(c) For any two natural numbers $n, m \in \mathbb{N}$ so that $n$ divides $m$, show that (i) The relation $\equiv_m$ of congruence modulo $m$ is a refinement of the relation $\equiv_n$ of congruence modulo $n$. (ii) There is a well-defined function $g: \mathbb{Z}/m \to \mathbb{Z}/n$ that maps $[a]_m \in \mathbb{Z}/m$ to $[a]_n \in \mathbb{Z}/n$.

Assume that there is a Turing machine that decides the language $L_1 = \{w \in \{0, 1\}^* \mid w \text{ contains the same number of 1s as 0s}\}$ . Using closure results for Turing-decidable languages, show that the language $L_2 = \{w \in \{0, 1\}^* \mid w \text{ contains more 1s than 0s}\}$ is Turing-decidable.

10. For this inclined plane question, m? = 5.0 kg and m? = 20.0 kg. The plane is inclined by 30° and the coefficient of kinetic friction between m? and the plane is ? = 0.150. a. Draw the forces acting on each mass. (5 pts) b. Find the acceleration of m?. (10 pts) $\vec{a}$ = 0.942 m/s² down ramp c. Find the tension in the rope between the two masses. (10 pts) d. If m? slides for 1.00 m, how much work is done by (10 pts) friction? $\begin{array}{l}c)\ T_1 = m_1g = (5.0 kg)(9.80 m/s^2) = 49 N \\ T_2 = m_2gx + f_k = 9.42 + (0.150)(9.42) = 10.8 N \\ m_2g = (20.0 kg)(0.942 m/s^2) = 18.84 \\\end{array}$ $\begin{array}{l}d)\ \Delta x = 1.00 m \\ Work = F \Delta d \\ W_{friction} = \mu_k m_2 g_x \Delta d = (0.150)(9.42)(1.00 m) = -1.41 J\\end{array}$

(A) Find the period of its motion. (B) Determine the maximum speed of the block. A block-spring system that begins its motion from rest with the block at x = A at t = 0. (C) What is the maximum acceleration of the block? (D) Express the position, velocity, and acceleration as functions of time in SI units. SOLVE IT (A) Find the period of its motion Conceptualize: Study the figure and imagine the block moving back and forth in simple harmonic motion as a stapler from a strong rubber band. Categorize: The block is modeled as a particle in simple harmonic motion. We find values from equations developed in this section for the particle in simple harmonic motion model, so we categorize this example as a substitution problem. Use the equation to find the angular frequency of the block-spring system: k = 8.20 N/m m = 285 x 10^-3 kg Use the equation to find the period of the system: T = 2π√(m/k) = 1.16 s (B) Determine the maximum speed of the block. Use the equation to find Vmax: Vmax = Aω = (7.35 x 10^-2 m)(0.3941805 s^-1) = 0.0289 m/s (C) What is the maximum acceleration of the block? Use the equation to find amax: amax = 2Aω^2 = 2(7.35 x 10^-2 m)(0.3941805 s^-1)^2 = 0.0114 m/s^2 (D) Express the position, velocity, and acceleration as functions of time in SI units. Find the phase constant from the initial condition that x = A at t = 0: x0 = Acos(0) = A = 0 Use the equation to write an expression for x(t): x = A cos(ωt + φ) = 0.05 cos(1.16t + φ) Use the equation to write an expression for v(t): v = -Aω sin(ωt + φ) = -0.05(0.3941805) sin(1.16t + φ) Use the equation to write an expression for a(t): a = -Aω^2 cos(ωt + φ) = -2(7.35 x 10^-2 m)(0.3941805 s^-1)^2 cos(1.16t + φ)

Quality Corporation sells a single product, an adjustable sun visor, whose selling price is $20 per unit and whose variable expense is $6 per unit. The company's monthly fixed expense is $24,000. Required a. Calculate the company's break-even point in unit sales. b. Calculate the company's break-even point in dollar sales. c. The company is considering a strategy whereby they improve the quality of the product, increasing costs by $2/unit and expanding advertising, increasing marketing costs by $7,000. They project that if they were to take these two actions, they could generate 2,500 additional sales units. Should they adopt this strategy?
