The answer is A. when you compress horizontally you take it by a factor of 1/a. in this case a=5. 12 is your k value and k decides whether or not you shift up or down, because k is positive or is upward by 12

If f(x)=(e^(2x)+1)^1/2 then f'(0)=

Kryger [21]

We will first find f ` ( x ) using the chain rule:
f ` ( x ) = $\frac{1}{2 \sqrt{e ^{2x}+1 } } * 2e^{2x} = \frac{e^{2x} }{ \sqrt{e ^{2x} +1} }$
f ` ( 0 ) = $\frac{e ^{0} }{ \sqrt{e^{0}+1 } } = \frac{1}{ \sqrt{2} }$
Answer: f ` ( 0 ) = 1/√2 ( or: √2/2 )

Here’s what you can do to make this very simple. Consider that the “missing” space between the rectangles isn’t there. Then, find the area:

10 x 9 = 90 mm

Now, find the area of the “missing” part.

5 x 2 = 10 mm

Finally, you deduct the missing part from the complete rectangle!

90 - 10 = 80 mm

The area of this whole thing is 80 mm!
