(1 point) Assume that A is a matrix with four rows. Find the elementary matrix E such that E A gives the matrix resulting from A after the given row operation is performed. Then find $E^{-1}$ and give the elementary row operation corresponding to $E^{-1}$. $6R_3 \rightarrow R_3$ E = $E^{-1}$ = The elementary row operation corresponding to $E^{-1}$ is: A. $\frac{1}{6}R_3 \rightarrow R_3$ B. $R_3 \rightarrow \frac{1}{6}R_3$ C. $6R_3 \rightarrow R_3$ D. $\frac{6}{1}R_3 \rightarrow R_3$ E. $\frac{1}{6}R_3 + R_3 \rightarrow R_3$

2. To represent a signal in frequency we need to use the Fourier transform. a. Derive in full the Fourier transform of the signal $M(f) = F\{m(t)\}$ and draw the result by hand. b. In Matlab, we are representing the signal in time using vectors with discrete values. Therefore, we need to apply a discrete version of the Fourier transform. i. Use the following command to generate a discrete Fourier transform of the signal $m$ for $\Delta t = 0.01$ sec and $N = 256$: $M = abs(fftshift(fft(m, N) * \Delta t));$ Now, generate a frequency vector: $f = [-\frac{N}{2}:\frac{N}{2} - 1]/(N * \Delta t)$ ii. Generate a figure presenting $M$ as a function of $f$, for range $-5 \leq f \leq 5$ Hz iii. Compare the curve in the figure to your hand drawn spectrum and provide an account for all discrepancies you observe. c. Read Matlab's documentation on the fft and fftshift functions at

Many people believe that once a person finishes school and is an adult, that cognitive and socioemotional development stops. That is simply not the case. People continue to develop in a variety of ways throughout their lifetime. Let's discuss adulthood cognitive and socioemotional development. Include Fluid and Crystallized Intelligence... What are they and what happens throughout adulthood with these forms of cognitive thinking? What happens with the other types of intelligence and thinking/reasoning/comprehension/memory as we progress through adulthood? What are the other factors to consider that may be playing a role with development in adulthood (staying active in a career, staying physically active, active with spiritual life/community, midlife crisis, stress levels, being involved in leisure activities/hobbies, having a good support system, etc.)? Discuss in at least 3 paragraphs. Writing Format for Responding to the Prompt Address each of the items below in three-four paragraphs total. Using APA formatting, please cite all resources used (textbooks and other sources) within the text of your response and include a reference list at the end of the assignment. 1. Give a brief overview of adulthood cognitive and socioemotional development. 2. Define and discuss fluid and crystallized intelligence. 3. What happens to other cognitive processes as individuals progress through adulthood? 4. What other factors might play a role in development in adulthood? 5. Reference list.
