Suppose $x(t)$ is a periodic signal with fundamental frequency 2 rad/s. The Fourier coefficients of $x(t)$ are given by $c_0 = \frac{1}{2}$, $c_1 = c_{-1} = 1$, $c_3 = c_{-3} = 2$ and $c_k = 0$ for other $k \in \mathbb{Z}$. Also suppose $\tilde{x}(t)$ is a periodic signal with fundamental frequency 3 rad/s. The Fourier coefficients of $\tilde{x}(t)$ are given by $\tilde{c}_0 = -1$, $\tilde{c}_1 = \tilde{c}_{-1} = 2$, $\tilde{c}_2 = \tilde{c}_{-2} = 3$ and $\tilde{c}_k = 0$ for other $k \in \mathbb{Z}$. Now consider the signal, $x(t) = 2x(t) - \tilde{x}(t)$. Find the fundamental period and Fourier coefficients $c_k$ for $x(t)$. Note, you need to use properties of Fourier series covered in Lecture 19.

15 points Exercise 2.17 (Algo) Assessing Financial Results (LO2-5) The Walt Disney Company's annual report for the year ended October 3, 2015, includes income statements for the years ending in 2013, 2014, and 2015. Net income for these three years is as follows (all in millions): $4,953 (2013), $5,988 (2014), and $6,556 (2015). Further analysis of the same income statements reveals that revenues were the following amounts for these same years (all in millions): $45,027 (2013), $46,059 (2014), and $47,164 (2015). State each year's net income as a percentage of revenues. (Round your answers to 2 decimal places (i.e 1234 should be entered as 12.34).) elook Print References Year Net Income 2013 % 2014 % 2015 %
