6 and gradient 0.2 which seems way off

got the same man
Doing an unofficial mark scheme, help if you want!

Thats what I got

The first I got 10+5+10 so 25 and the second one I got 0
17. Why did I do 10^0.7 for my y intercept
18. i think the range will be large because all the points differed so muchh

This is exactly what i got
20. i got 10^0.55 for my intercept and 0.2 for my gradient
