A factory has production function Q = f(L, K). In year 1: 212 = f(78, 144) In year 5: 309 = f(117, 216) This production function displays increasing returns to scale. True False

Please indicate which multiple choice awnser is correct for question 1.1)1.2)1.3)Please indicate it correctly as I have had this awnsered with different letters to the awnser I was told   1.1 - A firm trebles its inputs and discovers that its output rises by a factor of four. This is an example of;Select one or more:a. constant returns to scaleb. diminishing returns to a variable factor c. increasing returns to scaled. economies of scale1.2 - Diseconomies of scale are present when.... Select one or more:a. marginalcostsriseb. long run average costs rise as output rises c. totalcostsfallasoutputrisesd. total costs rise as output rises 1.3 - If the demand for a firm’s product is price inelastic, this implies that Select one or more: a. price changes have no impact on quantity demandedb. a fall in price of 3% will lead to a decline in quantity demanded of more than 3%c. a rise in price will raise total expenditure on the goodd. a 5% rise in price will result in a fall in quantity…

Assume a Cobb-Douglas production function of the form: 3 What type of returns to scale does this production function exhibit? In this instance, returns to scale equal This production function exhibits q=10L0.28K0.59 (Enter a numeric response using a real number rounded to two decimal places.) OA. increasing returns to scale. OB. constant returns to scale. OC. initially decreasing but then constant returns to scale. O D. decreasing returns to scale. O E. initially constant but then decreasing returns to scale.

What is the optimal productivity rate for a two-person carpentry crew that has a measured productivity of:y = -6.18x2 + 4.326x + 4.516   Answer is 14 hours but how do i get that.
