Zulu 6. radius of the moon 7. Jan_Hus Are the following valid statements for Matlab, if you are given the following variables: a = 6, b = 4, c = [2 34: 1 2 3], d= [2;3], e = {c, d, a, 'Professor'}? If it is a valid statement, then solve it and provide the answer which would display(don't worry about how it would display, just the value, matrix or string, etc.), if it is not valid write "not valid". 8. y =a + b 9. z + a = b 10. % z +a = b 11. area = pi(r^2) 12. area=pi(a^2) 13. e(1, 3) 15. e(1, 4)/d What is the result of the following Matlab commands (16 and 17)? 16. x = 3 Y=4 q = x*Y/x + y Z = [x, Y, q] 17. a = {14: 6: 'Carlos'} a{1, 1} = 8
