matlab code needed. this seems simple but i need help

1. Find the square root of 11. 2. Find the tangent of 65 degrees. 3. Write a matlab command that would create a vector from 0 to 50, with 25 evenly spaced values. Note: while technically correct, you will not receive points by typing every one of the values. 4. The variables X and Y are vectors with similar dimensions. Z is a scalar. Correct the Matlab command line below so that it will work in Matlab: X*Y+Y'Z+X^2 (simply use a comment or disp function to answer this question) Consider the following matrix for questions 5 through 8: 1 92 73 A = 2 85 31 3 57 60 5. Find the standard deviation for each column. 6. Find the standard deviation for each row. 7. Extract all the rows in column 2 from the matrix and define it as the variable B. 8. Extract 85 from the matrix and define it as the variable C. Consider the following vector for questions 9 through 10: B = 45 35 65 50 9. Use a command line to transpose the vector B. 10. Use a command line to find the maximum value of B and its location
