An optimal solution to a linear programming problem MUST lie A. somewere on the line between two corner points. B. somewhere out

g100num [7]

Answer:

D. at the intersection of at least two constraints.

Explanation:

Linear programming is an optimization technique which is fine for the purpose of getting the best solution such as maximizing profit or certain o 4th era quantities. It is fine by modelling real life problems into mathematical models that have linear relationships or constraints such as in the form of objective functions. In linear programming, an objective function defines the formula for quantity optimization and the goal from this is to determine variable values that maximize or minimize the objective function depending on the problem robbery solved.

Create a file account.cpp containing a Bank Account Class.

Daniel [21]

Answer:

#include <iostream>

using namespace std;

class BankAccount {

string name = name;

double balance = balance;

BankAccount( string name, double balance ) {

string name = name;

double balance = balance;

return 0;

}

string getName( ){

return name;

}

double getbalance( ) {

return balance;

void setName( string username){

name = username;

}

void setbalance( double newBalance){

balance = newBalance;

}

int main( ) {

BankAccount user1(John, 0.0);

BankAccount user2(Jane, 0.0);

user1.setbalance( 2300.00)

user2.setbalance( 4300.00)

cout << user1.getname() << user1.getbalance();

}

Explanation:

The C source code above using a class to create a data structure of a bank account user name and balance. The attribute name and balance are private to the class and can be retrieved and modified through the get and set methods.

Consider the code below. Note that the catch statements in the code are not implemented, but you will not need those details. As

Missing Part of Question

An exception raised by the instruction in i3 would be caught by the catch statement labeled?

Answer:

e3 and e4.

Explanation:

The instruction tag i3 points to the following code segment

a[++i] = (double) (1 / x); // i3

The code segment above performs arithmetic operation (double)(1/x)

And then assigns the value of the arithmetic operations to an array element a[++I]

It's possible to have one or both of the following two exceptions.

1. Error in Arithmetic Operation

2. Index of Array out of bound

These are both represented in exception tags e3 and e4

catch (ArithmeticException ex) {...} // e3

catch (ArrayIndexOutOfBounds ex) {...} // e4

Exception e3 can arise when the program try to carry out invalid arithmetic operation.

For instance, 1/0 or 0/0.

This will lead to ArithmeticException to be thrown

Exception e4 can arise when the program tries to assign values to an index that's not in an array.

Say, the total index in a given array a is 5.

The index of this array is 0 to 4; i.e. a[0] to a[4]

The moment the program tries to assign values to array element other than the ones I listed above (e.g a[5]) ArrayIndexOutOfBounds exception will be thrown

Which of the following savings vehicles usually requires a high minimum balance

GuDViN [60]

A Savings Vehicle is an effective way to hold your savings. It could be a savings account. But some requires a high minimum balance such as Certificate of Deposit (CD). It is generally issued by commercial banks. It is a time deposit too and restricts you from withdrawing funds.
