- can you help me with 1 to 3R studio : profit margin for each month - equals to profit a after tax divided by revenue profit.margin <- round(profit_after_tax/revenue, 2)*100 profit.margin Result: 12 18 -30 -22 -5 63 50 28 23 -11 4 53 How to change the results based on the note: All results need to be presented as vectors. Results for dollar values need to be calculated with $0.01 precision, but need to be presented in Units of $1,000 (i.e. 1k) with no decimal points. Results for the profit margin ratio need to be presented in units of % with no decimal points. Note: You colleague has warned you that it is okay for tax for any given month to be negative (in accounting terms, negative tax translates into a deferred tax asset).For the following code: for ( a = 1, b = 5, c = 3; a < 4; a++, b++ ) { c = a * b + c; } Indicate what values for the following variable will be when the code endsa=b=c=
- Colab the code in formto.Consider the following sequence of equations involving Fibonacci numbers: 1 + 2 = 3 1 + 2 + 5 = 8 1 + 2 + 5 + 13 = 21 1 + 2 + 5 + 13 + 34 = 55 ⋮ Find the subscript that will make the following equation true. F1 + F3 + F5 + ⋯ + F21 = F21The quadratic formula is used to solve a very specific type of equation, called aquadratic equation. These equations are usually written in the following form:ax2 + bx + c = 0The Quadratic Formula x = ( -b ± √( b^2 - 4ac ) ) / ( 2a ) Where a, b, and c are constants with a ≠ 0. (If a = 0, the equation is a linear equation.)The discriminant is the part of the formula in the square root. If the value of the discriminant is zero then the equation has a single real root. If the value of thediscriminant is positive then the equation has two real roots. If the value of thediscriminant is negative, then the equation has two complex roots.Write a program that finds the roots of the quadratic equation using the Quadratic Formula. Write a function named discriminant in the file, Disc.py, to calculate and return the discriminant of the formula. Let the main function call the discriminant function and then calculate the solution(s) of the equation. Do not calculate the solutions in the discriminant…
- Suppose you want to deposit a certain amount of money into a savings account, and thenleave it alone to draw interest for the next 10 years. At the end of 10 years, you would like tohave $10,000 in the account. How much do you need to deposit today to make that happen?You can use the following formula, which is known as the present value formula, to find out:The terms in the formula are as follows: [5 marks]• P is the present value, or the amount that you need to deposit today.• F is the future value that you want in the account. (In this case, F is $10,000.)• r is the annual interest rate.• n is the number of years that you plan to let the money sit in the account.Write a method named presentValue that performs this calculation. The method should accept the future value, annual interest rate, and number of years asarguments. It should return the present value, which is the amount that you need to deposit today.Demonstrate the method in a program that lets the user experiment with…Q1: One way to generate the value of Eulers number e is given by the formula e = lim (1 + n00 Complete the code that calculates the expression inside the limit, that is, (1 + )", for some value n.
