Criminal Justice: Crime Prevation

Name Professor Course Date Criminal Justice: Crime Prevention Question 1: The number n of incidents of family violence requiring police response appears to be related to d, the money spent on crisis intervention, by the equation: n = 430 - 0.005d. What expenditure would reduce the number of incidents to 350? Solution n, represents the number of incidences that needs response from the police d, is the expenditure on crisis intervention We know that: n = 430 - 0.005d Therefore: Number of incidences n =350 Hence: 350=430-0.005d (Simmons 28) Rearranging values: 350-350+0.005d=430-350-0.005d+0.005d (Larson and Anne 35). 0.005d=800.005d0.005=800.005 (Leff 56)....

How can maths be used in code cracking and how does the methodology differ?

Name: Professor: Subject: Date: USE OF MATHEMATICS IN CODE BREAKING INTRODUCTION Human beings have always needed for secret communications through public channels. The message has to be transformed to form that cannot be read to facilitate secret communication. The message that is unreadable is called a coded message. In technical terms, the original message is the called the plaintext while the unreadable message is called the ciphertext. The conversion of plaintext to ciphertext is called encryption while the conversion of ciphertext to plain text is called decryption. The process of encryption and decryption is called cryptography. The process of cryptography involves coming up with a...

QUIZ 1

Quiz 1 Name Institution Course Instructor Date (i) Consider a graph of shown below. Find the slope and equation of the line joining A and B. Let A (1,-10) be (x1,y1) and B(-2,17) be (x2,y2). Slope is give by change in y/ change in x Thus in this case, it will be (y1-y2)/(x1-x2) = (-10-17)/ (1-(-2)) =-27/3 =-9 Equation of the line joining A and B Take any point in the line AB to be (x, y) and (1,-10) Then Slope remain the same thus, -9=(y+10)/(x-1) -9x+9=y+10 Thus y=-9x-1 Find the slope and equation of the line joining A and C. Let A (1,-10) be (x1,y1) and C(0,1) be (x2,y2). To find the slope= (y1-y2)/ (x1-x2) = (-10-1)/(1-0) = -11 Equation of the line AC will...

Harmonic Functions in Complex Analysis

Name: Instructor: Course: Date: Harmonic Functions If Ω denotes a set that is open in Ɍ3, then the real valued function u x, y, z on Ω characterized by a continuous second partials is declared harmonic if, and only if the Laplace ∆u=0 is identical on Ω. This is when the Laplace u is shown as ∆u= ∂2u ∂x2+ ∂2u∂y2+ ∂2u∂z2In the case of an open set Ω in Ɍ3, then a similar definition can be made. u will therefore, be harmonic only if; ∆u= ∂2u ∂x2+ ∂2u∂y2=0 on Ω. The following are basic examples of harmonic functions; u= x2+ y2- 2z2, Ω = Ɍ3u= 1r Ω = Ɍ3- (0, 0, 0) where r= x2+ y2+z2 . More to this, considering Ω, an open set in Ɍ3, the real...

Public school system should be required to wear school uniforms

Name Professor Course Date Public School System should be required to Wear School Uniforms Introduction School uniforms are the specific design for clothing designated to be worn by the students when attending their academic classes at the schools. Different public schools in the United States and their respective different grades have different school uniforms. However, that is no issue, what is important is that schools should be schools and rather not fashion shows. Since all students go and should go to school with one primary aim, gaining an education, creating uniformity amongst all students is also paramount (Brunsma 216). I, therefore, strongly support that the U.S. public school system...
