answer:Dialogue in writing is the conversation between two or more characters. It is used to reveal character, advance the plot, and create conflict. Dialogue should be natural and believable, and it should reflect the characters' personalities and backgrounds.

answer:Given x=(-14-8 i) log (2) and y=(10+9 i) log (2), we can simplify each expression as follows: x=(-14-8 i) log (2) = -14 log (2) - 8 i log (2) y=(10+9 i) log (2) = 10 log (2) + 9 i log (2) Now, we can divide x by y to get: frac{x}{y} = frac{-14 log (2) - 8 i log (2)}{10 log (2) + 9 i log (2)} To simplify this expression, we can multiply both the numerator and denominator by the complex conjugate of the denominator: frac{x}{y} = frac{(-14 log (2) - 8 i log (2))(10 log (2) - 9 i log (2))}{(10 log (2) + 9 i log (2))(10 log (2) - 9 i log (2))} Expanding and simplifying the numerator and denominator, we get: frac{x}{y} = frac{-140 log^2 (2) + 126 i log^2 (2) + 72 log^2 (2) - 72 i log^2 (2)}{100 log^2 (2) + 81 log^2 (2)} Combining like terms, we get: frac{x}{y} = frac{-68 log^2 (2) + 54 i log^2 (2)}{181 log^2 (2)} Factoring out log^2 (2) from both the numerator and denominator, we get: frac{x}{y} = frac{-68 + 54 i}{181} Finally, we can simplify this expression by dividing both the numerator and denominator by their greatest common factor, which is 181: frac{x}{y} = -frac{212}{181}+frac{46 i}{181} The answer is -frac{212}{181}+frac{46 i}{181}

answer:The modulus (norm) of the complex number re^{itheta}, where r is the distance from the origin in the complex plane and theta is the argument, is equal to r. In this case, r = 7. Hence, the norm is 7. The argument (phase angle) is given by theta, which in the exponential form e^{itheta} is already provided. Thus, the argument is frac{173 pi }{180} radians.
