equity/debt an IOU or promise to pay from/a claim to partial ownership in Clinton and the othwr stockholders/the bondholders Suppose Clinton decides to use $3,500 currently held as savings to make a financial investment. One method of making a financial investment is the purchase of stock or bonds from a private company. Suppose Bayzer, a pharmaceutical firm, is selling stocks to raise money for a hew lab. This practice is called finance. Huying a share of Bayzer stock would give Clinton the firm. In the event that Bayzer runs into financial difficulty, will be paid first. Suppose Cinton chooses to bury 250 shares of Bayzer stock. Which of the following statements are correct? Check anl that apply. Expectations of a recession that Will reduce economywide corporate pronts will likely cause the value of Clinton's shares to decline. The Dow Jones Industrial Average is an example of a stock exchange where he can purchase Bayzer stock. An increase in the percelved profitability of Bayzer will likely cause the value of clinton's shares to rise. Alternotively, Clinton could undertake theic financiaf investment by purchasing bonds issued by the U.S. government. Assuming that everything else is equal, a corporate bond issued by an electronics manufacturer most likely pays a municipal bond issued by a state..

Enterprises recently paid a dividend, D0, of $3.50. It expects to have nonconstant growth of 12% for 2 years followed by a constant rate of 10% eafter. The firm's required return is 11%. a. How far away is the horizon date? I. The terminal, or horizon, date is Year 0 since the value of a common stock is the present value of all future expected dividends at time zero. II. The terminal, or horizon, date is the date when the growth rate becomes nonconstant. This occurs at time zero. III. The terminal, or horizon, date is the date when the growth rate becomes constant. This occurs at the beginning of Year 2 . IV. The terminal, or horizon, date is the date when the growth rate becomes constant. This occurs at the end of Year 2. V. The terminal, or horizon, date is infinity since common stocks do not have a maturity date..

Encryption is a process of converting a message, image, or any other form of data into encoded data that can only be decoded by someone who can decrypt the message (usually with a key or the like). The science of writing secret codes is called cryptography For thousands of years, cryptography has made secret messages that only the sender and recipient could read, even if someone captured the messenger and read the coded message. A secret code system is called a cipher. A good encryption algorithm should produce output that looks random to a bystander but is easily decipherable with the correct key. Thus, encryption algorithms make use of pseudo- random encryption keys. Let's start with some definitions: - Encryption or Enciphering: the process of encoding messages to make them unreadable. This algorithm has two inputs: a plaintext and a secret key. - Decryption or deciphering: making encrypted messages readable again by decoding them (recovering the plaintext from ciphertext). - Cipher: an algorithm for performing encryption and decryption. - Plaintext: the original message. - Ciphertext: the encrypted message. Note: a ciphertext still contains all of the original message information, even if it looks nonsense. - Secret key; the same key used for encryption and decryption. - Cryptography, the science of studying ciphers. For this project, you need to develop a game that converts normal English words into secret codes. In order to convert, the program randomly applies an encryption algorithm to any given message. The algorithms you need to implement include Substitution, Playfais Caesas Transposition, Product, and RSA ciphers. 1. Substitution cipher, replacing each letter of the alphabet in the plaintext with a different letter in the ciphertext. For example, if you want to encrypt the word 'Cat', you need to come up with a substitution for each plaintext letter to a ciphertext letter. For example, you may substitute the letter ' a ' with the letter ' o '. The rule is that the letter we substitute can only be used once. So, the letter 'o' is crossed off as it has already been used. The same would be applied to all alphabetic letters. 1. Substitution cipher; replacing each letter of the alphabet in the plaintext with a different letter in the ciphertext.

It employs a table where one letter of the alphabet is omitted, and the letters are arranged in a 55 grid. For more informat.
