Answer:
many forms
Explanation:
Polymorphism is a construct in object oriented programming which means multiple forms.For example: Suppose I have a function which performs the add operation on two integers and another function with the same name which concatenates 2 given strings:
- string add ( string a , string b)
The two functions represent polymorphic forms of the add function. The function to be invoked at runtime is determined by the runtime argument type.
For example , add (2,3) will invoke int add ( int a, int b);
Similarly, add("hello","world") will invoke string add ( string a , string b);
Answer: A.The introduced species compete for resources more effectively than native species.
Explanation:
An introduced species is also called the exotic species and this is an organism which is not a native organism or specie and therefore isn't native to the place but rather it's being transported to the place through the activities of human being.
When the introduced species are introduced to a particular area, they compete with the natives for the available resources and often do this more effectively than the other native species.
Therefore, the correct option is A.
Answer:
miles_gallon = float(input("Enter car's miles/gallon: "))
dollars_gallon = float(input("Enter gas dollars/gallon: "))
print("Gas cost for 20 miles is $", (20 / miles_gallon) * dollars_gallon)
print("Gas cost for 75 miles is $", (75 / miles_gallon) * dollars_gallon)
print("Gas cost for 500 miles is $", (500 / miles_gallon) * dollars_gallon)
Explanation:
*The code is in Python.
Ask the user to enter the car's miles/gallon and gas dollars/gallon
Calculate the gas cost for 20 miles, divide 20 by miles_gallon and multiply the result by dollars_gallon, then print it
Calculate the gas cost for 75 miles, divide 75 by miles_gallon and multiply the result by dollars_gallon, then print it
Calculate the gas cost for 500 miles, divide 500 by miles_gallon and multiply the result by dollars_gallon, then print it

A Uniform Resource Identifier (URI) is a compact sequence of characters that identifies an abstract or physical resource.
The statement that combinations of spaces and special characters can be used in domain names of uniform resource locators (URLs) is false. Correct answer: B
The specifications for URLs are clealy defined by
The Internet Engineering Task Force (IETF).
