E)

Accepted Answer

To find the value of 11ebfe6a_2cf5_1620_96cc_d9a0fdc3932c_TBX8650_00, we need to look at the second column (X) in the table and find the row where the value is 11ebfe6a_2cf5_1620_96cc_d9a0fdc3932c_TBX8650_00. We can see that this value is in the fourth row. 
To find the corresponding value in the third column (Y) for this row, we need to look at the entry in the third column that has the same value in the first column (Z) as the value in the fourth row of the second column. In this case, the value in the first column for the fourth row is 11ebfe6a_2cf5_1623_96cc_a90f69e19ff5_TBX8650_11, so we need to look for this value in the first column of the third column. We can see that this value is in the eighth row of the third column, and the corresponding value in the fourth column is 11ebfe6a_2cf5_1623_96cc_a90f69e19ff5_TBX8650_11. Therefore, the answer is C.

A) 
B) 
C) 
D)

Accepted Answer

None of the options provide any information about the function or the context in which it is being used. Therefore, the best choice is C, as it is the only option provided that meets the criteria of being a valid answer.

Question 11

Sketch the graph of the function. 
A) 
B) 
C) 
D)

Accepted Answer

The function is periodic with period 4, and it oscillates between y=2 and y=4. The only graph that satisfies these conditions is C. Option A does not oscillate between y=2 and y=4 continuously, option B has the wrong period, and option D does not have a continuous oscillation.

A) 
B) 
C) 
D)

Accepted Answer

The graph is a sine curve with amplitude 2, period 2π/3, and shifted up 1 unit. Option B matches these characteristics. Option A has the correct period and amplitude, but it is shifted down instead of up. Option C has the correct period and shift, but it has an amplitude of 1 instead of 2. Option D has the correct amplitude and shift, but it has a period of 2π instead of 2π/3.

Question 19

Let  . By what value is  increased if  is increased by 1?
A)5.4
B)4.4
C)1
D)42.9
E)38.5

Accepted Answer

In the first section of the code, the portion before the underscore, all numbers and letters remain the same as the code in question. In the second section, the portion between the underscores, the first three characters (2cf) remain the same throughout all three codes. In the third section, the portion between the underscores, the first four characters remain the same (96cc) throughout all three codes. Finally, in the fourth section, the portion after the underscore, the code TBX8650_11 remains the same throughout all three codes.

The only difference between the original code and the second code is in the third section, where one character changes from 0 to 1. Therefore, the value of the code increases by the hexadecimal value of one, which is 4, in the third section.

In the third code, the value of the code changes from 0 to d, indicating an increase of 13 in the hexadecimal system. However, the question asks for the increase if the value in the third section was increased by 1. Therefore, we only need to consider the increase of 1 in the third section, which would result in an increase of 1 in the overall value of the code.

Therefore, the difference between the original code and the third code is an increase of 4.4 (the increase of 4 in the third section and the increase of 0.4 in the last section due to the change in the code). The answer is B.
