How do I answer these questions?

1.2.6 Explain how to use quadratic.py (PROGRAM 1.2.4) to find the square root of a number 1.2.7 What does stdio.writeln ((1.0+23 4) /4) write? 1.2.8 Suppose that a is 3.14159. What do each of these statements write? a. stdio.writeln(a) b. stdio.writeln(a 1.0) c. stdio.writeln(8// int(a)) d. stdio.writeln(8.0 a) e. stdio.writeln(int (8.0 a)) Explain each outcome. 1.2.9 Describe the effect of writing sqrt instead of math. sqrt in PROGRAM 1.2.4. 1.2.10 Does (math.sqrt (2) * math.sqrt(2)2) evaluate to True or False? 1.2.11 Compose a program that takes two positive integers as command-line ar- guments and writes True if either evenly divides the other. 1.2.12 Compose a program that takes three positive integers as command-line arguments and writes False if any one of them is greater than or equal to the sum of the other two and True otherwise. (Note: This computation tests whether the three numbers could be the lengths of the sides of some triangle.) 1.2.13 Give the value of a after the execution of each of the following sequences: a True a-not a a not a a not a a=2 a=a*a a a +a a=a+a a a* a 1.2.14 A physics student gets unexpected results when using the code force G massi mass2/ radius radius
