Question 4: The following vectors define the quantity of minerals (in tons) that are extracted from the mines each day. Сopper Titanium Iron Mine 1: U = (400, 1 500, 850) Mine 2: (1 250, 400, 1 000) %3D Mine 3: U = (500, 650, 700) a) Evaluate u +u +us with algebra and explain what the resulting vector represents in this situation. b) Evaluate 14u, with algebra and explain what the resulting vector represents in this situation c) Knowing that the last few extractions lasted 6 days at the mine 1, 7 days at the mine 2 and 12 days at mine 3, calculate the total quantity of minerals mined for each type of mineral (copper, R titanium and iron) by using a linear combination. Give the result in the form of a vector and formulate your answer with a complete sentence. d) How many days must each mine gather resources to gather a total of 17 250 tons of copper, 16 300 tons of titanium and 18 850 tons of iron?
