53. An industrial psychologist conducts two efficiency studies atthe Chilco appliance factory. The first study indicates that theaverage worker who arrives on the job at 8:00 A.M. will haveassembled-' + 6r² + 13tblenders in t hours (without a break), for 0 < t < 4. Thesecond study suggests that after a 15-minute coffee break, theaverage worker can assemble- + + 251blenders in t hours after the break for 0 < t < 4. Note: The15-minute break is not part of the work time.a. Verify that if the coffee break occurs at 10:00 A.M., the av-erage worker will assemble 42 blenders before the breakand 49 blenders for the two hours after the break.b. Suppose the coffee break is scheduled to begin x hours af-ter 8:00 A.M. Find an expression for the total number ofblenders N(x) assembled by the average worker during themorning shift (8 A.M. to 12:15 P.M.).c. At what time should the coffee break be scheduled so thatthe average worker will produce the maximum number ofblenders during the morning shift? How is this optimumtime related to the point of diminishing returns?

In a previous question, I had found that I would need 43.5 ounces of beet seed to plant in 3 - 580 foot beds that has five rows of beets each and a planting rate of 0.5 oz of beet seed per 100 feet of row Beets will typically yield one bunch for every 18” of row. If you can sell the bunched beets for $1.50 per bunch, what would be your gross income from the 3 beds? If the beds are on 6-ft centers, what would be the approximate gross income per acre for the beets?

A manufacturer producing a new product estimates the annual sales to be 9600 units. Each year, 8% of the units that have been sold will become inoperative. So, 9600 units will be in use after 1 year, [9600 + 0.92(9600)] units will be in use after 2 years, and so on. How many units will be in use after n years?
