Yeah it is really impressive stuff, and so nice to use as well (Yes) Thank you guys once again for your help with my question, I really do appreciate you taking the time to explain things so clearly :D Have a great day! (Yes)

Hi MarkFL, That is genius, thank you so much! :D I will have a play around with this Desmos tool, it's excellent isn't it (Yes) Before I read your reply, I had a quick test of another graphing tool and got the following result: Not as neat as Desmos but still useful :cool:

Hi MarkFL, Great! :D Ok so the last thing I need to work out now is how to show that using the Desmos graphing tool. Now I know how to plot two points on a piece of graph paper, but I haven't quite figured out how to do it on there (haven't had my coffee yet so I'm not fully alert, lol)...

Hi Jameson and MarkFL, Once again thank you very much for your help here, greatly appreciated! :D The Desmos graphing tool is excellent and is just what I'm looking for (Yes) Ok so if the left end point is (15,150000), then I think I have calculated the right end point to be: When t=35...

Hi MarkFL, Thank you for the reply :-) Ah I see, is that similar to plotting coordinates then? I'm still a bit unsure of how to plot them, but I understand the concept :-/ Also I would like to draw the graph using a graphing calculator online, does that make things a bit trickier? Thank you...

Hey guys, In the image below, I understand that the equation is a linear function, but I am unsure how to graph it and present it in the way requested :confused: For those who cannot see tinypic images: Draw the graph of $s=1400(t-15)+150\,000$ Put $s$ on the vertical axis and cover the...

Hi guys, This question has me a bit stumped and I can't seem to find any methods on Google that would help me solve this: The last part of the question asks me to find the value of the scale factor, which in this equation I believe is 1.8. I know how to calculate percentage increases the...

Hi earboth, Thank you and the other posters for your help with my formula. I am very very grateful! :cool: Have a great day :D

Thank you so much earboth, for checking out my work and also pointing that last line out. I will blame user error :-D Corrected: Hopefully that should do the trick :-)

Hi guys, So after taking a break from this and then going back to it, here is my attempt:How does it look? :-/ Thanks guys :-)

Hi ProveIt. Many thanks for your helpful reply :D Ok so given what you pointed out, I would say that I need to convert the length in meters to centimeters and then divide by 50, which would give the model length to be around 29.34cm?

Hi guys, I need to figure out the length of the side of a roof on a scaled down model. The picture below shows what I’m trying to calculate. The real house has a central support pole and it is 10 metres high, with length of the side of the roof at 14.67… metres. If I was to make a scaled...

Hi guys, Many thanks for the replies! :-D I am currently having another look at where I went wrong, I do struggle with these sorts of questions :-(

Hey guys, I have made an attempt at rearranging the formula below and I am looking for someone to just have a look over it and see if I got it right?Really appreciate any pointers or tips Thank you! :-)

Excellent! :D Thanks again for all your help, I am very grateful of helpful people like you sir. Keep up the good work!
