Suppose Cobb-douglus prodution function, yielded 3 = 0.956875 and â = -1.38961 thus the log
form becomes
logQ = -1.38961 + 0.956875 log K +0.429457 log L

T = 90 R = 0.6755 F(2,87) = 117.74 ở = 0.27476
(i) If K is increased by 10 percent while L remains constant,estimate how much Q would increase.
(ii) If all factors pf production (both K and L) are each increased by 10 percent estimate how
much Q would increase.
The structural engineering design section within the engineering department of a regional electrical utility corporation has developed several standard designs for a group of similar transmission line towers. The detailed design for each tower is based on one of the standard designs. A transmission line project involving 50 towers has been approved. The estimated number of engineering hours needed to accomplish the first detailed tower design is 126. Assuming a 95% learningcurve, Solve, a. What is your estimate of the number of engineering hours needed to design the eighth tower and to design the last tower in the project? b. What is your estimate of the cumulative average hours required for the first five designs?
An operation with a learning rate of 0.2 takes 5 hours for the first iteration. How long will it take to complete this task for the 2nd time?

Current engines have an output of 135-hp per engine. 7 years ago, a similar 180-hp engine cost was 4450 KD. Beside that due to extreme competition in the industry, the cost of an engine has decreased with 9% only for 3 intervals of time throughout this period. Total cost consists of engine cost, direct labor cost and other labor-related costs. Pertinent data are as follows: Direct labor cost per hour 20 KD per hour Factory overhead 150% of direct labor Packing costs 80% of direct labor Maintenance costs 10% of engine cost Cost-capacity factor 0.75 Past experience has shown that an 85% learning curve applies to the labor required producing these engines.
