Suppose the cost of publishing x books is C(x) = 10000 + 25<img src="https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D" id="TexFormula1" ti
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\,\%

What is the equation in point-slope form of the line passing through (2, 5) and (−1, 8)?
julsineya [31]
(2,5)(-1,8)
slope = (8 - 5) / (-1 - 2) = 3/-3 = -1

y - y1 = m(x - x1)
slope(m) = -1
(2,5)...x1 = 2 and y1 = 5
now we sub
y - 5 = -1(x - 2) <==
