Afarmer grows a particular plant that has a gene that can be manipulated to control the age t at which the plant matures. the number of seeds s(t) produced by a plant maturing at age t is s(t)=−0.3t2+30t+0.2 seeds per mature plant a farmer asks the geneticists to genetically engineer a plant line that accounts for the fact that on his farm, only p(t)=9t+100, plants mature to age t. what age of maturity should the geneticist select for the plants to maximize the seed production of the farmer's crop? a. between 130 and 140 days b. between 120 and 130 days
