QUESTION 4 full question
QUESTION 4 full question
You should have already found the scale factor to be 2.
Then Volume factor = 2^3 = 8.
Divide 1600 by 8 to find the capacity of the smaller container.
For you 'map sizes' question, I don't understand what you want. Can you tell me an example question?
7ci. f(x)=2: Draw the line y=2 on the grid and find the intersection between y=2 and f(x).Can u plz solve Q7,c and d of oct/nov/10 v42
7cii. Find any value of k such that when you draw y=k on the grid, there are three intersection points with the curve f(x).
7d. Draw the line y=5x on your grid and find the intersection points between y=5x and f(x).
Do you mean the gradient question? This has nothing to do with ratio/proportion.
You need to draw a tangent to the curve at x=100 and then find the gradient of this tangent.
This is too much for me to do and I'm not going to draw the graphs for you.
Is there a specific part(s) that you're having trouble with? If the whole question is confusing you then you'll need to revise the methods in your textbook or ask your teacher.
plzz answer the question 5a in the following paper:

First find the length of x using Pythagoras with the lengths 46cm and 24cm.
Then use Pythagoras again to find the diagonal using the lengths x and 20cm.

thnaks alot for the help but 1 small doubt for 7,d i made a line on y=5X but there is only one point intersecting with it can u explain a bit plz

thank you sir i have another question too from the same paper: (q 1d)
There should be 2 intersection points. I would need to see your graph to find your mistake.thnaks alot for the help but 1 small doubt for 7,d i made a line on y=5X but there is only one point intersecting with it can u explain a bit plz

Which part of 1d?
Sorry about that. I can see the picture so I don't know why you can't.
Frequency Density = Frequency / class width
So for 60<t<=80:
Frequency density = 14/20 = 0.7
But the height of this column is 2.8cm so they must be using a scale of 1 unit = 4cm.
Now use the formula again to find the frequency density for the other three intervals then use the scale to find the heights of the columns.
Any time you want but please ask only one question at a time.
