Why question6 is A in matrices

[Daniel55555555]

I mean E

[Dan1995]

I mean E

The information tells you that the elements in the matrix are the sum of the row and column number for that matrix. For example, the first element is in column 1, row 1, therefore it is a 2. (1+1=2)
The element in row 1, column 2 is a 3. (1+2=3)
Row 2, column 1 is a 3. (2+1=3)
Row 2, column 2 is a 4. (2+2=4)
Row 3, column 1 is a 4.(3+1=4)
Row 3, column 2 is a 5. (3+2=5)

[Daniel55555555]

Oh know.  I am not doing well. So sad

Don't be too concerned, just focus on exam 2 for now.

Yes.i did all the practise one's from 2002-2013. But I only get 72.5% on the first one

The exams from before 2006 are not that relevant any more, I would reccomend looking more thoroughly at the more recent ones.

Thank you. How much study score I can get.if I get 80%for exam 2. My SAC average is 86.7

Predictions are never really accurate, but likely within the range of 35-38.

Their is no logical explanation of why Question 8 Number Patterns wouldn't be A.

Their is no logical explanation of why Question 8 Number Patterns wouldn't be A.

I did not do number patterns for Further maths, and I didn't do the solutions for it as posted on here, but having a look at the notes and the question, my understanding is that a geometric sequence needs to be curved, to show an exponential increase (which would be option B), whereas option A is more of a linear increase.
That's just my quick understanding of it, as I said, I did not do that module.

Yeah but
Distance from x axis is same and this can't be for r less than -1

How do you mean? if it's less than -1 then it can be -2.
its not the distance that matters as we aren't given any numeric values on the graph, it's about the shape of the graph of it switching between positive and negative due r being <-1, it arching because it's a geometric sequence, and lastly it arching away from the x axis because r is not greater than -1 and less than 1. the only graph that fits this description is B

First of all thanks for the answers!
Just wondering what score i need roughly in exam 2 to achieve a study score of 45 I averaged 96% in my sacs and got 38/40 in exam 1 ( did c for 8.Core and D for 7.Networks) . Thankyou!
