Answer:
21
Step-by-step explanation:
if u divide 649 by 31 u get 20. 93 Wich u round up to 21
To find the derivative, you must use the chain rule.
If u=x^3+2x:
dy/dx=(dy/du)(du/dx)
dy/du=d/du(e^u)=e^u=e^(x^3 + 2x)
du/dx =d/dx (x^3+2x) = 3x^2 + 2
So dy/dx=
e^(x^3+2x) * (3x^2+ 2)
32 is the answer and you write it out by copying what's in the calculator
Answer:
11.3 units
Step-by-step explanation:
Let's find the length of one of the boxes.

Let's simplify c down to 1.41.
Now, there are 8 of these little boxes for the perimeter, let's multiply.

That can be simplified to the nearest tenth - 11.3
Hope this helped!
