Consider the following code segment. double a = 1.1; double b = 1.2; if ((a + b) * (a - b) != (a * a) - (b * b)) { System.out.println("Mathematical error!"); } Which of the following best describes why the phrase "Mathematical error!" would be printed? (Remember that mathematically (a + b) * (a - b) = a^2 - b^2 .) Responses Precedence rules make the if condition true. Associativity rules make the if condition true. Roundoff error makes the if condition true. Overflow makes the if condition true. A compiler bug or hardware error has occurred.

Step 1
Step 1: The if condition is checking if ((a + b) * (a - b)) is not equal to ((a * a) - (b * b)). Show more…

Let $x$ be a variable of type double that is positive. A program contains the boolean expression (Math.pou $(x, 0.5)=-$ Math. $\operatorname{sqrt}(x)$ ). Even though $x^{1 / 2}$ is mathematically equivalent to $\sqrt{x}$, the above expression returns the value false in a student's program. Which of the following is the most likely reason? (A) Math.pow returns an int, while Math. sqrt returns a double. (B) $x$ was imprecisely calculated in a previous program statement. (C) The computer stores floating-point numbers with 32 -bit words. (D) There is round-off error in calculating the pow and sqrt functions. (E) There is overflow error in calculating the pow function.
Consider the following code segment If $(n !=0 \& \& x / n>100)$ statement 1 else statement2 If $\mathrm{n}$ is of type int and has a value of 0 when the segment is executed, what will happen? (A) An ArithmeticException will be thrown. (B) A syntax error will occur. (C) statement1, but not statement2, will be executed. (D) statement2, but not statement 1 , will be exccuted. (E) Neither statementl nor statement? will be exccuted; control will pass to the first statement following the if statement.
'What happens if the base condition is not defined in recursion ? a. Stack underflow b. Stack Overflow c. None of these d. Both a and b'
