is that right or wrong ?

for the last question on paper 2 i got

128 for the greatest value when

and 32 for the smallest value

dunno if its right tho

i got that too... unfortunately it's wrong (because of the boundaries i think) but we should hopefully get 6/7 marks out of 8 for it!

That's the right answer.

Hmm, I don't think it is, because the value 128 comes from using x= -2, which is outwith the boundaries.

I completele sh*gged up the simultaneous equations in q.1. Feel ashamed to have been sitting higher maths just for that lol

i did that as well...but only cause i f**ked up part b

High 5 lol. That was the same reason I did it. At least now I can look forward to not having any exams left...I'm actually mentally exhausted from 4 exams in the last 3 days.

Would somebody be able to give me their answer for Question 3, Part b from Paper II please? I thought there was a mistake when I saw the question, but perhaps I'm wrong.

i couldnt get the answer to part 3 (b) either!

i subbed in the answer i got to part (a) into the equation given in part (b) then tried to do the discriminant and then make it equal to zero but got sumthin like 5 instead?!?

Q3B i got Q (4,-3) but probaly wrong

i subbed it in and it worked as i got a repeated root and then just got the y-value.

You have to set the two equations equal (the equation of the tangent from part ( a ) and the equation you are given in part B)

Then you solve and get only one value for x, which means it is also a tangent to this curve. You substitute the value of x into of the the equations to get the co-ordinates of Q.

No, i got an answer that fitted with the graph...it was (4,-y) ...cant remember what y was though

I got the radius of the other circle as root 13, so I said the radius of the larger circle was 5?
