It would take Carl 3.6 minutes and it would take Thomas 1.2 minutes.
The page is 12 inches wide. He wants to center the photo that is 3 1/2 inches wide. So, you do 12 - 3 1/2 (3.5), which equals 8.5. Then, because the page has 2 sides (obviously), you do 8.5 ÷ 2, so your answer is 4.25 (4 1/4) :)
P.S you are not stupid :)

Answer:</h3>
0.225
<h3>
Step-by-step explanation:</h3>
The mnemonic SOH CAH TOA reminds you of the definition of the tangent of an angle.
... Tan = Opposite/Adjacent
The side opposite angle C is AB. The side adjacent to angle C is BC. Then ...
... tan(C) = AB/BC = 18/80 = 0.225
No, it is not.
Hope this helped :)
When integrating,
u-substitution is used to make things easier to work out. In u-substitution, the "u" is generally determined if its derivative is in the expression. That way when integrating with respect to "u", you can just replace the derivative of the u with "du" and easily integrate.
For this question, it would be easiest to let:
Let's take the derivative of u and see if we can work something out:
We have an x² in the integral expression, and therefore, it's valid for us to let
u = 2x³.
Thus, your answer is A.
