Answer:
(b)False
Explanation:
defined as
=
Where x is the distance from centroidal x-axis
y is the distance from centroidal y-axis
dA is the elemental area.
The product of x and y can be positive or negative ,so the value of can be positive as well as negative .
So from the above expressions we can say that the product of 
is different from .
It can provide measurements of stars with a higher angular resolution than is possible with conventional telescopes.
Cadastral surveying is the sub-field of cadastre and surveying that specialises in the establishment and re-establishment of real property boundaries. ... A cadastral surveyor must apply both the spatial-measurement principles of general surveying and legal principles such as respect of neighboring titles.
Answer:
a. 78.4 pieces/hr
b. $0.1806/min
c. $1.34/piece
Explanation:
(a) With a cycle time Tc = 45 sec = 0.75 min.
Production rate, Rp = 60/0.75 = 80 pieces/hr.
Let us factor in the 98% proportion uptime, so Production rate, Rp = 0.98*(80) = 78.4 pieces/hr
Quantity of product annualy = 6000 *(78.4) = 470,400 pieces/yr
(b) Equipment cost rate, Ceq = 500,000(1.30)/(60 x 10 x 6000) = $0.1806/min.
(c) Cost per piece of mould, Ct = 100,000/1,000,000 = $0.10/piece
Cost rate of labour ,CL = 18.00(0.20) = $3.60/hr = $0.06/min
Conclusively, cost per piece, Cpc = 1.20(0.88) + (0.06 + 0.1806)(0.75) + 0.10 = $1.34/piece
