1. The Heat Index HI, calculated from the air temperature and relative humidity, is the apparent temperature felt by the body. An equation used by the National Weather Service for calculating the HI is given by: HI = -42.379 + 2.049015237 + 10.14333127R - 0.22475541R – 6.83783 * 10-37T² - 5.481717 * 10-²R² + 1.22874 * 10-3T² + 8.5282 + 10-4TR² – 1.99 * 10-6T?R? where Tis the temperature in degrees F and R is the relative humidity in integer percentage. Write a MATLAB program in a script file that calculates HI . For input the program asks the user to enter values for T and R. For output the program displays the message: "The Heat Index temperature is: XX," where XX is the value of the heat index rounded to the nearest integer. Execute the program entering T = 90°F and R = 90 %.

Homework: Solve the following problems by first writing a program in a script file and then executing the program. 1. The Heat Index HI, calculated from the air temperature and relative humidity, is the apparent temperature felt by the body. An equation used by the National Weather Service for calculating the HI is given by: HI = -42.379 + 2.049015237 + 10.14333127R – 0.22475541R – 6.83783 * 10-3T2 - 5.481717 * 10-2R² + 1.22874 * 10-3T2 + 8.5282 * 10-4TR2 – 1.99 * 10-6T2R2 where Tis the temperature in degrees Fand R is the relative humidity in integer percentage. Write a MATLAB program in a script file that calculates HI. For input the program asks the user to enter values for T and R. For output the program displays the message: "The Heat Index temperature is: XX," where XX is the value of the heat index rounded to the nearest integer. Execute the program entering T = 90°F and R = 90 %. 2. The monthly saving P that has to be deposit in a saving account that pays an annual interest rate of r in order to save a total amount of F in N years can be calculated by the formula: F("/12) P = - (1+"/12)* 12N - 1 Calculate the monthly saving that has to be deposit in order to save $100,000 in 5, 6, 7, 8, 9, and 10 years if the annual interest rate 4.35%. Display the results in a two-column table where the first column is the number of years and the second column is the monthly deposit. 3. The growth of some bacteria populations can be described by N = N,ekt where N is the number of individuals at time t, No is the number at time t = 0, and k is a constant. Assuming the number of bacteria doubles every 40 minutes, determine the number of bacteria every two hours for 24 hours starting from an initial single bacterium.
