Ban serine 50.800 yards por week in his practices. Given this amount of isining, he will swim the 100-yard butterfly in 54 1 seconds and place With in a big upcoming ment. Ban's coach calculates that if Bon Increases his popdice in 60,900 yards per week. his time will decrease to 40. 5 seconds and he will place $th in the meet. I Den practices 70 030 yards per week, his time will be 47 1 seconds and he will win the ment In forms of Don's time in the big must, what is his marginal producivity of the number of yards he practices? The marginal product of increasing practice yards from 50.000 to 60 009 is | ] secondsj center a numeric response using a real number rounded to one decimal place), and the marginal product of Increasing practice yards from 60,008 to 70 000 is [ ] seconds) Is there diminishing marginal productivity of practice yards? In terms of Ban's place in the big meet what is his marginal productivity of the number of yards he practices? The marginal product of increasing practice yards from 50,000 to 60 009 is | ] place(s], and the marginal product of increasing practice yards from 60,030 to 70,000 is |]placesj In there diminishing marginal productivity of practice yards? Does Ben's marginal productively of the number of yards he practices depend on how he measures his productivity other place or time, In the big mast? Given a Cobb-Douglas production function where a = $ = 0.5: Q = (10.5) x (L0.5) Find the equation for the isoquant when Q = 2,000. OA. [2,000 ) 0.5 OB. 2.000) 2 K = 2 K = 0.5 OC. OD.
