Silk Road:
The Silk Road specifically refers to the trading land routes that connects East and Southeast Asia to South Asia and Persia followed by Arabian Peninsula, East Africa and finally Southern Europe.
This network was regularly used from 130 BCE and part of that road is still in existence as a paved highway that connects Pakistan and the Uygur.
Chinese are the one who first started trading in this road and as its name indicates it is mainly used as a trade route for trading silks.
Hence this ancient road played a major role on times when it was constructed.
The 3 factors that improve human capital are education and training,monitoring performances and hiring qualified people.
Answer:
the maximum error in calculating the surface area of the box is 152 cm2
Explanation:
Assuming he dimensions of the box is l, w and h (for length, width and height). The surface area is then: S(l, w, h) = 2lw + 2wh + 2lh = 2(lw + wh + lh)
The change in area can be written as: ∆S ≈ dS = Sl dl + Sw dw + Sh dh
where the partial derivatives are evaluated at l = 80, w = 60 and h = 50, and
dl = dw = dh = 0.2.
The partial derivatives are computed:
Sl = 2(w + h) = 220 Sw = 2(l + h) = 260 Sh = 2(l + w) = 280
Substituting these in for dS,
dS = 220 · 0.2 + 260 · 0.2 + 280 · 0.2 = 152 cm2
