For two numbers, a & b, define the operation, "&" by: a&b = 2a(a-b)?

a). Find the value of 3 %26amp; 2


b). For what exact values of x is: 4 %26amp; x=42?


c). For what exact values of x is: x %26amp; 4 =42?

For two numbers, a %26amp; b, define the operation, "%26amp;" by: a%26amp;b = 2a(a-b)?
Just plug them in:





a) 2(3)(3 - 2) = 6





b) 4%26amp;x = 2(4)(4 - x) = 42





8(4 - x) = 42





32 - 8x = 42





and you should be able to finish it from there.





c) works pretty much the same as (b).
Reply:Kind of a confusing way to ask it, but I think I get what your asking...





Replace 'a' and 'b' with 3 and 2. Then you will have your answer! The rest of the questions follow after the first.

"unknown" does not seem read answers at all!

Reply:a) Is a 'plug and chug' problem. Just put the numbers in and chug out the answer.





b) and c) Also just substitution and simplification problems.





I'm reluctant to just do these for you. What would you learn that way?

Help me I have to define Humanities in to following questions?

A.) Art b.) Music c.) Architecture d. ) Philosophy e.) Literature


I have to write a paper and I did not recieve my book in time for class and help please. Tank you

Help me I have to define Humanities in to following questions?
Might be easier if I know what book you were supposed to use.





Humanities are the things that are unique to humans. Generally, that means self-expression and the ability to symbolize.





Each of those sub-disciplines of the humanities has its own bailiwick, so to speak. Art uses visual media; music uses auditory media, architecture uses construction media, and literature uses linguistic media. Philosophy is concered with pure thought.





Hope that helped a little.

About C programming. Please Help!?

OK, I want to write a programme which will ask the user to define the dimension of a 2D-matrix and then to input the matrix. How can I do that? And I think one can not define a 2D-array of undifine size. Is it correct or am I wrong?

About C programming. Please Help!?
Declare a two dimensional pointer for example :





int **x;





x = static_cast%26lt;int **%26gt;(malloc(sizeof(void *) * dimension x));


for ( i = 0; i%26lt;dimension x; i++)


{


x[i] = static_cast%26lt;int**%26gt;(malloc(sizeof(void) * dimension y));


}





You are ready to use x[i][j]
Reply:in C-99 the latest version - you can!!!!





char x[a];





is allowed in C-99.


But before that - like Ansi C, no, it is not allowed. But you can realloc. For example you malloc an array. if the value is not large enough then realloc!!!





Good luck
Reply:Ask for the dimensions of the array, then pass the dimensions to a function. Declare the array variable in this function, using the passed parameters to determine the size. Pseudocode:





main {


get dimX, dimY


inputArray(dimX, dimY)


}





inputArray(sizeX, sizeY) {


declare anArray[sizeX, sizeY]


}





Hope this makes sense.

For two numbers, a & b, define the operation, "&" by: a&b = 2a(a-b)?

a). Find the value of 3 %26amp; 2


b). For what exact values of x is: 4 %26amp; x=42?


c). For what exact values of x is: x %26amp; 4 =42?

For two numbers, a %26amp; b, define the operation, "%26amp;" by: a%26amp;b = 2a(a-b)?
a%26amp;b = 2a(a-b)


3%26amp;2 = 2*3(3-2)


3%26amp;2 = 6*1


3%26amp;2 = 6


So %26amp; = *





4x = 42


X=42/4


X= 10.5





x4 = 42


x= 42/4


x= 10.5
Reply:Somthing seems to be missing or maybe I am missing the boat here
Reply:a+b=2(a-b) =%26gt; a+b/a-b =2


4+x=42


x=42-4


x=38


or


4x=42 =%26gt;x=42/4 =%26gt;10.5
Reply:Do y'all ever think of reading the question?





The solution method is simple, just plug the numbers into the formula you are given, and solve. So:





a: 3%26amp;2=2*3(3-2)=6





b: 2*4(4-x)=42


32-8x=42


-8x=10


x = -10/8 = -5/4





c: 2*x(x-4)=42


x(x-4)=21


x²-4x=21


x²-4x+4=25


(x-2)²=25


x-2=±5


x=-3 or x=7

Dig





We all have a weakness


But some of ours are easier to identify.


Look me in the eye


And ask for forgiveness;


We'll make a pact to never speak that word again


Yes you are my friend.


We all have something that digs at us,


At least we dig each other


So when weakness turns my ego up


I know you'll count on the me from yesterday


If I turn into another


Dig me up from under what is covering


The better part of me


Sing this song


Remind me that we'll always have each other


When everything else is gone.


We all have a sickness


That cleverly attaches and multiplies


No matter how hard we try.


We all have someone that digs at us,


At least we dig each other


So when sickness turns my ego up


I know you'll act as a clever medicine.


If I turn into another


Dig me up from under what is covering


The better part of me.


Sing this song!


Remind me that we'll always have each other


When everything else is gone.


Oh each other....


When everything


Else is gone.

Set up the system of equations (3 equations total) with 3 variables (x,y,z) Define each variable....?

I dont want this to be solved, simply give me the 3 variables and the three equations, I can do the rest. Here is the problem:





A person takes three daily vitamin supplements, B,C and E, via three types of pills, regular, extra-strength, and fortified. Each regular pill contains 10 units of B, 20 units of C, and 20 units of E. Each extra-strength pill contains 20 units of B, 60 units of C, and 10 units of E. Each fortified pill contains 10 units of B, 20 units of C, and 40 units of E. HOW MANY PILLS of each type should be taken, in order to achied 50 units of B, 120 units of C, and 90 units of E.


Thank you very much!!!!!

Set up the system of equations (3 equations total) with 3 variables (x,y,z) Define each variable....?
Its not so hard if you break down the question. What are the constants? ans. B, C, and E


so what change in each equation - the question tells us that it is the strength of each pill. So lets call each pill x, y and z





so now you just need to figure out the equation - because it isnt that hard when you can see it - I'll just give you the first, and you can use that to figure out the rest.


x= regular pill = 10B + 20C + 20E


when you have the 3 pills equations then you can figure out how to get 50 units of B etc. I can see the answer to how many pills by just looking at the 3 equations written in a row - so its not that hard to see, once you've got them written down.
