Answer:
(a) 
= 
Explanation:
To convert from binary to hexadecimal, convert each 4 binary digits to its hexadecimal equivalent according to the following;
<em>Binary => Hex</em>
0000 => 0
0001 => 1
0010 => 2
0011 => 3
0100 => 4
0101 => 5
0110 => 6
0111 => 7
1000 => 8
1001 => 9
1010 => A
1011 => B
1100 => C
1101 => D
1110 => E
1111 => F
(a) 1100 1111 0101 0111
=> Taking the first four binary digits : 1100
According to the table, the hexadecimal equivalent is C
=> Taking the second four binary digits : 1111
According to the table, the hexadecimal equivalent is F
=> Taking the third four binary digits : 0101
According to the table, the hexadecimal equivalent is 5
=> Taking the last four binary digits : 0111
According to the table, the hexadecimal equivalent is 7
Therefore, the hexadecimal representation of
1100 1111 0101 0111 is CF57
Answer:
Correct Order
2. Select the cell or range you want to move or copy.
1. Move the pointer over the border of the selection until the pointer changes shape.
3. To move the range, click the border and drag the selection to a new location, or to copy the range, hold down the Ctrl key and drag the selection to a new location.
Explanation:
To move or copy range of cells in MS Excel, You first select the cell/range you want to move or copy, hover the mouse pointer and take note when it changes shape, then finally click the border (when you noticed the change of shape of the pointer) and hold down the ctrl key and drag it to the destination location.
<u>Output:</u>
f1 in A
f2 in A
f1 in B
f2 in A
f1 in A
f2 in A
f1 in B
f2 in B
<u>Explanation:</u>
In this snippet, the code makes use of virtual functions. A virtual function is defined as a function that is defined in the base class and redefined in the derived class. If the derived function accesses the virtual function, the program will get executed with the derived class’s version of the function.
In this code, we define the virtual function f1() in class A and also redefine it in class B which is the derived class of A. While executing the program, the function g which takes the object b (class B’s object) as a parameter. It will print class B’s version of f1() rather than class A’s version. This is working off the virtual function.
When you are trying to solve a formula like this one, you need to consider the whole row in the spreadsheet, not just A1 and D1.
So, A1:D1 refers to the whole row, which means that you need to add A1+B1+C1+D1 = 2 + 1 + 5 + 3 = 11.
The answer to the formula according to this spreadsheet is 11.
