Starting with an initial value of $P(0)=55,$ the population of a prairie dog community grows at a rate of $P^{\prime}(t)=20-t / 5$ (in units of prairie dogs/month), for $0 \leq t \leq 200.$
a. What is the population 6 months later?
b. Find the population $P(t),$ for $0 \leq t \leq 200.$

(The Account class) Design a class named Account that contains:
? A private int data field named id for the account.
? A private float data field named balance for the account.
? A private float data field named annualInterestRate that stores the current
interest rate.
? A constructor that creates an account with the specified id (default 0), initial
balance (default 100), and annual interest rate (default 0).
? The accessor and mutator methods for id, balance, and annualInterestRate.
? A method named getMonthlyInterestRate() that returns the monthly
interest rate.
? A method named getMonthlyInterest() that returns the monthly interest.
? A method named withdraw that withdraws a specified amount from the
account.
? A method named deposit that deposits a specified amount to the account.
Draw the UML diagram for the class, and then implement the class. (Hint: The method getMonth7yInterest() is to return the monthly interest amount, not the interest rate. Use this formula to calculate the monthly interest: batance month7yInterestRate. month7yInterestRate is annualInterestRate / $12 .$ Note that annual InterestRate is a percent (like $4.5 \%$ ). You need to divide it by $100 .$
Write a test program that creates an Account object with an account id of $1122,$ a balance of $\$ 20,000,$ and an annual interest rate of $4.5 \%$. Use the withdraw method to withdraw $\$ 2,500$, use the deposit method to deposit $\$ 3,000$, and print the id, balance, monthly interest rate, and monthly interest.

INSTANT ANSWER

Verify the correctness of the Selection Sort algorithm (ascending order) using induction. Hint: consider two cases to prove the inductive step:1) The best-case scenario, where the n+1st element of an array is the largest one;2) The worst-case scenario, where the n+1st element of an array is the smallest one and must be moved to the 1st position.
