3. (5) the answers to this question must be given on a form, the link to which you have been emailed. consider the following linear programming problem in 3 basic variables, x1, x2, x3, where s1–s4 are slack variables. maximize z = x1 + 0.5 x2 + x3 s. t. -x1 + x2 – x3 + s1 = 2 x1 – x2 – x3 + s2 = 3 -x1 - x2 + x3 + s3 = 1 x1 + x2 + x3 + s4 = 4 x1, x2, x3, s1, s2, s3, s4 ≥ 0 somewhere in the steps of optimization, the objective function can be written as: z = 2x1 + 1.5x2 – s3 + 1 and the constraints can be written as follow: -2x1 + s1 + s3 = 3 -2x2 + s2 + s3 = 4 -x1 – x2 + x3 + s3 = 1 2x1 + x2 – s3 + s4 = 3 a) (2) state what the leaving variable will be. b) (3) determine which will be the entering variable

First to answer all gets a donation question 3(multiple choice worth 1 points) (04.01 lc) which of the following levels is lower than cells in the hierarchy of organization of living things? molecules organs organ systems tissues question 4(multiple choice worth 1 points) (04.01 lc) which of these represents an individual form of life such as an animal, plant, or single-celled life form? organ organism organ system tissue question 5(multiple choice worth 1 points) (04.03 lc) what are the green structures inside plant cells where photosynthesis takes place called? chloroplast mitochondrion nucleus vacuole question 6(multiple choice worth 1 points) (04.03 lc) which of the following best matches a part of a living cell with the function it performs? cytoplasm: fluid which carries the nucleus and other organelles vacuole: fluid which carries the nucleus and other organelles cytoplasm: directs all of the cell's activities vacuole: directs all of the cell's activities question 7(multiple choice worth 1 points) (04.03 mc) read the table below. organelles of plant cells present in both plants and animals present in plants but not animals small in animals but large in plants organelle a organelle b organelle c which statement is most likely correct? organelle a is chloroplast, organelle b is cytoplasm, and organelle c is nucleus. organelle a is mitochondrion, organelle b is cytoplasm, and organelle c is nucleus. organelle a is cell wall, organelle b is chloroplast, and organelle c is mitochondrion. organelle a is mitochondrion, organelle b is chloroplast, and organelle c is vacuole. question 8(multiple choice worth 1 points) (04.03 mc) what will most likely happen in the absence of a nucleus? genetic information will not be transmitted by the cell. energy will not be released during cellular respiration. the cell will not store food, water, nutrients, and waste. the cell will lose its shape and structure.
