Tell what an array is and list two scenarios in which modeling data as a Java array (vs. another data type) would make sense.

Answer:

The definition including its context of this discussion is outlined in the following clarification portion.

Explanation:

  • An array seems to be a storage research method to collect a set number of constant weight. Whenever the array was indeed generated, the length including its array has been determined. Its period is set after development.
  • Depending mostly on array description, the array may contain data structures and even some objects in something like a class. For primitive data types, the individual values become located at contiguous locations throughout the store.

Scenario:

  • If we're to preserve a summary, we could use the appropriate array size.
  • An individual can however preserve an object list.

X = 1 if (A = 1 OR B = 1) OR (A = 0 AND B = 1
Gnoma [55]

Answer:

For question a, it simplifies.  If you re-express it in boolean algebra, you get:

(a + b) + (!a + b)

= a + !a + b

= b

So you can simplify that circuit to just:

x = 1 if b = 1

(edit: or rather, x = b)

For question b, let's try it:

(!a!b)(!b + c)

= !a!b + !a!bc

= !a!b(1 + c)

= !a!b

So that one can be simplified to

a = 0 and b = 0

I have no good means of drawing them here, but hopefully the simplification helped!

Find the equation of a line which has 10 points the following two coordinates: (4, 0) and (3, 4)​
alex41 [277]

Answer:

The equation of the line is y = -4·x + 16

10 points on the line include;

(0, 16), (1, 12), (2, 8), (3, 4), (4, 0), (5, -4), (6, -8), (7, 12), (8, -16), (9, -20), and (10, -24)

Explanation:

The given points through which the line passes are;

(4, 0) and (3, 4)

The slope, 'm', of the line is given as follows;

Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}

Therefore, the slope of the line is (4 - 0)/(3 - 4) = -4

In point and slope form we can get;

\dfrac{y-0}{x-4} = -4

The equation of the line in point and slope form is therefore;

y = -4·(x - 4) = -4·x + 16

The equation of the line in slope and intercept form is

y = -4·x + 16

10 points on the line are obtained using the equation of the line and the desired x-values input into cells on MS Excel and presented here as follows;

(0, 16), (1, 12), (2, 8), (3, 4), (4, 0), (5, -4), (6, -8), (7, 12), (8, -16), (9, -20), and (10, -24)

Given: an int variable k, an int array current Members that has been declared and initialized, an int variable memberID that has
Alekssandra [29.7K]

Answer:

The c++ program is given below. Nothing is displayed as per the question.

#include <iostream>

using namespace std;

int main() {    

   // declaration and initialization of integer variables

   int k, memberID = 12, nMembers=5;

   bool isAMember;    

   // declaration and initialization of integer array

   int currentMembers[] = {12, 34, 56, 78, 90};    

   for(k=0; k<nMembers; k++)

   {

       if(memberID == currentMembers[k])

       {

           // when member is found in the array, the loop is exited using break

           isAMember = true;

           break;

       }

       else

           isAMember = false;

   }    

   return 0;

}

Explanation:

The program begins with declaration and initialization of integer variables and followed by initialization of the array holding the id of all the members.

The Boolean variable is declared but not initialized.

int k, memberID = 12, nMembers=5;

bool isAMember;

int currentMembers[] = {12, 34, 56, 78, 90};

After this, the array holding the id of the members is searched for the given member id. This is done using  a for loop and a if else statement inside the loop.

If the member id is present in the array, the variable isAMember is initialized to true otherwise it is assigned false.

When the variable isAMember is initialized to true, the break statement is used to exit from the loop.

for(k=0; k<nMembers; k++)

   {

       if(memberID == currentMembers[k])

       {

           isAMember = true;

           break;

       }

       else

           isAMember = false;

 }

The break is used since other values of id in the array will not match the given member id and the variable, isAMember will be initialized to false even if the given member id is present in the array. Hence, it is mandatory to exit the loop once the given member id is found in the array.

This program can be tested for different values of the id of the members and different sizes of the array.

Assume values 10, 20, 30, and 40 are entered in the cell range A1:A4. Cell A10 contains the formula: =A1+A2+A3+A4 and displays v
r-ruslan [8.4K]

Answer:

The formula and value to this question is "=A1+A3+A4+A5 with value 100"

Explanation:

The explanation of the given question as follows:

  • In question, it is defined that four cells that are "A1, A2, A3, and A4"  contains value that are "10, 20, 30, and 40".
  • To add these values we use addition formula that is "=A1+A2+A3+A4". it will give value 100.
  • If the user inserts a new row that is "A2" and assigns a value in the cell that is "50" so, we use the above formula that adds values with these values we also use the value "100".
