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

The formula for the volume of w sphere is v=4\3 r3 what is the formula solved for r?
Lyrx [107]
V of w sphere = \frac{4}{3}\pir³
Multiply by 3 on either sides to get rid of the fraction.
V * 3 =  \frac{4}{3} *3 \pi r^3
3V = 4\pir³
Now divide either sides by 4\pi to isolate r³
\frac{3V}{4 \pi } =  \frac{4 \pi }{4 \pi }r³
4\pi and 4\pi cancels out
\frac{3V}{4 \pi } = r³
Take the cube root to isolate r.
\sqrt[3]{ \frac{3V}{4 \pi } } =  \sqrt[3]{r^3}
the cube root cancels the cube

\sqrt[3]{ \frac{3V}{4 \pi } } = r

Help me please thank you.

The correct answer is A: 2.

The slope compares the vertical change (the rise) to the horizontal change (the run) when moving from one fixed point to another along the line.

If you look at your graph, it takes 2 units up and 1 unit to the right in order to get to the next point on the line.

Therefore, the slope of the line is 2/1, or simply 2. It has a positive value because the line is sloping upward.

If $15,000 is invested at an interest rate of 2% per year, compounded semiannually, find the value of the investment after the g
Gennadij [26K]

Answer:

Step-by-step explanation:

If $10,000 is invested at an interest rate of 2% per year, compounded semiannually, find the value of the investment after the given number of years. (Round your answers to the nearest cent.)

a)6 years

b)12 years

c)18 years

***

compound interest formula: A=P(1+r/n)^nt, P=initial investment, r=interest rate, n=number of compounding periods per year, A=amt after t-years.

For given problem:

P=10000

r=.02

n=2

t=6, 12, 18

..

A(6)=10000(1+.02/2)^2*6

A(6)=10000(1.01)^12=11,268.25

A(12)=10000(1.01)^24=12,697.35

A(18)=10000(1.01)^36=14,307.69
