Then read carefully the two essays in our Course Reserves – "Drugs" by Gore Vidal and "The Case for Slavery" by A. M. Rosenthal - and point out an example of each type of discourse: an instance of persuasion that seems humane and fair-minded and an instance of persuasion that seems propagandistic (i.e., deceptive or manipulative).

The fact that children can take a form of communication that lacks a consistent grammar and turn it into one that has consistent rules illustrates that Vygotsky was correct concerning the role of culture in language. Chomsky was incorrect concerning the origins of grammar. Children acquire language through reinforcement by adult speakers of the language there is a built-in, universal grammar.

Solve the following system of equations by using the inverse of the coefficient matrix if it exists and by the echelon method if the inverse doesn't exist. x + 2y = 15 -3x+3y=0 What is the inverse of the coefficient matrix? A. The inverse matrix is $\begin{bmatrix} 1 & 2\\ -3 & 3 \end{bmatrix}$ (Type a matrix, using an integer or simplified fraction for each matrix element. Do not factor out a scalar multiple.) B. There is no inverse of the given matrix.

thermometer. A sample of brass, which has a specific heat capacity of 0.375 J$\cdot$g$^{-1}$$\cdot$$^{\circ}$C$^{-1}$, is put into a calorimeter (see sketch at right) that contains 100.0 g of water. The brass sample starts off at 90.4 $^{\circ}$C and the temperature of the water starts off at 19.0 $^{\circ}$C. When the temperature of the water stops changing it's 22.5 $^{\circ}$C. The pressure remains constant at 1 atm. Calculate the mass of the brass sample. Be sure your answer is rounded to 2 significant digits. insulated container water sample X 5 a calorimeter

CS4700/6700 Homework 1 (A) Write the following four queries, Q1--Q4, in relational algebra, concerning the following relations: SUPP(SNAME,STREET, CITY) SP(SNAME,PNAME,PRICE) PART(PNAME,COLOR) The underlined attributes form the primary keys of the corresponding relations. SUPP stores the names, streets and cities of suppliers; PART stores the names and colors of parts; a tuple (s,p,c) in SP says that supplier s can supply part p at price c. SNAME of SUPP is fk referencing SP, and PNAME of PART is fk referencing SP. Q1. Find the names of suppliers who supply both 'red' parts and 'green' parts. Q2. Find the names of suppliers who supply some 'red' parts but do not supply any 'green' parts. Q3. Find the names of suppliers who supply all of the 'blue' parts. Solutions without "division" are preferred. Q4. For each supplier, list the name of the supplier and the number of 'blue' parts the supplier supplies. In Q2, "a supplier does not supply any 'green' parts" means that there are no green parts supplied by the supplier. (B) Show the results of relational algebra queries Q1 and Q6 on Slide 6.57 (L4RACh08.pptx) when applied to the database state on Slide 6.7 (L4RACh08.pptx). You need to "execute" the multi-step relational algebra queries. You should also show the results of the temporary relations in those multi-step queries. You can do this on more queries to help you learn the material. (C) Answer the following questions: C.1. What is the difference between a database schema and a database state? C.2. Describe the three-schema architecture. Why do we need mappings between schema levels? How do different schema definition languages support this architecture? C.3 What is the difference between a key and a superkey? There are many more questions like C.1, C.2 and C.3 in the book. You should work out as many exercise questions as possible to help you learn and prepare for the exams. ^(************)
