To find area, you do length times width. In this case, 5 inches is both the length and width, so you do 5 times 5 and you get 25. 

The answer is 25 in²

D:  We solve this in exactly the same way in which we solved the previous area problem.  Side length is s, area is s^2.  Here, side length is 5 in; area is 25 in^2.
the problem does say, however, not to include units in your answer.  Thus, just write "25."

dusya [7]

Answer:

\frac{dC}{dQ} \approx 1.25, C(101)-C(100) = 1.247, \delta = 0.24\,\%

Step-by-step explanation:

The marginal cost function is:

\frac{dC}{dQ} = 12.5\cdot x^{-\frac{1}{2} }

The marginal cost for 100 books is:

\frac{dC}{dQ} \approx 1.25

The difference is:

C(101)-C(100) = 25\cdot (101^{\frac{1}{2} }-100^{\frac{1}{2} })

C(101)-C(100) = 1.247

The relative error is:

\delta = \frac{|1.25-1.247|}{1.25}\times 100\,\%

\delta = 0.24\,\%
