write a function is unique that accepts a dictionary from strings to strings as a parameter and returns true if no two keys map to the same value (and false if any two or more keys do map to the same value).
Answers
By calling this function with a dictionary as an argument, it will return True if there are no duplicate values and False if there are duplicate values.To write a function is_unique that checks if no two keys in a dictionary map to the same value, you can follow these steps:
1. Define the function is_unique that takes a dictionary as a parameter.
2. Create an empty set to store unique values.
3. Iterate through each key-value pair in the dictionary.
4. Check if the value is already in the set of unique values.
5. If the value is in the set, return False, as it means there are duplicate keys.
6. If the value is not in the set, add it to the set.
7. After iterating through all key-value pairs, return True, indicating that all keys are unique.
Here's the code implementation of the function:
```python
def is_unique(dictionary):
unique_values = set()
for value in dictionary.values():
if value in unique_values:
return False
unique_values.add(value)
return True
```

Answers
There have been several cases where private information was disclosed when computer equipment was discarded. One example is the sale of smartphones like BlackBerry without proper data cleansing, which has resulted in personal and sensitive information being accessible to the new owner.
In another case, hard drives were sold without data cleansing after the computers they were originally used in were upgraded. This led to confidential information such as financial records, medical information, and personal photos being exposed to the new owner. Such incidents highlight the importance of data security and proper data cleansing practices before discarding computer equipment.

Which lines of code will assign the discriminant the value b2−4ac? Select 2 options.
discriminant = bb - 4ac
discriminant = b * b - 4 * a * c
discriminant = b ^ 2 - 4ac
discriminant = b ** 2 - 4 * a * c
discriminant = b ^ 2 - 4 * a * c
Answers
Answer:
discriminant = b * b - 4 * a * c
discriminant = b ** 2 - 4 * a * c
Explanation:
The operands are correct and in the right order (for python).
** is the operand for squaring something.
* is the operand for multiplying something.
- is the operand for subtracting something.
Let's take a look at these examples individually.
discriminant = bb - 4ac. You have to use the * sign so the computer understands that you're trying to multiply two objects together.
discriminant = b * b - 4 * a * c. This example works because it's using the * where it's appropriate.
discriminant = b ^ 2 - 4ac. In python we don't use the ^ sign. To use exponents, we use **. Also, there is no * sign in between 4, a, and c.
discriminant = b ** 2 - 4 * a * c. This example works because it uses the ** and * sign where appropriate.
discriminant = b ^ 2 - 4 * a * c. This example uses the ^ sign and python does not support it.

Fear and anxiety are emotions that arise in response to perceived threats or dangers. While Jenna's high-strung nature may cause her to feel anxious or fearful in certain situations, it is not necessarily a direct conflict with her ideal self.

Write down a differential equation of the form dy/dt=ay b whose solutions all approach y=11/10 as t-->
Answers
The differential equation of the form dy/dt = ay-b whose solutionapproach y = 11/10 as t approaches ∞ is dy/dt = 1/10.
How is this so?To find a differential equation of the form dy/dt = ay - b, where the solutions approach y = 11/10 as t approaches ∞,we can set the value of a and baccordingly.
Let's set a = 0 and b = -1/10.
This choice will ensure that the term ay approaches 0 as t approaches ∞, and the term -b approaches 11/10.
Therefore , the differential equation becomes -
dy/dt = 0*y - (-1/10)
dy/dt = 0 + 1/10
dy/dt = 1/10
The solutions to this differential equation will approach y = 11/10 as t approaches ∞.

Answers
During RUN Time, the interpreter changes the source code line by line. A program written in a high-level language is completely translated into machine code using interpret.
While a program is running, evaluation and change are permitted by an interpreter. Instruction by instruction, an interpreter converts code into machine code; the CPU executes each instruction before the interpreter continues on to the next instruction. When a problem arises, interpreted code will immediately display an error, making debugging it simpler than with compiled code. An interpreted language is one in which instructions are executed by implementations without first being translated into machine code. Computed programs execute more quickly than interpreted ones. The compiled program runs faster than the interpreted program.

A(n) ________ must satisfy referential integrity, which specifies that the value of an attribute in one relation depends on the value of the same attribute in another relation.
Answers
A foreign key must satisfy referential integrity, which specifies that the value of an attribute in one relation depends on the value of the same attribute in another relation.
Referential integrity is a condition in relational databases that ensures the consistency and accuracy of data. It enforces the consistency of the relationships between tables by specifying that the value of a foreign key in one table must match the value of the corresponding primary key in another table.
A foreign key is a field in a database table that is related to the primary key of another table. It is used to enforce referential integrity by ensuring that the values of the foreign key in one table match the values of the primary key in another table. This ensures that there are no orphan records or invalid references in the database, which can cause data inconsistencies and errors in applications.
The use of foreign keys and referential integrity is essential in ensuring that data is accurate and consistent in a relational database. By enforcing these constraints, it becomes possible to create complex relationships between tables and ensure that data is organized in a way that makes sense and is easy to query. In conclusion, a foreign key must satisfy referential integrity, which specifies that the value of an attribute in one relation depends on the value of the same attribute in another relation.
