- If the annual household income is between $30,000 and $40,000 and the household has at least three children, the amount is $1,000 per child.
- If the annual household income is between $20,000 and $30,000 and the household has at least two children, the amount is $1,500 per child.
- If the annual household income is less than $20,000, the amount is $2,000 per child.
Implement a method for this computation. Write a program that asks for the household income and number of children for each applicant, printing the amount returned by your method. Use −1 as a sentinel value for the input.

Context: Measuring Air Quality
Levels of various air borne pollutants such as Nitrogen Monoxide (NO), Nitrogen Dioxide (NO2) and particulate matter (also called particle pollution) are all major contributors to the measure of overall air quality.
For instance, NO2 is measured using micrograms in each cubic metre of air (㎍/m3). A microgram (㎍) is one millionth of a gram. A concentration of 1 ㎍/m3 means that one cubic metre of air contains one microgram of pollutant.
To protect our health, the UK Government sets two air quality objectives for NO2 in their Air Quality Strategy
The hourly objective, which is the concentration of NO2 in the air, averaged over a period of one hour.
The annual objective, which is the concentration of NO2 in the air, averaged over a period of a year.
The following table shows the colour encoding and the levels for Objective 1 above, the mean hourly ratio, adopted in the UK.

The United States federal personal income tax is calculated based on filing status
and taxable income. There are four filing statuses: single filers, married filing jointly,
married filing separately, and head of household. The tax rates vary every year. Table
4.2 shows the rates for 2009. If you are, say, single with a taxable income of $10,000,
the first $8,350 is taxed at 10% and the other $1,650 is taxed at 15%. So, your tax is
$1,082.50.

Section: FactThyroid function is measured using a factor called TSH, which stands for thyroid-stimulatinghormone. A TSH test is a blood test that measures this hormone. TSH normal values are 0.5 to 5.0mIU/L. If TSH is over 5.0 thyroid is underactive. On the other hand, if TSH is less than 0.5 thyroid isoveractive.

- When you borrow money to buy a house, a car, or for some other purpose, you repay the loan by making periodic payments over a certain period of time. Of course, the lending company will charge interest on the loan. Every periodic payment consists of the interest on the loan and the payment toward the principal amount. To be specific, suppose that you borrow $1,000 at an interest rate of 7.2% per year and the payments are monthly. Suppose that your monthly payment is $25. Now, the interest is 7.2% per year and the payments are monthly, so the interest rate per month is 7.2/12 = 0.6%. The first months interest on $1,000 is 1000 0.006 = 6. Because the payment is $25 and the interest for the first month is $6, the payment toward the principal amount is 25 6 = 19. This means after making the first payment, the loan amount is 1,000 19 = 981. For the second payment, the interest is calculated on $981. So the interest for the second month is 981 0.006 = 5.886, that is, approximately $5.89. This implies that the payment toward the principal is 25 5.89 = 19.11 and the remaining balance after the second payment is 981 19.11 = 961.89. This process is repeated until the loan is paid. Write a program that accepts as input the loan amount, the interest rate per year, and the monthly payment. (Enter the interest rate as a percentage. For example, if the interest rate is 7.2% per year, then enter 7.2.) The program then outputs the number of months it would take to repay the loan. (Note that if the monthly payment is less than the first months interest, then after each payment, the loan amount will increase. In this case, the program must warn the borrower that the monthly payment is too low, and with this monthly payment, the loan amount could not be repaid.)arrow_forwardLoan negotiation is usually not a straightforward task. A type of loan is the discount installment loan. This type of loan has the following characteristics. Supposing a loan has face value of GHC 1000, interest is 13% and the duration is 24 months. The interest is compounded by multiplying the face value by 0.13 to produce GHC 130. The figure (130) is then multiplied by the loan period of 2 years to give GHC 260 as the total interest owed. This amount is immediately deducted from the face value leaving the customer with only GHC 740. Repayment is then made in monthly equal installments based on the face value. This means that the monthly payment will be GHC 1000 divided by 24 which is approximately 41.67. This method of calculating the monthly repayment is not too bad if the consumer needs only GHC 760 but the calculation is a bit complicated if the consumer needs GHC 1000. a.

One question you might want to ask is: what is the amount of power my wind turbine can produce? To answer this question, you will need at least the following information: The average wind speed (in m/s) The operating efficiency of your wind turbine (in %) The radius of the blades on your wind turbine (in meters) To compute the maximum power output for your wind turbine, you would need the following math formulas: A= πr2, which represents the cross-sectional area of a circle (π = 3.14159265). Pmax = 0.5ρAv3, which calculates the maximum available power given the wind speed in m/s (ν), cross-sectional area of the blades in m2 (A), and the density of the air (ρ = 1.2 kg/m3). Once you have the maximum available power, computing the actual amount of power (not the maximum) produced by the wind turbine is a matter of determining the amount of power based on the operating efficiency.

This type of loan has the following characteristics. Supposing a loan has face value of GHC 1000, interest is 10% and the duration is 24 months.

This amount is immediately deducted from the face value leaving the customer with only GHC 760. Repayment is then made in monthly equal installments based on the face value.

BMI does not measure body fatdirectly, but research has shown that BMI correlates to direct measures of body fat, such as underwater weighing and dual-energy X-ray absorptiometry. The formula for BMI is Weight/Height2 Where weight is in kilograms and height is in meters. Write a program that prompts for metric weight and height and outputs the BMI. For example, an execution could look like this:Please enter weight in kilograms: 50Please enter height in meters: 1.58BMI is: 20.0288415318arrow_forward• A circuit consists of a 12 V battery connected across a single resistor.

- Summary During winter when it is very cold, typically, everyone would like to know the windchill factor, especially, before going out. Meteorologists use the following formula to compute the windchill factor, W: W = 35.74 + 0.6215 × T - 35.75 × V0.16 + 0.4275 × T × V0.16 where V is the wind speed in miles per hour and T is the temperature in degrees Fahrenheit. Instructions Write a program that prompts the user to input the wind speed in miles per hour, and the temperature in degrees Fahrenheit. The program then outputs the current temperature and the windchill factor. Your program must contain at least two functions: one to get the user input and the other to determine the windchill factor.arrow_forwardLoan negotiation is usually not a straightforward task.

The formula is: Mitotic index= # of cells in mitosis / # of cells in total x 100% Use this formula to calculate the mitotic index for the diagram seen in Question 5. Show your calculations (you can use * for multiplication and / for division if you prefer) and indicate your final answer as a percentage rounded to the nearest tenth of a percentage (1 decimal place).
