• ### Looking for a new 4k TV. Is Samsung UN55MU6490 a good buy?

So my current TV is a waaaay outdated and I am shopping around for a new TV which will be my first 4k TV and Im considering getting a UN55mu6490 4k Curved TV locally off Craigslist for \$500

Im just wondering if its a good buy considering I will eventually get a PS5 and I also plan on using this TV as a monitor for my laptop for certain video editing projects

Since I dont want to break the bank and \$500 is right at my budget, is this a good buy for my first 4k TV and my needs?

• ### Car is not registered. Can I pass toll booth without violation?

If I drive through a cashless booth in NY/NJ with a car that is not registered but the plates are in my name but for a Sentra (not the car the plates will be used on going through the booth, which is a Hyundai). Can I get in trouble for this?

• ### Is this a good buy? Chevrolet Impala LTZ 2008 3.9L V6 - 102k miles for \$3,800?

Hi All,

What are your thoughts on a 2008 Chevy Impala LTZ with 102k miles? Car looks well maintained and owner claims the car is Very clean & good condition:

Original Mileage, clean title, leather w/ tan interior, power locks and windows. Going to see it tomorrow.

Don't know much about Chevy Impala's but does this sound like a good deal for the car? (or peraps \$3,500?)

I drive approx. 15k miles a year (mostly highway) so is the gas mileage good?

• ### Recursive Excersice running into a problem (C# Language)?

I am having trouble printing the second half of what is required from the exercise. The code basically asks to input two number and output their sum, but before the sum is outputted, the first number needs to be recursively subtracted by 1 till 0 then recursively added by 1 till it reaches its original value. Example:

//Input

//Output

From start of body: 4 6

From start of body: 3 6

From start of body: 2 6

From start of body: 1 6

From start of body: 0 6

From end of body: 1 6

From end of body: 2 6

From end of body: 3 6

From end of body: 4 6

The sum of 4 and 6 is 10.

My code only prints out the From Start of Body part of the code, not the From End Of Body part, what could be the issue? Here's my code:

using System;

class RecursiveHomework

{

static void Main()

{

int num1, num2;

Console.Write("Enter the first number: ");

Console.Write("Enter the second number: ");

Console.WriteLine();

int sum = num1 + num2;

RecursiveHomework Recursion = new RecursiveHomework();

Recursion.RecSum(num1,num2);

Console.WriteLine("The sum of " + num1 + " and " + num2 + " is " + sum);

}

public int RecSum(int a, int b)

{

int c = -1*a;

if(a>=0)

{

Console.WriteLine("From Start of body: " + a + " " + b);

return RecSum(a-1, b);

}

else if(a>=c)

{

Console.WriteLine("From End of Body: " + a + " " + b);

return RecSum(a+1, b);

}

return 0;

}

}

• ### My Samsung Vibrant got alittle wet from a Rainstorm. What do I do?

Hey guys, I'm really upset. The other day I was riding my bike home in the rain and had my phone in my bag which, or the most part, did its thing keeping my phone dry from the rain. I used it to make a quick call and it got alil wet like it normally would when trying to make a call in the rain. Then, 15 minutes later when I got home, I noticed the phone was off and did wanna turn on even when plugged into the usb. I took the battery out and all that, let it dry over night dis assembled, and it still wont turn on at all. The watermark on the batter is perfectly white and the phone wasent even that much exposed to the water from the rain. WHAT CAN I DO! I have a flex pay account with tmobile so iunno if I can upgrade and the phone was bought of someone from my school which im assuming has an expired warranty or voided cuz the phone was "jailbroken". Iunno what to do guys, how much would a water damage repair be, etc, etc. Someone help!

• ### I have several Linear Algebra questions regarding a midterm that is coming up:?

1) Determine whether the columns of this matrix are linearly independent.

1, 1, 0, 0

1, 1, 0, 1

1, 1, 0, 1

2, 1, 1, 1

I think the system is inconsistent because when row reduced we get:

1, 0, 1, 0

0, 1, -1, 0

0, 0, 0, 1

0, 0, 0, 0

The third row results in 0=1, which is not true, hence an inconsistent solution that cannot deterine linear independency or depandancy, right? I need clarification on this.

Also: 2) Find a pair of 2X2 matrices that form counter example to the relation (A+B)^2 = A^2 + 2AB+ B^2

3) Prove that for every nxn matrix A(1n + A)^2 == 1n + 2A + A^2

AND 4) T is a linear transformation of u, v, and w are vectors. Suppose you know that T(v) = w and T(u) = 0. Find an expression that equals T(4u + 7v) that makes no mention of T.

PLEASE HELP ASAP. I need to understand the last 3 thoroughly so an in depth explanation is much appreciated.

• ### What is the solution set for the following system of linear equations using Augmented Matrices and?

Row operations. The system is:

X1 - 3(X3) = 8

2(X1) - 2(X2) + 9(X3) = 7

+ X2 + 5(X3) = -2

I know the augmented Matrix is:

1 0 -3 8

2 -2 9 7

0 1 5 -2

The rest of the matrices using the row operations

1 0 -3 8

0 -2 15 8

0 1 5 -2

then:

1 0 -3 8

0 -2 15 -8

0 0 25 -12

Using row operations I end up getting X3 is -12/25 but I feel as if I'm wrong...

Is the the answer maybe that there is no solution due to Row 1 and Row 2 equaling 8 and -8 respectively and using row operations, we can make Row 2 = 0, hence producing an inconsistent solution since there would still be variables present?

• ### Why am I getting compiling errors for this simple C program?

include <stdio.h>

int main()

{

printf(“Goodbye, cruel world!”);

return(0);

}

That is the original code, now look at the errors:

C:\Dev-Cpp\GOODBYE.c.c In function `main':

4 C:\Dev-Cpp\GOODBYE.c.c stray '\147' in program

4 C:\Dev-Cpp\GOODBYE.c.c `Goodbye' undeclared (first use in this function)

(Each undeclared identifier is reported only once

for each function it appears in.)

4 C:\Dev-Cpp\GOODBYE.c.c `cruel' undeclared (first use in this function)

4 C:\Dev-Cpp\GOODBYE.c.c syntax error before "world"

4 C:\Dev-Cpp\GOODBYE.c.c stray '\' in program

4 C:\Dev-Cpp\GOODBYE.c.c stray '\148' in program

CAN SOMEONE HELP ME? I can't even get a simple "Hello, World" application to run!

Ok. So I found what I believe is a 3g iphone. Its funny because I found it with no sim card and its stuck on that emergency call screen. When I try to connect it to iTunes, it says the sim card inserted is not supported and it doesnt let me restore the phone or update it or anything. I have tmobile so I want to jailbreak it but I apparently need to know which version it is but cant even find out. I tried using redsnow and it looks like its working but then it just goes back to the same screen. What do I have to do to get this thing jailbroken and unlocked for tmobile??
