A Motzkin path of length n is a sequence of points (0, 0) = P0, P1, ..., Pn = (n, 0) where Pi - Pi-1 ∈ {(1, 1), (1, -1), (1, 0)} and the y-coordinate of Pi is nonnegative for all i. Below are all the Motzkin paths from (0, 0) to (4, 0). (a) Find a recursive construction for the set of all Motzkin paths. (b) Use the construction you found in the previous part to find the generating function for Motzkin paths of any length.

5. Numbers as Strings Complete the describing function in the editor. When given a integer n, returns: • the string representation of the integer but only for integers in the (inclusive) range 0-10 • for integers outside the range, it return OTHER Example • For n = 2, the output should be describing(n) "TWO" • For n = 3, the output should be describing(n) "THREE" • For n = -11, the output should be describing(n) = "OTHER" Function Description describing has the following parameter: int n: the integer to analyze Returns: String: an uppercase string containing the description of the integer Language C++ 1 #include <bits/stdc++.h> Autocomplete Ready /* Complete the 'describing' function below. The function is expected to return a STRING. The function accepts INTEGER n as parameter. */ string describing(int n) { } int main()

Question 4. (25 Points) 200L/s of water is flowing in a pipe having a diameter of 300mm. If the pipe is bent by 130°, find the magnitude and direction of the resultant force on the bend. Neglect the elevation difference between the ends. The absolute pressure of water flowing is 39N/cm². Atmospheric pressure can be used as 100kPa. The mass of the elbow and the water inside is 7kg.

sampling interval is T = 0.3 s. 1) A plant is regulated using a digital control system as shown in Figure 1 where the R(z) Y(z) E(z) K(z) U(z) G_a(z) Controller D/A converter + Plant Figure 1: Digital control system for an oscillator (a) The s-domain transfer functions of the D/A converter and the plant are respectively given by $G_{DAC}(s) = \frac{1 - e^{-sT}}{s}$ and $G(s) = \frac{1}{s^2 + P^2}$ Based on T = 0.3 s, find $G_d(z)$ the z-domain transfer function between U(z) and Y(z). P has the value determined on the cover page. [Hints: $G_d(z)$ has an equivalent s-domain transfer function of $G_{DAC}(s) \times G(s)$.

Solve the following differential equation using Laplace transforms manually and solve it using the MATLAB symbolic toolbox. Moreover, determine if it's first order or second order. if its second-order system determines if it's undamped, underdamped, critical damped, or overdamped. 𝑥(0) = 2, 𝑥̇(0) = 3; 𝑢(𝑡) 𝑖𝑠 𝑢𝑛𝑖𝑡 𝑠𝑡𝑒𝑝 𝑓𝑢𝑛𝑐𝑡𝑖𝑜𝑛 (ℎ𝑒𝑎𝑣𝑖𝑠𝑖𝑑𝑒(𝑡)) d^2x/dt^2 + 8 dx/dt+ 25x= 10 u(t) note: please don't solve it if you don't do all the following steps.
