guys its 2/8(1/4), because its the whole venn diagram and the notation is subset which is C, guys what about the surface area, almost alllllll my friends got 768.

paper 22
I got 576 ..... K^3 = 64/27 ..... k=4/3 ..... k^2 = 16/9
`````9/16 * 1024 = 576

q had 3 elements
qnp had 2 elements so 2/3

Question, were you suppose to write the number of elements or the letters?

Was the last answer subset(C) or belongs to(similar to E)

How to remember the shear and stretch matrices easily

 

[dubi2pro]

the (b) parrt please!

 

[Evangeline]

the (b) parrt please!

First start by substituting g(x) instead of x in the equation f(x) so you end up with:
Fg(x)= (2x+7)^2 + (2x+7) -3
=(4x^2+30x+53)
So P=4
Q=30
R=53
Please check the answer from the markscheme for reassurance, hope this helped

 

[Evangeline]

I checked it from the mark scheme and it's correct hope you got it

I don't know if I can help because I don't know what the topic is about but in general articles address certain main points and to ensure you have a good article you my find it helpful to include these points:
Start with a brief description on the topic in your introduction and make sure to state your point of view on which you'll base the rest of your article on.
Then, start a paragraph in the body with a main idea and expand by giving examples, explanation or even anecdotes (depending on the topic). The number of paragraphs to be written in the body is decided by you (or preset) , make sure each has this format.
The conclusion should sum up your opinion along with another reason to why it's valid to support it.
Make sure you write consistently with minimal grammatical and spelling errors. Avoid using indefinite or personal pronounce like you or us without linking them to a known antecedent. Make sure that your article lies within the word limit and covers the topic through assessing several aspects.
Best of luck , hope this was a bit helpful.
