13 of 20 It is said that in a perfectly competitive market, raising the price of a firm's product from the prevailing market price of $169.00 to $189.00, will likely cause the firm to reach its shutdown point immediately will cause the firm to recover some of its opportunity costs could likely result in a notable loss of sales to competitors is a sure sign the firm is raising the given price in the market

Anna throws a ball in the air from her balcony. The following equation models the height of the ball, in meters, after $ t $ seconds. \[ h(t)=-5 t^{2}+9 t+80 \] Anna wants to rewrite the equation to determine after how many seconds the ball hits the ground. Use this situation to complete the following statements. The function $ \square $ reveals that the balls $ \square $ above the ground will be $ \square $ meters after seconds.

Problem Statement Suppose we have a uniform rod of mass M and length L that can pivot about one end. The other end is attached to a horizontal spring with constant k that is affixed to a wall. The spring is neither stretched nor compressed when the rod hangs straight down. Assume that the rod's angle from the vertical is always small and that the spring does not bend or bow. L k M A. Draw a free body diagram for the pendulum and be sure to explicitly label any angles, forces, locations of forces, center of mass, etc. For full credit, students will follow the procedure for drawing a free-body diagram laid out in the document "A guide to free-body diagrams." B. Using the forces identified in your free body diagram, write down Newton's law of torque for the physical pendulum. C. Derive an equation of motion for the pendulum. See Model 15.1 "simple harmonic motion" from your textbook (Ch. 15.6, pg. 406). Hint: You may need to look up some trigonometric identities and recall the small angle approximation. D. Deduce a symbolic expression for the angular frequency $\omega$ of the pendulum using your equation of motion. Again, see Model 15.1 and Ch. 15.6 of the textbook. E. Assess the validity of the expression you found for the angular frequency $\omega$ by examining at least 3 limiting cases in terms of the variables k, g, L, and m. To do so, first comment in one sentence what you expect to happen if k, g, L, or m increase/decrease. Then show that your symbolic expression for the angular frequency $\omega$ backs up your intuition when this change is made.

This is the transformed equation in terms of Z(s). Solving for Z(s) will give me the Laplace transform for \newline x(t). \newline \newline Z(s) = \frac{300}{s^2 + \frac{2\pi^2}{7200}} - \frac{9000s}{s^2 + \frac{2\pi^2}{7200}} \newline \newline Using the following inverse Laplace transform \newline \newline \frac{1}{s^2 + \omega^2} = \frac{1}{\omega}sin \omega t \newline \frac{s}{s^2 + \omega^2} = cos \omega t

Micro-Assignment #2: Importing and Using a Library Write a Python script in the cell provided below that imports the NumPy library and gives it the name "np". Then use the NumPy sine function to evaluate the sine of 67°. The numpy sin function assumes the input to be in radians. You can use NumPy to convert your angle from degrees to radians using the numpy.deg2rad. Assign the result to the variable Answer1.

Problem 4 An analog signal with bandwidth of 5KHz is to be sampled at a rate of 12,000 samples/ we need an antialiasing filter with no oversampling allowed. The order of the filter is given as $N = \frac{4.5}{\log_{10} (1 + \frac{\Delta F}{F_{pass}})}$ Where $\Delta F$ is the transition bandwidth & $F_{pass}$ is the pass band edge frequency. (a) find $F_{pass}$, $F_{stop}$ & $\Delta F$, sketch the filter frequency response. (b) calculate the order of the filter required

Problem 3. (10 points) When word about the recursion theorem reached Lem E. Hackett, he immediately implemented it in code. His associate, Ben Bitdiddle, who insists the recursion theorem is too bizarre to be true, used Lem's implementation to create the following program: TM B: On input x 1. Construct own description (B) 2. Run B(x): If it accepts then REJECT else if it rejects then ACCEPT "A program like this that contradicts itself cannot exist," claimed Ben. Therefore, your code cannot possibly be right, and so the recursion theorem is false. "Let's run the program and see what happens," said Lem who prefers running code to proofs. What is the result of running Ben's program? What was the mistake in Ben's reasoning (other than thinking that the recursion theorem is false)?
