Question 4

Perform the indicated operations and simplify the expression. ​  ​

Accepted Answer

The question is asking for the sum of hexadecimal numbers. To add hexadecimal numbers, each place value (16^0, 16^1, 16^2, etc.) should be added separately. Starting from the rightmost digits:

1 + 5 = 6 (no carry) 
9 + 2 = B (no carry)
A + F = 19 (carry of 1 to the next place value)
1 + 7 + 1 = 9 (carry of 1 to the next place value)
B + 0 + 0 = B (no carry) 
7 + 3 + E = 18 (carry of 1 to the next place value)
1 + B + F + F = 2B (carry of 1 to the next place value)
1 + C + E = 2B (no carry)

Therefore, the sum is 11eb651f_cbb1_0739_b0a1_911f870ee18a. Choice C matches this result.

Question 11

Perform the indicated operations and simplify the expression. ​  ​

Accepted Answer

To perform the indicated operation, we need to subtract the second hexadecimal number from the third hexadecimal number. This gives us:
B0A1 - 7D4D = 32F4
Replacing this value in the original expression gives us:
11eb651f_cbb1_ca9b_32f4_TB8255_11
Therefore, the correct choice is C.

Question 15

Solve the equation by using the quadratic formula. ​  ​

Accepted Answer

Since we don't have the numbers in the equation, it is easier to use the quadratic formula which is (-b±√b²-4ac)/2a. In this equation, a=11, b=b3, and c=11. Substituting these values in the formula, we get (-b±√b²-4ac)/2a = (-b3±√b3²-4(11)(11))/2(11). Simplifying the equation gives us (-b3±√841)/22. Since the square root of 841 is 29, the equation becomes (-b3±29)/22. Therefore, the answers are (11eb651f_cbb3_506d_b0a1_d37fe34db8e2_TB8255_11 and 11eb651f_cbb3_506e_b0a1_598bdff5f131_TB8255_11).
