Answer:
A matrix can only be added to (or subtracted from) another matrix if the two matrices have the same dimensions.
Explanation:
Subtracting matrices Similarly, to subtract matrices, we subtract the corresponding entries. For example, let's consider C = [ 2 8 0 9 ] C=\left[\begin{array}{rr}{2} &8 \\ 0 & 9 \end{array}\right] C=[2089] and D = [ 5 6 11 3 ] D=\left[\begin{array}{rr}{5} &6 \\ 11 & 3 \end{array}\right] D=[51163].
Answer:
Grace Hopper.
Explanation:
Grace Hopper was a US Naval Rear Admiral and an American computer scientist who was born on the 9th of December, 1906 in New York city, United States of America. She worked on the first commercial computer known as universal automatic computer (UNIVAC), after the second World War II.
In 1953 at the Remington Rand, Grace Hopper invented the first high-level programming language for UNIVAC 1 by using words and expressions.
Additionally, the high-level programming language known as FLOW-MATIC that she invented in 1953 paved the way for the development of common business-oriented language (COBOL).
Hence, Grace Hopper developed the first compiler and conducted work that led to the development of COBOL.
Answer:
The program to the given statement can be defined as follows:
Program:
//header file
#include <stdio.h> //defining header file
int main() //defining main method
{
int k; //defining integer variable k
for (k=1;k<=97;k++) //defining for loop
{
printf("*"); //print value asterisks
}
return 0;
}
Output:
*************************************************************************************************
Explanation:
Firstly, the headers file is included in the above C-language, and then the main method is described and all computations are performed with this method, which can be described as follows:
- Inside the main method, an integer variable k is declared.
- In the next line, the for loop is declared, which uses the variable k, which starts from 1 and ends when the value of k is less than equal to 97, inside the loop, it will print asterisks.
Answer: Here are some reasons why you might send a professional business letter:
