surface area is the area of all the faces on a shape so to speak.
2(120 x 110)=26,400
2(120 x 4)=960
2(110 x 4)=880
880+960+26,400=28,240
Surface area = 28,240
I’ve never done a tape diagram before (so this might be wrong). But I think it’s:
6t=9
If this is correct, I hope it helps :)
Answer:
we have to see question 1 to help with number two
Answer:
Fourth term: 
= 
= 
Fifth term: 
= 
= 1
Sixth term: 
Step-by-step explanation:
The geometric progression is:
The first term, a, is 9
To find the common ratio, r, all we have to do is divide a term by its preceding term.
Let us divide the second term by the first:
That is the common ratio.
Geometric progression is given generally as:
where a = first term
r = common ratio
= nth term
We need to find the 4th, 5th and 6th terms.
Fourth term: = =
Fifth term: = = 1
Sixth term:
Yeah. You basically have to look at every x value and see if for every x value, is there ONLY one y-value. So in your example, it is a function because every x value has only one y value. Let’s say you had (1,3) and (1,5). That would not be a function because the x value of 1 has TWO y values (3 and 5), therefore it is not a function.
That’s how you can easily spot if something is a function by just looking at a handful of ordered pairs. I hope this makes sense.
