x(n) = 3.45 Sin($\frac{4\pi}{8}$n). (3 points). 3. Determine whether or not the LTI systems with the following impulse responses are causal and stable. Note that simply writing causal / noncausal, or stable / unstable is not enough, the verification of your answers are required to gain points from this question. (15 puan). a. h(n) = (-0.5)^n u(n) + (1.01)^n u(n - 1) b. h(n) = (-0.5)^n u(-n-1) + (1.01)^n u(1 - n) c. h(t) = e^{-2t}u(-1-t). Determine whether or not the sust time-inun

Express the solution of the given initial value problem as a sum of two oscillations. Primes denote derivatives with respect to time t. Graph the solution function x(t) in such a way that you can identify and label its period. $$x'' + 49x = 26 \cos 6t; x(0) = x'(0) = 0$$ $$x(t) = $$ (Simplify your answer. Type an exact answer, using radicals as needed.) Graph the solution function x(t). Choose the correct graph below. Identify the period. $$P=$$ (Tune an exact answer in terms of $$\pi$$.)
