A submersible vessel was

katovenus [111]

Answer:

5.5 meters above start position.

Step-by-step explanation:

-Let X be the start position.

#Total distance below the start position is calculated as:

$d_{down}=6+5.5\times 7\\\\=44.5\ m$

#Total distance above the start position X:

$d_{up}=50\ m$

#Distance above/below start position is:

$d=X-d_{down}+d_{up}\\\\=X-44.5+50\\\\d=X+5.5\ m$

Hence, The vessel is 5.5 meters above the start position

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:

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

$\delta = 0.24\,\%$
