2^8= 256 11. Given 4 bits of mask for the network portion, how many subnets are available? 2^4= 16 12. Explain the reasoning behind the concept of “subnet zero.” 13. For a network address, what does the host portion of the address appear as in binary representation?
Write assignment statements that perform the following operations with the variables a, b, and c. a) Adds 2 to a and stores the result in b * b=a+2 b) Multiplier b times 4 and stores the result in a * a=b*4 c) Divides a by 3.14 and stores the result in b * b=a/3.14 d) Subtract 8 from b and stores the result in a * a=b-8 4. Assume the variables result, w, x, y, and z are all integers, and that w=5, x=4, y=8, and z=2. What value will be stored in result in each of the following statements? a) Set result = x + y * 12= x + y b) Set result = z + 2 * 4=z * 2 c) Set result = y / x * 2=y / x d) Set result =y – z * b=y – z 5. Write a pseudocode statement that declares the variable cost so it can hold real numbers.
1. Factor a trinomial whose leading coefficient is 1. Pick any one of the problems and solve the trinomial. If the trinomial is prime, state this and explain why. a. x2+8x+15 b. x2–4x –5 c. x2–14x+45 2.
1024 is the number of items top to bottom in a grid on the screen. 20. (A), (B) – Information that identifies each individual pixel on the computer display. A binary code for each pixel, defining its color. List the Words Inside Acronyms 1.
Begin by writing the corresponding linear equations, and then use back-substitution to solve your variables. 10–1301–8001 159–1 x,y,z=( , , ) 10–1301–8001 159–1 = x-13z=15y-8z=9z=-1 = x-13(-1)=15y-8(-1)=9z=-1 = x=2y=1z=-1 x,y,z=(2 , 1 , -1) Determinants and Cramer’s Rule: 2. Find the determinant of the given matrix. 8–2–12 8–2–12 = 8*2 - (-1)(-2) = 16 - 2 = 14 3. Solve the given linear system using Cramer’s rule.
Unit 1 True/False Questions Indicate whether the following statements are true or false on the student answer sheet. 1) At its simplest, a database can be seen as a collection of related data. a. T 2) A delimited file is a file where the length of the file is limited. b. F 3) A delimited file is one in which the data is separated by a character such as a comma. c. T 4) All fixed length files are of the same length.
Undoubtedly, the Internet has led to a spectacular outburst of human innovation, but its dynamism has frustrated any effort to regulate it, hold cybercriminals responsible, and resolve conflicts (Mueller, 2010, pp. 175-176). What makes matters more complicated is the fact that several nations and jurisdictions also seek justice and someone to be held responsible when their legal principles or societal standards are violated (Thierer & Crews, 2003, p. 16). New, innovative technologies can pose problems for policymakers, who often try to control these when they have little knowledge regarding them. The Internet has been particularly challenging for drafting successful and effective policies due to its affordability, accessibility, and inclusiveness.
The sides of the triangle that meet at the right angle are labeled as sides (a) and sides (b). The long side of the triangle is labeled (c) and this is the hypotenuse. The hypotenuse is the side of a triangle that is opposite the right angle (http://www.mathwarehouse.com). A few example of a Pythagorean Triples and Theorem are as follows: 1) 8, 15, and 17. You would equate this as 82 x 152 = 172.
Next it’s a simple matter of multiplication to determine the area of the rectangle. 12.25 cm x 3.25 cm = 39.8125 cm2 In each measurement the last digit represents the uncertainty or the estimate; remember the ruler was graduated in millimeters, the 5 was simply an estimate of the distance between the .2 and .3 graduations. The 5 was chosen because you interpreted the distance to be halfway between the 2 however another individual taking the same measurements may have interpreted the
If you do use Packet Tracer you might wish to demonstrate that your combined addressing and routing scheme works by pinging between the 2 PCs in both directions. Whether you choose to use Packet Tracer or not, write a short report of no more than 1000 words
