Concept explainers
Radioactive decay of radioactive materials can be modeled by the equation A = A0e−t(log 2/h), where A is the amount of the material at time t, A0 is the amount at time 0, and h is the half-life.
Technetium-99 is a radioisotope that is used in imaging of the brain. It has a half-life of 6 hours. Your

- Welcome to the era of Aladdin and the great magic lamp. This is 1st of January and Aladdin will be in jail for one year. He was recently caught for helping forty thieves. Now he has nothing to do. But he knows that Jasmine is waiting for him. At some point he got an idea to give Jasmine a magical program that can find intervals of months from a year. This allows her to easily determine how long it will take for Aladdin to get out. Then Aladdin rubs the magic lamp and The Genie appears. Then he asked The Genie to make such a magical program. Unfortunately the Genie doesn't know programming and he wants your help to create that magical program. Genie will give you N as the day of the year and you have to print in which month that day is. Input Format Input will contain one line with a single integer N, day of the year. Constraints 1 <= N <= 365 Output Format Print a single line containing the name of month. Be careful about the newline ('\n') at the end.

They are exhibiting this amoeba in a national. conference. They want to know the size of the amoeba at a particular time instant. If a particular month's index is given, write a program to display the amoeba's size. For Example, the size of the amoeba on month 1, 2, 3, 4, 5, 6,... will be 0, 1, 1, 2, 3, 5, 8.... respectively.arrow_forwardThe Harris-Benedict equation estimates the number of calories your body needs to maintainyour weight if you do no exercise. This is called your basal metabolic rate, or BMR.The formula for the calories needed for a woman to maintain her weight isBMR = 655 + (4.3 x weight in pounds) + (4.7 x height in inches) -(4.7 x age in years)The formula for the calories needed for a man to maintain his weight isBMR = 66 + (6.3 x weight in pounds) + (12.9 x height in inches) -(6.8 x age in years)A typical chocolate bar will contain around 230 calories. Write a program that allows the userto input his or her weight in pounds, height in inches, age in years, and the character M formale and F for female. The program should then output the number of chocolate bars thatshould be consumed to maintain one's weight for the appropriate sex of the specified weight,height, and age.arrow_forward
- Easy Program Please answer fast: you will write a program that calculates the area for ANY regular polygon. Ask the user for the side length of the polygon (the type should be double) and the number of sides (the type should be int). The formula for calculating the area can be seen below and comes in three parts. First, calculate the perimeter of the polygon: given:- perimeter(reg_polygon)=slen*nsidesarrow_forwardA very known application in natural language processing is to extract information from a given text. In this lab, you will be able to extract some emotions (Sad and Happy) from a given string and calculate the score of each emotion. You will be given below the words that express sadness, anger, and happiness. For each word, you will be given weight as well, so that when you are calculating for example the score for sadness in the text (string), you can use this formula:arrow_forwardWrite a program that calculates the equivalent resistance of a circuit. n electrical resistors with resistance values R1, R2,.., Rn are said to be connected in parallel if the same voltage is applied across each. Their equivalent resistance Reg is related to the values R1, R2, ..., Rn by: 1 1 1 1 + +...+ R R R, R. "eq Write a program that prompts the user to enter the resistance of n resistors. The user should be prompted continuously by using a while loop until a zero or negative value is entered (the program should count the number of resistors n entered by the user and store the values in an array). Use another separate loop to print the resistance values entered by the user and the equivalent resistance Reg. Test your program with R1= 1 kn, R2= 2 kn, R3= 4 kQ and R4= 8 kQ.arrow_forward

The mean is simply the average of the numbers. The standard deviation is a statistic that tells you how tightly all the various data are clustered around the mean in a set of data. For example, what is the average age of the students in a class? How close are the ages? If all the students are the same age, the deviation is 0.

- Summary: Given integer values for red, green, and blue, subtract the gray from each value. Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray). Given values for red, green, and blue, remove the gray part. Ex: If the input is: 130 50 130 the output is: 80 0 80 Find the smallest value, and then subtract it from all three values, thus removing the gray.

Assume a small airplane with seat numbering as follows: 1 A B C D 2 A B C D 3 A B C D 4 A B C D 5 A B C D 6 A B C D 7 A B C D The program should display the seat pattern, with an 'X' marking the seats already assigned. For example, after seats 1A, 2B, and 4C are taken, the display should look like this: 1 X B C D 2 A X C D 3 A B C D 4 A B X D 5 A B C D 6 A B C D 7 A B C D After displaying the seats available, the program prompts for the seat desired, the user types in a seat, and then the display of available seats is updated. This continues until all seats are filled or until the user signals that the program should end. If the user types in a seat that is already assigned, the program should say that that seat is occupied and ask…arrow_forwardWrite a program using C languagearrow_forward
