Chapter 4, Problem 14E
Suppose that you work for a beverage company. The company wants to know the optimal cost for a cylindrical container that holds a specified volume. Write a fragment of code that uses an ask-before-iterating loop. During each iteration of the loop, your code will ask the user to enter the volume and the radius of the cylinder. Compute and display the height and cost of the container. Use the following formulas, where V is the volume, r is the radius, h is the height, and C is the cost.

A nutritionist who works for a fitness club helps members by evaluating their diets. As part of her evaluation, she asks members for the number of fat grams and carbohydrate grams that they consume in a day. Then, she calculates the number of calories that result from the fat using the following formula: Calories from fat = Fat grams × 9Next, she calculates the number of calories that result from the carbohydrates using the following formula: Calories from carbs = Carbs grams × 4Create an application that will make these calculations. In the application, you should have the following methods:• FatCalories–This method should accept a number of fat grams as an argument and return the number of calories from that amount of fat.• CarbCalories–This method should accept a number of carbohydrate grams as an argument and return the number of calories from that amount of carbohydrates.
In Python
A soup company is interested in finding out how much of their soup will go into various sized cans. The user will input the diameter of the can end, and the height of the can. The volume of a cylinder is the well known formula: volume = area of the ends * height of cylinder. The twist is that a can of soup can not be completely filled to the top; only 95% of the volume can be filled with soup; the remaining 5% must remain empty to allow for expansion. NOTE: when computing the area, use pi to at least 5 significant digits (eg, 3.14159) or use the constant math.pi.
You should define a function named soup_volume which takes two parameters, the diameter of the can in cm, and the height of the can in cm, in that order. The function should return a float value, which is the volume of soup that the can is able to hold. The function should not round the value, but when printing the value in the main program, format it to show only 2 decimal places.

The concentration (C) of insulin in the body is described by the following equation
C = C0e^-40t / M
Where
C0 = 85 pmol/L is the initial insulin concentration, t is time in minutes, M is the person
mass in kg.
a) Write code that will calculate the insulin concentration of two people with weighs 60
Kg and 100 Kg. Simulate the insulin concentration for 4 minutes in steps of 0.1
minute.
b) Plot the insulin concentration of the two people on the same graph. For the first
curve plot a magenta solid line, square marker, cyan for MarkerFaceColor, and
MarkerSize of 6. For the second curve plot a black dashed line with LineWidth of 2.
c) Your plot should have a title, a legend, and appropriate labels for the x and y axis.

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 company wants to know the optimal cost for a cylindrical container that holds a specified volume. Write a program that asks the user to enter the volume and radius of the cylinder. Compute and display the height and cost of the cylindrical container. Use the following formulas, where V is the volume, R is the radius, H is the height, and C is the cost of the cylindrical container. H =V / (PI * R) C = 2*PI*R*(R + H) Note: PI=3.14159arrow_forwardIn python, a) In the Hi-Lo game, the player begins with a score of 1000. The player is prompted for the number of points to risk and a second prompt asks the player to choose either High or Low. The player’s choice of either High or Low is compared to a random number between 1 and 13, inclusive. If the number is between 1 and 6 inclusive, then it is considered “low”. A number between 8 and 13 inclusive is “high”. The number 7 is neither high nor low, and the player loses the points at risk. If the player had guessed correctly, the points at risk are doubled and added to the total points. For a wrong choice, the player loses the points at risk. Create a HiLo application based on this specification. Application output should look similar to b) Modify the application to allow the player to continue until there are 0 points left. At the end of the game, display the number of guesses the user took before running out of points.arrow_forward
