Answer:
Economical thickness is 3.823 units
<u>Explanation:</u>
Insulation Annual Cost=2000+650t
Energy cost of heat loss=19000*(t) ^ (-0.5)
Total annual Cost=2000+650t+19000t ^ (-0.5)
<u>We need to find optimum value of thickness such that Total annual cost is minimum.</u> Therefore, we have dC/dt=0 and d^C/dt^2>0
Equation 1)
...........dC/dt=650-9500t^-1.5
Equation 2)
...........d^C/dt^2=4750t^-1.5
<u>For 1) </u>we have 650-9500t^(-1.5)=0
650/9500=t^-0.5
190/13=t^0.5
t=3.823 units
Hence, if we check for obtained value of "t" we have second order condition met then
d^2C/dt^2=4750*(3.823)^(-1.5)=635.4584551>0 by the way for any value of "t">0 we will suffice second order condition
Hence, economical thickness is 3.823 units
Answer:
A
Explanation:
Consumer surplus is the difference between the willingness to pay of a consumer and the price of the good.
Consumer surplus = willingness to pay – price of the good
If willingness to pay = price of the good
, then consumer surplus is zero
Answer: Option (D)

Answer:
The debit balance for the vehicles account was $20,000, and the credit balance of accumulated depreciation account was $18,000.
- Dr Vehicles account 20,000
- Cr Accumulated Depreciation Vehicles account 18,000
then the van was sold for $2,000
- Dr Cash account 2,000
- Cr vehicles account 2,000
Since the carrying value of the van was $2,000 (= $20,000 - $18,000) and the van was sold for $2,000, Patel had no gain or loss from this transaction.
Answer: <em>Option (A) is correct</em>
