Dot Notation can be used with lower(), upper() or str() string methods. true or false
The statement is true; dot notation can indeed be used with the lower(), upper(), or str() string methods to manipulate strings in programming.
Explanation:The statement that Dot Notation can be used with lower(), upper(), or str() string methods is true. Dot notation is a syntactic form that allows access to an object's properties, functions, or methods. In the context of string manipulation in programming languages such as Python, when you have a string object, you can apply various methods to it using dot notation.
For example, the lower() method can be used to convert all characters in a string to lowercase. Similarly, the upper() method converts all characters to uppercase. The str() method is often used to convert a non-string object to a string.
Here's how they can be used in practice:
my_string.lower() - Turns all characters in my_string to lowercase.my_string.upper() - Converts all characters in my_string to uppercase.str(my_object) - Converts my_object (which could be any type of object like an integer or a float) to a string format.What are the two main purposes of S/MIME?

Show two ways of bracketing an exposure of f/16 at 1/125 shutter speed. (Copy the two lines below and fill in the blanks for the two alternate exposures for each way. Remember that you need an f-stop and a shutter speed to write an exposure.)
Answer:
Explanation:
If we use bracketing, we must take three pictures of the same place, but we must take it with different exposures.
In this particular example we have an exposure of f/16 at 1/125 shutter speed, first we must take underexposed picture with exposure of f/22 at 1/125 shutter speed or exposure of f/16 at 1/400 shutter speed, then we take an overexposed picture with exposure of f/8 at 1/125 shutter speed or exposure of f/16 at 1/50 shutter speed.
The last step is taking the three pictures and use the option bracketing in an editing photo tool, there are cameras that have this option to take 3 pictures automatically.
The ____ term implies that the type’s data can be accessed only through methods.
A. abstract type library
B. advanced data type
C. abstract definition type
D. abstract data type
Answer:
D. abstract data type
Explanation:
Abstract data type is a data type whose implementation is embedded behind an abstraction. They can be worked via methods and functions but their specification is abstracted.
Lists and Stacks can be given as examples of abstract data types.
Abstract data type can be considered as the opposite of Concrete Data Type (CDT).
Final answer:
The abstract data type (ADT) is the correct term that refers to a type where its data is accessible only through specific methods, providing encapsulation of data.
Explanation:
The abstract data type (ADT) term implies that the type’s data can be accessed only through methods. This encapsulates the data and only allows it to be accessed or manipulated through a defined set of operations. ADTs provide a mathematical model for data types where data and operations are defined independently of any specific implementation.
This abstraction allows for different implementations that can vary internally but share the same external interface. An example of an ADT is a stack, which provides operations such as push, pop, and peek without revealing the underlying data structure, whether it be an array, list, or any other method of internal representation.
