Answer:
D. at the intersection of at least two constraints.
Explanation:
Linear programming is an optimization technique which is fine for the purpose of getting the best solution such as maximizing profit or certain o 4th era quantities. It is fine by modelling real life problems into mathematical models that have linear relationships or constraints such as in the form of objective functions. In linear programming, an objective function defines the formula for quantity optimization and the goal from this is to determine variable values that maximize or minimize the objective function depending on the problem robbery solved.
Answer:
First we understand what is hash function.A hash function is mostly used in Hashmaps. It maps different keys to a set of values.There may occur a case when we have same key but different values.This case is called collision.So we have to use different collision handling techniques that are open addressing and separate chaining.
A perfect hash function maps key-value pair such that there are no collisions.

Explanation:
Given
The attached function
What the recursion does is that; it adds up individual digits from N to 0
Solving (a): Each output when N = 6
For N = 6.
The function returns the following values:
f(6) = 6
Then: 6 + f(5)
Then: 6 + 5 + f(4)
Then: 6 + 5 + 4 + f(3)
Then: 6 + 5 + 4 + 3 + f(2)
Then: 6 + 5 + 4 + 3 + 2 + f(1)
Then: 6 + 5 + 4 + 3 + 2 + 1 + f(0)
Then: 6 + 5 + 4 + 3 + 2 + 1 + 0 = 21
Solving (b): The output when N = 7
Using the same process in (a) above.
The output is 28
Answer:
a. Password length, password encryption, password complexity
Explanation:
Under this scenario, the best combination would be Password length, password encryption, password complexity. This is because the main security problem is with the user's passwords. Increasing the password length and password complexity makes it nearly impossible for individuals to simply guess the password and gain access, while also making it extremely difficult and time consuming for hackers to use software to discover the password as well. Password excryption would be an extra layer of security as it encrypts the password before storing it into the database, therefore preventing eavesdroppers from seeing the password and leaked info from being used without decryption.
