For the circle question where "a second tangent was parallel to the first tangent" what did you guys get?

i think i got y=2x+10
what did everyone get for the completing the square one,then finding the maximum point? was it (3,22)?
For a couple of questions I wrote a couple of methods/answers - would the examiner mark all my working - or would I get 0 as I wrote more than one method?
Thanks :smile:
I got that duncat
For that question 4+12x+2x^2, I read that as 12x^2... will I get carried workings for the next question? I completed the square for it 100% correctly just misread the question...

Thats what i put... Wasnt sure about the minus in front of the whole thing but i put (3,22) and i think i put something like -(x-3)^2+22

I think i put -2(x-3)^2+22

I thought as it was parallel to the first tangent that it was y=3x+10 as for the first tangent I got a gradient of 3

I got 3,22 as well

when translating the curve by vector [3,0], was the new curve supposed to be drawn on the left or the right of the original?
The answer to the first one was 4x^2 - 9 ?
How are the maths grades calculated?
What was the answer for 2^k surds question with 5x 4^2/3 + 3x14^1/3?

yes actually i put -2 as well
what did everyone get for question 9 which was the inequality of k to have two real roots?

Were you meant to sketch the translation graph. I think it was just explaining it.

pretty sure it was just explaining
Whats the general consensus? Did everyone find it as hard as I did?
