According to the American Heart Association, as you exercise you should periodically check your heart rate to ensure you are in your target zone. Your target zone is a range that is 50% to 85% of your maximum heart rate. The formula for calculating a persons maximum heart rate is 220 minus your age in years.
Write a program that reads the users current heart rate, birthday, and the current day (each consisting of month, day, and year). The program should calculate the persons age (in years), the person's maximum heart rate, and the person's target heart rate zone range.
Output the users age, current heart rate, target zone range. If their heart rate is in the target zone congratulate them, if it is out of their target zone warn them.
Required Methods (Write these first and use them in your algorithm): (your code, particularly for computeAge, must be 100% clear and documented - it's the core of this assignment!)
int computeAge(int birthMonth, int birthDay,…

A complex number is a number in the form a+bi, where a and b are real numbers and i is √(-1)
The numbers a and b are known as the real part and imaginary part of the complex number, respectively. You can perform addition, subtraction, multiplication, and division for complex numbers using the following formulas:
a + bi + c + di = (a+c) + (b+d)i (addition)
a + bi − (c + di) = (a−c) + (b−d)i (subtraction)
(a + bi) * (c + di) = (ac−bd) + (bc+ad)i (multiplication)
(a + bi) / (c + di) = (ac+bd) / (c2+d2) + (bc−ad)i / (c2+d2) (division)
You can obtain the Absolute Value for a complex number using the following formula:
|a + bi| = √(a2 + b2)
A Complex number can be interpreted as a point on a plane by identifying the (a,b) values as the coordinates of the point. The absolute value of the complex number corresponds to the distance of the point to the origin, as shown in the example below.

Summary
In this lab, you complete a prewritten Java program for a carpenter who creates personalized house signs. The program is supposed to compute the price of any sign a customer orders, based on the following facts:
The charge for all signs is a minimum of $35.00.
The first five letters or numbers are included in the minimum charge; there is a $4 charge for each additional character.
If the sign is made of oak, add $20.00. No charge is added for pine.
Black or white characters are included in the minimum charge; there is an additional $15 charge for gold-leaf lettering.
Instructions
1. Ensure the file named HouseSign.java is open.
2. You need to declare variables for the following, and initialize them where specified:
A variable for the cost of the sign initialized to 0.00 (charge).
A variable for the number of characters initialized to 8 (numChars).
A variable for the color of the characters initialized to "gold" (color).
A variable for the…

Each score's name is based on the actual strokes taken compared to par: "Eagle": number of strokes is two less than par "Birdie": number of strokes is one less than par "Par": number of strokes equals par "Bogey": number of strokes is one more than par Given main() and two input integers that represent par and the number of strokes used, write a method, golfScore(), that returns the appropriate score name (a String). Return "Error" if par is not 3, 4, or 5.

As it is a new chef's creation, you want to understand the ability to make Cube Cakes look exactly the same. For this, you need to write a plan that will calculate the similarities between the two Cube cakes provided. Each piece of cake can be displayed as an N-size cube where each cube cell contains lower case letters ('a' - 'z'). The similarity between the two Cube Cakes (each N size) is defined as the standard sub-cube of the same size found in the same area in both Cube Cakes. Two sub-cubes are considered normal if at least P% of the corresponding characters are equal. You need to find the S size of the largest sub-cube and the number of common sub-cubes of…arrow_forward5.
