Answer:

In the presentation layer of the OSI reference model provides a variety of coding and functions that can be applied in application layer data. Information send by the application layer are ensured by these functions. As, presentation layer is the important layer in the OSI reference model because it is responsible for important services like data compression, data conversion, decryption and encryption.

Encryption at gateway is defined as, when the important data is first encrypted using protocol and then it is transferred in the network. And gateway re-director operates in the presentation layer.

What is the inverse function of d(x ) = -2x - 6?

PtichkaEL [24]

Answer:

$-\frac{x}{2} - 3$

Explanation:

d(x) = -2x - 6

to find the inverse of a function, you need to follow these steps:

1. set d(x) = y

2. interchange the variables, so y becomes x and x becomes y

3. solve the equation for y

step 1: set d(x) = y

y = -2x -6

step 2: interchanging the variables

y = -2x - 6 turns into x = -2y - 6

step 3: solving for y

x = -2y - 6 < add 6 to both sides to get rid of it on the right

x + 6 = -2y < divide both sides by -2 to get y alone

x + 6 / -2 = $-\frac{x}{2} - 3$

-2y / -2 = y

$-\frac{x}{2} - 3$ = y

so the inverse of the function is $-\frac{x}{2} - 3$

Solution:

Guest integration services resolves compatibility issues of certain guest operating systems experiencing non-functioning features.

Data integration service is the employment of a group of services that comply with service-oriented architecture. Data integration service can perform in an N -> 0 latency time period. At the same time, it offers a powerful set of transformation processes for meeting an array of business imperatives. The advantages of employing data integration as an enterprise service include reduced time for marketing, a reduction in total cost of ownership (TCO), and a solution to the obsolete and expensive data-integration patterns presently available in corporate businesses.

This is the required answer.

Assume you have a variable, budget, that is associated with a positive integer. Assume you have another variable, shopping_list,

max2010maxim [7]

Answer:

budget=455

shopping_list=("codelab", "textbook", "ipod", "cd", "bike")

prices={"codelab":300, "textbook":100,"ipod":50, "cd":10, "bike":600}

number_of_items=0

sum=0

for index in range(len(shopping_list)):

sum=sum+prices[shopping_list[index]]

if (sum<=budget):

number_of_items=number_of_items+1

else :

break

print "number of items you can purchase, for a budget of",budget,"is",number_of_items

Explanation:

A code to determine the number of items that can be purchased is above, given the value associated with budget, and given that you will buy items in the order that they appear in the tuple associated with shopping_list.

python (Financial application: compute the future investment value) Write a function that computes a future investment value at

love history [14]

Answer:

def future_investment_value(investment, monthly_interest_rate, years):

print("Years\tFuture Value")

print("- - - - - - - - - - -")

for i in range(1, years+1):

future_value = investment * ((1 + monthly_interest_rate) ** (12 * i))

print(i, "\t\t", format(future_value, ".2f"))

investment = float(input("Enter the invesment amount: "))

interest = float(input("Enter the annual interest rate: "))

year = int(input("Enter the year: "))

future_investment_value(investment, interest/1200, year)

Explanation:

Inside the function:

- In the for loop that iterates through the years, calculate the future value using the formula and print the results

Then:

- Ask the user for the investment, annual interest rate, and year

- Call the function with the given inputs
