Write a C program to compute Matrix Multiplication of two matrices. Use one dimensional array to store each matrix, where each row is stored after another. Hence, the size of the array will be a product of number of rows times number of columns of that matrix. Get number of row and column from user and use variable length array to initialize the size of the two matrices as well as the resultant matrix. Check whether the two matrices can be multiplied or not. Write a getMatrix() function to generate the array elements randomly. Write a printMatrix() function to print the 1D array elements in 2D Matrix format. Also, write another function product(), which multiplies the two matrices and stores in the resultant matrix. With SEED 5, the following output is generated.

Sample Output

Enter the rows and columns of Matrix A with space in between: 3 5

Enter the rows and columns of Matrix B with space in between: 5 4

Matrix A:

    8     6     4     1     6

    2     9     7     7     5

    1     3     1     1     2

Matrix B:

    9     5     4     5

    9     9     8     1

    4     4     3     5


    2     6     2     1

    4     5     2     4

Product AxB:

168   146   106    91

161   186   125    81

50    52    37    22

In conclusion, the answer is 5x1

What are the approximate solutions of 2x^2 + x = 14, rounded to the nearest hundredth?
Slav-nsk [51]
Hello,

2x²+x-14=0
Δ=1+4*14*2=113

x=(-1-√113)/4=-2,8839...≈-2.88
or x=(-1+√113)/4=2,40753≈2.41

Slove for fg -9h= 10j to get g by itself
Afina-wow [57]
<span>Simplifying fg + -9n = 10j Solving fg + -9n = 10j Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Add '9n' to each side of the equation. fg + -9n + 9n = 10j + 9n Combine like terms: -9n + 9n = 0 fg + 0 = 10j + 9n fg = 10j + 9n Divide each side by 'g'. f = 10g-1j + 9g-1n Simplifying f = 10g-1j + 9g-1n</span>
