- Agriculture At a certain vineyard it is found that each grape vine produces about 10 lb of grapes in a season when about 700 vines are planted per acre. For each additional vine that is planted, the production of each vine decreases by about 1 percent. So, the number of pounds of grapes produced per acre is modeled by An=700+n10-0.01n where n is the number of additional vines planted. Find the number of vines that should be planted to maximize grape production.arrow_forwardLIFE SCIENCE APPLICATIONS Life Span Researchers have estimated the maximum life span in years for various species of mammals according to the formula L(E,P)=23E0.6P0.267, where E is the average brain mass and P is the average body mass both in g. Source: The Quarterly Review of Biology. Find L for the following species. Do these values seem reasonable? a. Black rat, with E=7.35g, P=150g b. Humans, with E=14,100g, P=68,700g c. d.arrow_forward
