Linux is a desktop environment that can be used with several different operating systems.

PROBLEM 1: Transportation engineers analyze population growth trends separately for a city and its adjacent suburb to plan future infrastructure projects, such as roads and public transit. You have been given population data for the city and suburbs from 2000 to 2025 at five-year intervals.   Year City Population (thousands) Suburb Population (thousands) 2000 450 150 2005 490 180 2010 520 220 2015 540 280 2020 560 340 2025 590 420 Create a chart in Excel comparing the population trends of the city and suburb from 2000 to 2025. Include axis labels, a title, and a legend identifying the two data sets. Add a trendline to each set of data, select the equation that in your opinion is the best fit for each set. Use the equations to predict future populations, as an example forecast the population in 2030. If current trends continue, in what year will the suburb’s population surpass the city’s population?

PROBLEM 2: In municipal water supply systems, engineers must calculate flow rates in interconnected pipes to ensure adequate pressure and delivery. Consider a pipe network with four interconnected pipes with unknown flow rates Q1, Q2, Q3, and Q4. Conservation of mass and conservation of energy principles enforce the water supply system to satisfy the following set of linear equations: Use Excel to write the coefficient matrix and right hand side vector for these set of linear equations. Determine the inverse of the coefficient matrix. Find the solution for the flowrates Q1, Q2, Q3, and Q4 that satisfy the equations using the inverse matrix method. Use Solver to find the solution for the flowrates Q1, Q2, Q3, and Q4 that satisfy the equations. Select the last equation as Objective and the other three equations as constraints. Compare your solution to the one in part C. SAVE YOUR EXCEL FILE AND CONTINUE TO THE NEXT PROBLEM

BCH4024 070125 OC Su25 E2 Q33: You see a patient in your clinic that is severely sick and reveals that they have eaten a meal that contained fermented coconut. You remember from your biochemistry days that a toxin, bongkrekic acid, is produced by a contaminating bacterium in fermented coconut and corn. This toxin specifically inhibits adenine nucleotide translocase. Which consequence is most likely associated with the inhibition of adenine nucleotide translocase in human cells?

BCH4024 070125 OC Su25 E2 Q27: You isolate mitochondria from a patient with severe fatigue and muscle cramps. You determine that the patient is unable to 1) oxidize succinate, and 2) reduce ubiquinone. This patient most likely suffers from a defect in which of the following protein complexes?

BCH4024 070125 OC Su25 E2 Q45: An 18 year-old individual who was working in a ship for a pest control company using cyanide-containing pesticides presents to the emergency department with general weakness and malaise.  He has a fast heart rate, and complains of severe headache, abdominal pain, and shortness of breath.  The poison in the pesticide that this individual was using inhibits most directly which of the following processes?
