5 0

Answer:

Operating system

Explanation:

An interrupt is the signal sent to the processor that interrupts the current process. It may be generated by a hardware device or a software program.With each interrupt the CPU hardware does exactly the same thing, which is what enables operating systems to take control of the current user operation.

Find the inverse function of f(x)= 1+squareroot of 1+2x
Svetllana [295]

Answer:

Therefore the inverse function of  f(x)=1+\sqrt{1+2x} is \frac{x^2-2x}{2}

Explanation:

We need to find the inverse of function f(x)=1+\sqrt{1+2x}

Function Inverse definition :

\mathrm{If\:a\:function\:f\left(x\right)\:is\:mapping\:x\:to\:y,\:then\:the\:inverse\:functionof\:f\left(x\right)\:maps\:y\:back\:to\:x.}

y=1+\sqrt{1+2x}\mathrm{Interchange\:the\:variables}\:x\:\mathrm{and}\:y

x=1+\sqrt{1+2y}

\mathrm{Solve}\:x=1+\sqrt{1+2y}\:\mathrm{for}\:y

\mathrm{Subtract\:}1\mathrm{\:from\:both\:sides}

1+\sqrt{1+2y}-1=x-1

Simplify

\sqrt{1+2y}=x-1

\mathrm{Square\:both\:sides}

\left(\sqrt{1+2y}\right)^2=\left(x-1\right)^2

\mathrm{Expand\:}\left(\sqrt{1+2y}\right)^2:\quad 1+2y

\mathrm{Expand\:}\left(x-1\right)^2:\quad x^2-2x+1

1+2y=x^2-2x+1

\mathrm{Subtract\:}1\mathrm{\:from\:both\:sides}

1+2y-1=x^2-2x+1-1

\mathrm{Simplify}

2y=x^2-2x

\mathrm{Divide\:both\:sides\:by\:}2

\frac{2y}{2}=\frac{x^2}{2}-\frac{2x}{2}

\mathrm{Simplify}

y=\frac{x^2-2x}{2}

Therefore the inverse function of f(x)=1+\sqrt{1+2x} is \frac{x^2-2x}{2}

2-Write test programs in java to determine the scope of a variable declared in a for statement. Specifically, the code must dete
ankoles [38]

Answer:

See Explaination

Explanation:

public class testscope

{

//start of main function

public static void main(String[] args)

{

//varible declration

int i;

int x;

//loop for 10 times

for(i=0; i<10; i++)

{

//initialize value of x to 10

x = 10;

}

//the scope of variable x is visible outside of for loop

System.out.println("The value of x is: "+x);

}

}

See attachment for sample output

nb:

You can clearly see in the output of Java program the value of x is not printed and program return errors. It means the variable x declared inside for loop does not has scope outside the for loop.

Which decimal number is equivalent to this hexadecimal number?<br> F8
emmainna [20.7K]

Explanation: The numbers in a hex are the same as decimal numbers: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. The big difference between a hex and a decimal is that a hex also contains letters. These letters are: A, B, C, D, E, F. A hex number can be represented using a subscript of 16.

C++
vichka [17]

Answer:

#include <iostream>

#include <map>  

using namespace std;

int main()

{

   map<int, int> numbers;

   cout << "Enter numbers, 0 to finish" << endl;

   int number;

   while (true) {

       cin >> number;

       if (number == 0) break;

       numbers[number]++;

   }

   for (pair<int, int> element : numbers) {

       std::cout << element.first << ": occurs " << element.second << " times" << std::endl;

   }

}

Explanation:

One trick used here is not to keep track of the numbers themselves (since that is not a requirement), but start counting their occurrances right away. An STL map< > is a more suitable construct than a vector< >.
