1. Does anyone know the working for the the last question?
2. (Original post by etothepiiplusone)
Come on Steven, these are basic exponent laws!
Please can you explain how it's wrong? Sorry i don't get it😂

If m = 2
2^m = 4
So (2^m)^3 = 64
64 / 8 = 8
8 = 2^3
Sorry I can't see what I did wrong!

Ok

To use an alternative exponent law. You should know
lol, i made the same exact mistake, how much marks would you lose?
As unfortunate as it is, it's good to know others made the same mistake. The boundaries will probably be lower as it was a hard paper.

It was out of 4 marks I think:

So 1 mark by substituting in x and y into Pythagoras
1 mark for simplifying Pythagoras theorem
1 mark for finding x in terms of y by square rooting both sides
1 mark for finding the area

We probably got at least 2 or 3 marks. Did you get 16/5? That's what I got.

Oops... thank you!

It's really pot luck or lots of bashing to factor out the three.

Now we complete the square on the inside as

So

Done!

Surely
(2^m)^3
= 8^3m not 2^3m?
Correct me if I'm wrong!
I nearly did this mate hahahaha.

Where i went wrong was thinking of it as (2x^m)^3
This would have then been 8x^3m
This might have been what you thought like me.
Fortuantely i was able to spot it XD

Hope it helps

im pretty sure q8 was 106.1 (since angle = 106.06...)
yes exactly
10. (Original post by Boil)
yes exactly
I originally put 106.7. I then edited.

ok thanks, could u remind me what question 9: x=-2 was again? and question 10 please

I'd love to but I can't remember myself. Anyone?

I think it will be around 137-141. Most of the time with the past papers, I knew what to do immediately. In today's paper though, I really had to think about what to do, especially for the last question and the trig one where you had to find k. I thought Thursday's paper was alright though. I guess that was AQA's way of tricking people into thinking today's paper was going to be good.
That's exactly what I found too. This paper required so much more thinking about actually what you had to do to get the answer, and I didn't really get that on Thursday or on any other past paper. I do hope the A^ grade boundary is low though, I messed up some easy questions and made silly mistakes throughout!

Yeah, I messed up some easy questions too. For the find the area of the rectangle question I found the area of the triangle instead. I made a stupid mistake on the circle theorem question. I made a substitution error on the quadratic simultaneous equation. I got stuck on the 'find the value of cos in terms of k' and guessed incorrectly. Hopefully I still get method marks lol. Really hope I scrape enough marks for A^.

Wait what was the find the area of the rectangle question
16. (Original post by gcse0)
I got 19.2 units squared for the area of the triangle - is that right?
I also got 19.2
17. (Original post by gunnafail123)
but it was asking for the difference from 20th term to 8th term not 8th to 20th
But I am pretty sure it said between rather than from...to

it was the weird question where you were given two inequalities and you had to show that there was only one solution for both of them
the inequalities were -11<5x<=5 and the other simplified inequality was 2x+3<0

Dammit, I misread the question since I thought they asked for 1 solution that cannot be in both inequalities.
-11/5 < x <= 1
x < -3/2

How many method marks will I get since I got to the end and wrote the wrong answer?

Thanks. @Boil if you plot the inequalities on a number line (yeah I know) it's clear to see -2 is the only answer: https://www.desmos.com/calculator/um4a23ffwt

Otherwise it is clear that , the first two sets being the integer solutions to the two inequalities
