Question Does crime pay? The FBI Standard Survey of Crimes showed that for about 80% of all property crimes (burglary, larceny, car theft, etc.), the criminals are never found and the case is never solved.† Suppose a neighborhood district in a large city suffers repeated property crimes, not always perpetuated by the same criminals. The police are investigating seven

required solution   Intro Survey of Math Project \#2: Modeling with Functions The Population and Housing Census takes place every ten years and is designed to count every resident in the United States. The data collected by the census determine the number of seats assigned to each state in the U.S. House of Representatives and the amount of federal funds provided to local communities. In addition, census data guide infrastructure improvements as well as where and when to build schools and hospitals. You are tasked with analyzing the following census data for three states. Based on the data, answer the following questions in a separate word document, which you will upload to Canvas. Note: You will not receive any credit for answers without explanations. Please provide a paragraph that explains your methods and all of your work for each item listed below. 1. Create three different graphs for each set of data. (nine graphs total). For example, you may use a bar graph, a scatterplot, a line graph, or a circle graph. What do you notice about the data? Compare and contrast the sets of data. 2. Which model would best represent each set of data: linear, quadratic, or exponential? Explain your reasoning based on your graphs. 3. Determine the average rate of change for each set of data from 1910 to 2020. What do you notice? Compare and contrast the growth rates for the states. How do you think these growth rates will impact government allocations for each state? 4. Determine an exponential model for the states with the two fastest growth rates. Explain your work. Note: The y-intercept equals the value provided for 1910. Thus, for the year \( 1910, x=0 \). 5. Use your exponential models to predict the populations for these two states for the year \( 2030(x=120 \), the number of years since 1910). Explain your work. Do your predictions seem reasonable? Explain your reasoning. Note: This project will be submitted to Turnitin to check for plagiarism. Please ensure this work represents your original calculations, methods, and analysis.

Part 3 Bracket Evaluator (12\%) DataAnalysis Class DataAnalysis class checks whether a list of data is symmetrical (you can use Queue and Stack Classes). DataAnalysis class has an "bracketEvaluator" method. It returns true whether opening and closing bracket and brace pairs match up inside any given string.

MATHS 2106 Differential Equations for Engineers II Assignment 2 Due: 5:00 pm Tuesday 6 April When presenting your solutions to the assignment, please include some explanation in words to accompany your calculations. It is not necessary to write a lengthy description, just a few sentences to link the steps in your calculation. Messy, illegible or inadequately explained solutions may be penalised. The marks awarded for each part are indicated in boxes. This assignment has 8 questions, for a total of 24 marks. Variation of parameters Consider the variable coefficient linear second order non-homogeneous ODE zy" + xy +(22 - ) = 2 for => 0. (1) 1 1. Write down the associated homogeneous equation. 6 2. Show that y(x) = r-1/2 cost and 12() == -1/2 sin = are solutions of the associated homo- geneous equation. 2 3. Use the Wronskian test to determine if y: and ya are linearly independent for x > 0. 4. Write down the solution y(x) of the associated homogeneous equation. 5. Use the formulas in the course notes for the method of variation of parameters to find a particular solution 3p() of equation (1). Hint: you will need to re-urite the ODE in standard form in order to identify the non-homogeneous term in the formulas. 6. Write down the general solution to equation (1). 7. Find the solution to equation (1) that satisfies the initial conditions (T) = -1/2 and (x) = 0. 2 8. Use Matlab to plot the solution to the IVP in 7 for 1 S S 30. Attach the plot to your assignment solution, and describe the behaviour of y(x) as : +0.

Need Help with Question D,E,F A typical magnetic field in sunspots (highly magnetized regions on the surface of the sun) is 0.300 T. For a proton (charge +1.60 x 10-19 C, mass 1.67 x 10-27 kg) moving at 1.25 x 104 m/s in a direction perpendicular to such a field, find the radius of its circular orbit. Express your answer with the appropriate units. R = 4.35*10-4 m Submit Previous Answers Correct Part D In the situation of the previous problem, suppose the 0.300 T magnetic field is in the +y-direction and the proton's motion is not perpendicular to the field: initially its velocity has components v. = 1.00 x 104 m/s, vy = 7.50 x 10 m/s, v2 = 0. Find the radius of the proton's helical path. Express your answer with the appropriate units. 1: HÅR O 2 ? R= Value Units Part E Find how far the proton moves along the helix axis per revolution.
