Your IaaS cloud company has announced that there will be a brief outage for regularly scheduled maintenance over the weekend to apply a critical hotfix to vital infrastructure. What are the systems they may be applying patches to

Answers

Answer 1

Answer: Load Balancer

Hypervisor

Router

Explanation:

The systems that they may be applying the patches to include load balancer, hypervisor and router.

The load balancer will help in the distribution of a set of tasks over the resources, in order to boost efficiency with regards to processing.

A hypervisor is used for the creation and the running of virtual machines. The router helps in the connection of the computers and the other devices to the Internet.

The compound known as butylated hydroxytoluene, abbreviated as BHT, contains carbon, hydrogen, and oxygen. A 1.501 g sample of BHT was combusted in an oxygen rich environment to produce 4.497 g of CO2(g) and 1.473 g of H2O(g). Insert subscripts below to appropriately display the empirical formula of BHT.

Answers

Answer:

C15H24O

Explanation:

n(C) = 4.497 g/44g/mol = 0.1022

Mass of C = 0.1022 × 12 = 1.226 g

n(H) = 1.473g/18 g/mol = 0.0823 ×2 moles = 0.165 moles

Mass of H = 0.0823 × 2 ×1 = 0.165g

Mass of O= 1.501 -(1.226 + 0.165)

Mass of O= 0.11 g

Number of moles of O = 0.11g/16g/mol = 0.0069 moles

Dividing through by the lowest ratio;

0.1022/0.0069, 0.165/0.0069, 0.0069/0.0069

15, 24, 1

Hence the formula is;

C15H24O

Answer

The formula is C1SH240

The following pseudocode describes how a widget company computes the price of an order from the total price and the number of the widgets that were ordered. Read the number of widgets. Multiple the number of widgets by the price per widget of 9.99. Compute the tax (5.5 percent of the total price). Compute the shipping charge (.40 per widget). The price of the order is the sum of the total widget price, the tax, and the shipping charge. Print the price of the order

Answers

Answer:

The program in Python is as follows:

widget = int(input("Widgets: "))

price = widget * 9.9

tax = price * 0.55

ship = price * 0.40

totalprice = price + tax + ship

print("Total Price: $",totalprice)

Explanation:

The question is incomplete, as what is required is not stated.

However, I will write convert the pseudocode to a programming language (in Python)

Get the number of widgets

widget = int(input("Widgets: "))

Calculate price

price = widget * 9.9

Calculate the tax

tax = price * 0.55

Calculate the shipping price

ship = price * 0.40

Calculate the total price

totalprice = price + tax + ship

Print the calculated total price

print("Total Price: $",totalprice)

How are dates and times stored by Excel?​

Answers

Answer:

Regardless of how you have formatted a cell to display a date or time, Excel always internally stores dates And times the same way. Excel stores dates and times as a number representing the number of days since 1900-Jan-0, plus a fractional portion of a 24 hour day: ddddd. tttttt

Explanation:

mark me as BRAINLIEST

100 %sure

Dates are stored as numbers in Excel and count the number of days since January 0, 1900. Times are handled internally as numbers between 0 and 1. To clearly see this, change the number format of cell A1, B1 and C1 to General. Note: apparently, 42544 days after January 0, 1900 is the same as June 23, 2016

The _________ attack exploits the common use of a modular exponentiation algorithm in RSA encryption and decryption, but can be adapted to work with any implementation that does not run in fixed time.
A. mathematical.
B. timing.
C. chosen ciphertext.
D. brute-force.

Answers

Answer:

chosen ciphertext

Explanation:

Chosen ciphertext attack is a scenario in which the attacker has the ability to choose ciphertexts C i and to view their corresponding decryptions – plaintexts P i . It is essentially the same scenario as a chosen plaintext attack but applied to a decryption function, instead of the encryption function.

Cyber attack usually associated with obtaining decryption keys that do not run in fixed time is called the chosen ciphertext attack.

Theae kind of attack is usually performed through gathering of decryption codes or key which are associated to certain cipher texts

The attacker would then use the gathered patterns and information to obtain the decryption key to the selected or chosen ciphertext.

Hence, chosen ciphertext attempts the use of modular exponentiation.

Write a method that prints on the screen a message stating whether 2 circles touch each other, do not touch each other or intersect. The method accepts the coordinates of the center of the first circle and its radius, and the coordinates of the center of the second circle and its radius.

The header of the method is as follows:

public static void checkIntersection(double x1, double y1, double r1, double x2, double y2, double r2)


Hint:

Distance between centers C1 and C2 is calculated as follows:
d = Math.sqrt((x1 - x2)2 + (y1 - y2)2).

There are three conditions that arise:

1. If d == r1 + r2
Circles touch each other.
2. If d > r1 + r2
Circles do not touch each other.
3. If d < r1 + r2
Circles intersect.

Answers

Answer:

The method is as follows:

public static void checkIntersection(double x1, double y1, double r1, double x2, double y2, double r2){

    double d = Math.sqrt(Math.pow((x1 - x2),2) + Math.pow((y1 - y2),2));

    if(d == r1 + r2){

        System.out.print("The circles touch each other");     }

    else if(d > r1 + r2){

        System.out.print("The circles do not touch each other");     }

    else{

        System.out.print("The circles intersect");     }

}

Explanation:

This defines the method

public static void checkIntersection(double x1, double y1, double r1, double x2, double y2, double r2){

This calculate the distance

    double d = Math.sqrt(Math.pow((x1 - x2),2) + Math.pow((y1 - y2),2));

If the distance equals the sum of both radii, then the circles touch one another

    if(d == r1 + r2){

        System.out.print("The circles touch each other");     }

If the distance is greater than the sum of both radii, then the circles do not touch one another

   else if(d > r1 + r2){

        System.out.print("The circles do not touch each other");     }

If the distance is less than the sum of both radii, then the circles intersect

   else{

        System.out.print("The circles intersect");     }

}
