Explain the innovation on China car sales due to Covid-19 impact. (40marks)

The development of the internal-combustion engine caused fundamental changes in urban land-use patterns. The transformation from the core-dominated city to the modern suburbanized city took only about 50 years. Given the rapid pace of technological change, it seems likely that some future innovation will cause another transformation of cities. Given your knowledge of science fiction and fact, describe an innovation that would cause fundamental changes in the spatial structure of cities

1. Use the following information from Dell Enterprise to answer the questions.
   

1. Using the Conventional Method, what is the Cost-to-Retail Ratio for 2010? Round to the nearly whole percentage.
2. Using the Conventional Method, what is the ending inventory valued at Cost for 2010?
3. Using the LIFO Retail Method, what is the Cost-to-Retail Ratio for 2010?

In 2010, (when t = 0), the population of a country was 1.16 billion people and increasing at a rate proportional to its population. If the population is measured in billions of people and time is measured in years since 2010, the constant of proportionality is 0.0138.

(a) Define the variables.

Let P be the population, in trillions of people, in year t, where t represents the number of years before 2010.

Let P be the population, in billions of people, in year t, where t represents the number of years before 2010.    

Let P be the population, in billions of people, in year t, where t represents the number of years since 2010.Let P be the population, in billions of people, in month t, where t represents the number of years before 2010.

Let P be the population, in billions of people, in year t, where t represents the current year.

(b) Write a differential equation to describe the relationship.

=

with initial condition P(0) = _____________

(c) Solve the differential equation.
P = _________________________

Compact and analysis conception

1. Are all closed interval compact?

for example [0,1]. are they closed and bounded?

2. If i can find the Maximum and Minimum, does that mean the set is closed and bounded?

• Describe one situation with real-world examples in which a programmer might want to create a loop that tests its condition in the beginning of the loop and one situation in which the condition is tested at the end of the loop.
• There are many situations where infinite loops may occur. Discuss those situations and provide best practices for each of the loop types that help avoid writing infinite loops.

1.) Many languages (e.g., C and Java) distinguish the character ’c’ from the string “c” with separate sets of quotation marks. Others (e.g., Python) use “c” for both single characters and strings of length one. Provide (and justify) one advantage and one disadvantage of Python’s approach.

2.The designers of Java distinguish the primitive types (scalars) from the reference types (all other types of values) in the language. Discuss the costs and benefits to the programmer of this decision

3.In Ruby, the Hash class accepts the “each” method, allowing hashes to be interacted over, like a collection. In Java, however, the Map classes are not formally part of the JCF (Java Collections Framework). For both Ruby and Java, provide (and justify) an advantage of the language’s choice of location in the class hierarchy of its form of associative list

4.What are the basic differences, if any, in how Java and Ruby handle information hiding (a.k.a. encapsulation)?

5. Java and C++ support generic collections with type parameters, whereas Ruby does not. Does that fact place the Ruby programmer at a disadvantage? Why or why not?
