l need the answer in 30 mints please please please.
Ex: The water resources company want to construct (6) pipe culverts of length (8)m to convey irrigation water to an agriculture area. The cost of construction them multiply by (100ID per meter length) contains the following (also per meter length): 1-The excavation works is equal to (30 000)ID, and is varying directly with the square cuivert's diameter. 2- The concrete works is equal to (200 000)ID, and is varying directly with the culvert's diameter. 3- The finishing works is equal to (50 000)ID, and is varying with the inverse of square culvert's diameter. The rate of interest and depreciation for all above costs is (10%). Find the optimal diameter of culverts which gives minimum cost, and then find the total cost of construction them if it contains also (3 million ID) for pavement works over each culvert. ntions are wanted to be used to supply energy.
