# Reviewing Potential Errors

Hi,

I was wondering if anyone is able to check over a major assignment I have completed, and point out any errors I may have made. I am fairly confident it is all correct, but if someone can give it another once over that would be great. If you're not able to do this, is it okay if you can check over 2e), 6c) and 5f) at least. The questions follow along with each other, so I have attached a link with each page of the assignment (it is six pages long) that will open in another browser.

With 2e) - I have written that it is reflected on the x-axis. Is this the correct terminology, or would it just be "on its axis"?

With 5f) - I am new to using derivatives so am not sure on this one.

With 6c) - I am concerned whether the answer is either 113.2m or 113.3m. I put 113.3m, but this is with using the previously rounded values in my distance formula. Would I have to use the original non-rounded values in it for it to be correct?

Greatly Appreciated and Kind Regards ,

Please find a way to communicate. We like having hard-working students, here.

2e: The entire graph is not reflected over the x-axis; and the graph itself doesn't have an axis. You'll have to find a different way to describe the axis, or what happens.

6c: Why use the distance formula for the length of a horizontal line? Just subtract, and you get 113.3. But in general, don't round values in the middle of your work. (I didn't check whether your x-coordinates are correct.)

I don't feel like reading through the whole thing, parts of which are hard to read. I'll let others do that if they want to. In the future, just ask one question at a time, and don't submit pdfs.

Hi there,

I am not sure why the link is not working? What happens when you click on the link exactly?

Thanks

Emphasis on the "It's possible...". Not every installation, or browser, or firewall is the same. If you submit one problem at a time, in the native language, there is never a problem.
