Answer:

The main forces in a suspension bridge are tension in the cables and compression in the towers. The deck, which is usually a truss or a box girder, is connected to the suspension cables by vertical suspender cables or rods, called hangers, which are also in tension. I think this is the answer

Given an array as follows

slava [35]

Answer:

1) Method calcTotal:

public static long calcTotal(long [][] arr2D){
long total = 0;
for(int i = 0; i < arr2D.length; i++ )
{
for(int j = 0; j < arr2D[i].length; j++)
{
total = total + arr2D[i][j];
}
}
return total;
}

Explanation:

Line 1: Define a public method calcTotal and this method accept a two-dimensional array

Line 2: Declare a variable, total, and initialize it with zero.

Line 4: An outer for-loop to iterate through every rows of the two-dimensional array

Line 6: An inner for-loop to iterate though every columns within a particular row.

Line 8: Within the inner for-loop, use current row and column index, i and j, to repeatedly extract the value of each element in the array and add it to the variable total.

Line 12: Return the final total of all the element values as an output

Answer:

2) Method calcAverage:

public static double calcAverage(long [][] arr2D){
double total = 0;
int count = 0;
for(int i = 0; i < arr2D.length; i++ )
{
for(int j = 0; j < arr2D[i].length; j++)
{
total = total + arr2D[i][j];
count++;
}
}
double average = total / count;
return average;
}

Explanation:

The code in method calcAverage is quite similar to method calcTotal. We just need to add a counter and use that counter as a divisor of total values to obtain an average.

Line 4: Declare a variable, count, as an counter and initialize it to zero.

Line 11: Whenever an element of the 2D array is added to the total, the count is incremented by one. By doing so, we can get the total number of elements that exist in the array.

Line 16: Use the count as a divisor to the total to get average

Line 18: Return the average of all the values in the array as an output.

Answer:

3) calcRowAverage:

public static double calcRowAverage(long [][] arr2D, int row){
double total = 0;
int count = 0;
for(int i = 0; i < arr2D.length; i++ )
{
if(i == row)
{
for(int j = 0; j < arr2D[i].length; j++)
{
total = total + arr2D[i][j];
count++;
}
}
}
double average = total / count;
return average;
}

Explanation:

By using method calcAverage as a foundation, add one more parameter, row, in the method calcRowAverage. The row number is used as an conditional checking criteria to ensure only that particular row of elements will be summed up and divided by the counter to get an average of that row.

Line 1: Add one more parameter, row,

Line 8-15: Check if current row index, i, is equal to the target row number, proceed to sum up the array element in that particular row and increment the counter.

You’ve been hired to help a bank automate their deposit/withdrawal system! Your task is to write a Python program that interacts

mixer [17]

Answer: See below

Explanation:

Description: In this program, read-option from the user and based on that, perform the operation. And display the balance if the balance is negative.

transactions.py

balance = 1000

#read options from the user

option = input("Deposit or withdrawal: ")

amount = 0

#check if option is a withdrawal

if option == 'withdrawal':

amount = int(input("Enter an amount: "))

balance = balance - amount

#check option is deposit

elif option == 'deposit':

amount = int(input("Enter an amount: "))

balance = balance + amount

else:

print("Invalid transaction.")

#check balance is less than 0 (negative)

if balance < 0:

print("You cannot have a negative balance!")

else:

print("Final balance:",balance)

SCORPION-xisa [38]

Answer:

Option B i.e., mdsswitch# show Vsan membership is the correct option.

Explanation:

The following commands is used by the engineer because it displays the membership of the VSAN( virtual storage area network).

switch# command is used to enter the configuration mode. So, the engineer using the following commands to verify that the interfaces for the research department.

Declare a structure whose tag name is Server and that contains the following fields: manufacturer, a string, model and serialnum

NemiM [27]

Answer:

The answer to this question as follows :

Structure definition:

struct Server //define structure server.

{

string manufacturer;

//define string variable.

string model, serialnum; //define string variable.

int year;

//define integer variable.

double clockSpeed;

//define double variable.

int cores; //define integer variable.

int ram;

//define integer variable.

int storage;

//define integer variable.

};

Explanation:

Structure is a collection of heterogeneous(different type) elements. It is a user-define datatype which is available on the C/C++ programming language. To define any structure we use the struct keyword. The syntax of defining structure can be given as:

Syntax:

struct structure name

{

//define variables

//statements and code.

};

struct structure name

{

//define variables

//statements and code.

}create structure variable;

In the above structure code, we define a structure that is "Server". In this structure, we define different types of variables that is " manufacturer, model, serialnum, year, clockSpeed, cores, ram, and storage". In this structure variable manufacturer, model and serialnum datatype are a string and clockSpeed datatype is double and variable year, cores, ram, and storage data type is an integer.
