# Few C1 questions watch

1. http://www.mei.org.uk/files/papers/2011_Jan_c1.pdf

Can someone help with 11 part (ii) and (iii) and 12 part (iii)

On part 2 I got to the step of 0.5 x root 160 x root 40.

Does it expect us to do this, or is there a simpler way of approaching? I just did the long way lol of working out the square root of 1600 which is 40..

And I have no idea what to do for (iii) Once I can get the first step of proving it I can do the rest.

Oh and when the questions say show that the equation of blah blah blah has only one real root. Is that just asking b^2 - 4ac = 0 ?

and...

question 6.

2. For 11 part two, it's best to draw a diagram and then join the points up

Find the heigh and times this by the length and divide by 2

Sorry, haven't got time to do the rest
I've got an exam in an hour 😂
