A ham is taken out of a 150 degrees F oven, and placed in a room that is 72 degrees F. The amount of time it takes for the ham to cool to a temperature of x degrees F is given by the equation $f(x) = 100 \cdot ln(\frac{78}{x - 72})$. Use the graph of the function to determine the temperature of the ham after 15 minutes. Write the equation that needs to be solved to answer this question. Convert this equation to exponential form, and solve for the answer algebraically.

I have confirmed that the plaintext is a phrase of words, not random characters. 1.30 We describe another stream cipher, which incorporates one of the ideas from the Enigma system used by Germany in World War II. Suppose that Π is a fixed permutation of Z26. The key is an element K ∈ Z26. For all integers i > 1, the keystream element zi ∈ Z26 is defined according to the rule zi = (K + i - 1) mod 26. Encryption and decryption are performed using the permutations Π and Τ1, respectively, as follows: ex = (x + z) mod 26 and dy = (-1y - z) mod 26, where z ∈ Z26. Suppose that Π is the following permutation of Z26: 0 6 8 9 10 16 22 23 24 25 13 14 15 16 21 22 23 4 10 6 24 25 18 12 20 The following ciphertext has been encrypted using this stream cipher; use exhaustive key search to decrypt it: WRTCNRLDSAFARWKXFTXCZRNHNYPDTZUUKMPLUSOXNEUDOKLXRMCBKGRCCURR

3.24 The message signal $m(t) = 10 \text{ sinc}(400t)$ frequency modulates the carrier $c(t) = 100 \cos 2\pi f_c t$. The modulation index is 6. 1. Write an expression for the modulated signal $u(t)$? 2. What is the maximum frequency deviation of the modulated signal? 3. What is the power content of the modulated signal? 4. Find the bandwidth of the modulated signal. 2. Consider Problem 3.24 in your textbook. Provide the solution if the message signal is $m(t) = 10 \text{ sinc}(500t)$, and the modulation index is 7. (10 points).
