Homework write a program that will add the terms of an infinite geometric series. The program should read the first term (a) and the common ratio (r) for the series. It should the compute the sum in two ways: by formula (s=a/1-r), and by adding the individual terms until the answer agrees with the formula to 7 significant digits. The print the formula answer, the answer found by adding terms, and the number of terms that were added. Print the sums to at least ten places. Verify input with a while loop. Two real values are equal to n significant digits if the following condition is true: |a-b|<|a*10^-n| Wrong test - this won't work if r is very near one. Try a=2, r=.99999 With smaller values of r, it is asking for too much precision. With a=2,r=.99, it is getting 10 significant digits. HELP ME FIX CODE.

Arranging Pebbles Write a program that can arrange a group of pebbles into its designated position. We have 4 types of pebbles: Red, white, blue, and green colored pebbles. Supposed that we have an n-number of pebbles, the program should be able to check the color of the pebble and arrange them in such a way that it will look something like this: Example, if there are 9 pebbles; 1 green, 3 white, 2 blue, and 3 red, the program will output something like this: RRRWWWBBG NOTE: The program will let the user to enter the pebbles and then the program will automatically arrange it. Sample output 1: R=Red, W-White, B=Blue, G=Green Enter pebbles: rwgbrgwbrg Arranged pebbles: RRRWWBBGGG Sample output 2: R=Red, W-White, B=Blue, G=Green Enter pebbles: abcde Invalid input Notice that the arrangement of the pebbles is: Red, White, Blue, Green

Transient PopulationPopulations are affected by the birth and death rate, as well as the number of people who move in and out each year. The birth rate is the percentage increase of the population due to births and the death rate is the percentage decrease of the population due to deaths. Write a program that displays the size of a population for any number of years. The program should ask for the following data: The starting size of a population P The annual birth rate (as a percentage of the population expressed as a fraction in decimal form)B The annual death rate (as a percentage of the population expressed as a fraction in decimal form)D The average annual number of people who have arrived A The average annual number of people who have moved away M The number of years to display nYears Write a function that calculates the size of the population after a year. To calculate the new population after one year, this function should use the formulaN = P + BP - DP + A - Mwhere N is the…
