7. Write a function that evaluates the area of a pentagon. Use "math.pi", for pi, and "math.sqrt" for square root. Write the solution on the space provided below. You do not need to run the code. 311 3.2 (Geometry: area of a pentagon) Write a program that prompts the user to enter the length from the center of a pentagon to a vertex and computes the area of the pen- tagon, as shown in the following figure. The formula for computing the area of a pentagon is Area 3√3 2 -s², where s is TT the length of a side. The side can be computed using the formula s = 2r sin 5' where r is the length from the center of a pentagon to a vertex. Here is a sample run: Enter the length from the center to a vertex: 5.5 Enter The area of the pentagon is 108.61

2.19 LAB*: Program: Food receipt   Note: When accuracy is essential, floats are not used to represent currency due to rounding and accumulation errors. Python provides several primitives specifically developed to implement financial applications. However, these topics are beyond the scope of this lab. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print(f'{your_value:.2f}')

01. а) Using colon notation write code in MATLAB to store the below matrix to a variable – matrix1 [5.0 6.2 3.1 9.6 7.4 17.1 l17 6.1 -5.2] b) A sequence of numbers is given by the equation; Xn+2 = Xn+1 + Xn, je if x1 and x2 = 1 then x3= 1+1 =2. Create code in MATLAB that will calculate the first 12 terms of this sequence, with the values x1 and x2 being the last 2 digits of your student number (if it is 0 assume it is 1 instead). c) Using the sequence in the above question, use nested for loops to create the below matrix to a variable – matrix2. X4 X5 X6 [X9 X7 X8 X10 X11.
