Homework Statement x + y+ z = 0 3x + 2y -2z = 0 4x + 3y -z = 0 6x + 5y + z = 0 Homework Equations The Attempt at a Solution I put the equations into a matrix and reduced to RREF. This is what I end up with: x - 4z = 0 y + 5z = 0 The other two rows in the matrix are all...

That explains it very well! I think I was just getting a little confused. Thanks very much!

Homework Statement This is probably a very dumb question, but I just can't wrap my head around what I'm supposed to be doing. The question is: "Determine whether the set is a subspace of R3: All vectors of the form (a,b,c) where a = 2b + 3c" Homework Equations u + v is an...

Homework Statement Create the design for a sequential circuit that counts 0-5 using only D flip-flops. Your designs should include a state diagram, state table, stated equations, and input equations. Additionally, draw the circuit diagram that represents your 0-5 counter. Your design...

A better question would be, what is the correct way to search an ArrayList for a specific object?

Homework Statement I'm working on a program that uses an ArrayList to hold a collection of UserID objects (which contains the first and last names, plus username and password). When I add a new UserID to the list, I want to check to make sure that it is not already there. This is the error...

I figured it out! Thanks! :)

Homework Statement I just have a quick question and hope I can ask it clearly. If I am writing a constructor for a class that takes in one value as an argument, but the value is two words, how can I extract the first and second word? For example, if I wrote a class called Name and my...

Homework Statement This is my assignment: (Sorry, it's a little long) You are required to write a UserID Java class to be used when generating and storing the user id and password for a new user of a system. At a minimum, each UserID object should store a first name, last name, user id, and...

Homework Statement Three positive particles of equal charge, +11.5 µC, are located at the corners of an equilateral triangle of side d = 13.0 cm (Fig. 16-50). Calculate the magnitude and direction of the net force on each particle. Image is here...

Sorry for the confusion! I think I figured it out. I'm not sure why I was having so much difficulty.

Sorry, I forgot to say that the language is Pep/8 (virtual computer). Not sure if that tells you anything, but that is the whole problem. I am given 5 answer choices: a. A2 11 b. A2 12 c. 00 02 d. 11 00 e. 00 FF And I know the answer is A. That's all the information I have. The...

Homework Statement (the language is Pep/8) Given the following state of memory (in hexadecimal) match the problem to the solution shown: 0001 A2 0002 11 0003 00 0004 FF What are the contents of the A register after the execution of this instruction? C1 00 01 I know that the answer is...

Thanks for all of your help! The homework is closed, so I can't see what the right answer is, but I will ask my teacher! And now I know how to work it if it shows up on the test! Thanks again!

Homework Statement What should be the spring constant k of a spring designed to bring a 1260 kg car to rest from a speed of 88 km/h so that the occupants undergo a maximum acceleration of 5.0 g? Homework Equations F=ma v2=v02 + 2a(x-x0 F=-kx The Attempt at a Solution...
