Answer:
70.71m
Step-by-step explanation:
In order to find the diagonal, we can use Pythagiras theorem by splitting the field in half and creating a right angled triangle.
A^2+B^2=C^2
50^2+50^2=C^2
5000=C^2
Square root 5000= 70.71m (2dp)
Hope this helped!
The linear approximation means that you assume the function is linear. So, just do :
f(5) + f'(5) (x-5)
This works out, in this specific case
3 + 4 (- 0.2)

If Melanie get's 4.10$, then Jacob get's 20.50$.
We can divide to get the unit rate:
20.50 ÷ 4.10 = 5
This means that if Jacob gets 5$, then Melanie will get 1$.
So in this case, Melanie get's 1$.
Answer: $15,000
As $35,000-$20,000=$15,000.
That's basically the profit he had made, or the return on his investment (ROI).
As he already had $20,000, he had "only" made $15,000.
