Need help with my home work I’ll upload the file and if you have any questions please ask

PART 1: Answer these questionsA box is to be constructed from a sheet of cardboard that is 20 cm by 60 cm, by cutting out squares of length x by x from each corner and bending up the sides. What is the maximum volume this box could have?Find the amplitude and period of y = –3cos(2x + 3). Use your calculator to graph the function and state its symmetry.Find the first positive x-intercept using your calculator’s zero function. Find two functions f(x) and g(x) such that f[g(x)] = x but g[f(x)] does not equal x. State the vertical, horizontal asymptotes and zeros of the rational function, f(x) = x2+3x+2x2+5x+4.Why is there no zero at x = –1? Give an example and explain why a polynomial can have fewer x-intercepts than its number of roots.PART 2: Over the course of this unit, what concept did you find the most challenging? What did you do to clarify this concept and further your learning? Please explain the concept and give at least one real world example that demonstrates the concept that you have selected. Your response must be at least three paragraphs.Units were: 01.02 Introduction to Calculus 01.03 Review of Function Terminology and More 01.04 Graphing Calculators 01.05 Compositions and Transformations of Functions01.06 Some Common Functions

Module addresses the following aspects: Model a decision situation under risk using a decision tree and use this method to make the best-informed decision, Use Bayes’ Theorem to determine a posteriori decision probabilities.Case---instructions attached Set up a decision tree to model a decision under Risk.Use a decision tree model to determine the best alternative.Perform sensitivity analysis using a decision tree model.SLP---instructions attachedUse Bayes’ Theorem to determine a posteriori decision probabilities.Utilize a decision tree to model the value of information.Determine if the information from an expert is worth the cost.Develop a professional PowerPoint Presentation.Discussion----instructions below (1 page)Do some research on recent trends in business analytics such as Google Analytics, cloud computing, artificial intelligence, machine learning and so on.Focus on one trend and discuss its relevancy to your business or any business you would like to discuss.Consider how these analytics tools would impact business decision making.Week 1: Provide your initial discussion post to the question. Be sure to include references to any resources you used. You should use at least one resource to help you with your initial discussion.
