This assignment challenges you to completely rethink the smartwatch experience for a young and tech-savvy demographic (aged 18-25). Imagine you're a UX designer at a cutting-edge wearables company. Your team is tasked with breathing new life into the smartwatch market by targeting young adults. The goal is to move beyond basic fitness tracking and create a truly innovative and engaging user experience. Tasks: 1. User Requirements: • Explain how you would develop a comprehensive user research plan to understand the desires, frustrations, and overall relationship young adults (18-25) have with wearable technology, particularly smartwatches. • Select and justify three distinct data gathering techniques you would employ in this research phase. • Clearly outline the specific goals you aim to achieve with each technique in the context of understanding young adults and smartwatches. • Explain how each chosen technique would help uncover potential opportunities and challenges for designing a new smartwatch that resonates with this target audience. • Discuss the inherent strengths and weaknesses of each technique. 2. Design Thinking and Ideation: • From what you learned in your user research, apply some design thinking principles. • Brainstorm and develop one or two new concepts for the new smartwatch experience. • Apart from fitness tracking, explore how the smartwatch can seamlessly integrate with the lifestyles and daily routines of young adults. • Sketch (optional), or explain a design concept that focus on different functionalities or user interactions. Briefly explain the rationale behind the concept, highlighting how it addresses user needs and creates a unique value proposition. 3. Testing and Refining (Substitute for Prototyping): • Imagine you have developed a digital mock-up of your chosen design concept. Describe the user testing methods you would employ to assess the usability, appeal, and overall user experience of this concept with the target demographic (18-25 year olds). • Explain how you would analyze the data gathered from user testing to refine and improve your design concept before moving forward to development. 4. Mobile Responsive Website Design: • The development company plans to create a mobile-responsive website to showcase the new smartwatch. Discuss three advantages of using a Post-WIMP approach to the website's GUI design compared to a traditional WIMP approach. Explain how these advantages would make the website more engaging and user-friendly for potential customers who might be viewing it on a tablet or smartphone.

Texts: Use the Inverse Function Property to show that f(x) = 2x - 6 is the inverse of g(x) = 2x + 6. (Simplify your answers completely at each step.) f(g(x)) = 2(g(x)) - 6 = 2(2x + 6) - 6 = 4x + 12 - 6 = 4x + 6 = x, for all x ≠ 0 g(f(x)) = 2(f(x)) + 6 = 2(2x - 6) + 6 = 4x - 12 + 6 = 4x - 6 = x, for all x ≠ -6

1. The International Space Station (ISS) orbits the Earth at 409km above the surface (408km at perigee, and 410km at apogee, so about 409km on average). The Earth's radius is approximately 6, 371km. What is the acceleration due to gravity on the international space station? Does the result surprise you, why or why not?
