Answer:
 attempts are required to find a matching pair if the digital fingerprint is 64 bits long.
 attempts are required to find a matching pair if the digital fingerprint is 64 bits long.
 attempts are required to find a matching pair if the digital fingerprint is 128 bits long.
 attempts are required to find a matching pair if the digital fingerprint is 128 bits long.
Step-by-step explanation:
Each bit has two options. So
How many attempts are required to find a matching pair if the digital fingerprint is 64 bits long?
So for each of the 64 bits, we have the following number of options.
2 - 2 - 2 - 2 -... - 2
So, in all, there are

options.
So,  attempts are required to find a matching pair if the digital fingerprint is 64 bits long.
 attempts are required to find a matching pair if the digital fingerprint is 64 bits long.
128 bits long?
Using the same logic as the first question.

So,  attempts are required to find a matching pair if the digital fingerprint is 128 bits long.
 attempts are required to find a matching pair if the digital fingerprint is 128 bits long.
 
        
             
        
        
        
Answer:
7 in both boxes
Step-by-step explanation:
In the picture, it shows 
4 (x - 3) = 20
and then it shows
4 (x) - 4 (3) = 20
 so practically you separate the x and 3 and put them in parentheses and then put a 4 next to both of them.
It should be the same as your question.
7 x (8 - 3) 
and then separate 8 and 3 and put a 7 next to both of them.
( 7 x 8) - ( 7 x 3)
Hope it helps and have a great day! =D

The slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept. Since you are given the slope (0.5) and the y-intercept (3), all you have to do is substitute these given values into the equation.  Substituting them in you get: y = 0.5x + 3, which is your answer.
 
        
                    
             
        
        
        
Answer:
 the  radius of the circle is 6cm
Step-by-step explanation:
the area of a circle is given to be  = 36πcm²
radius of the circle = ?
to find the radius of the circle lets start by applying  the formula for finding the area of a circle.
 area of a circle = πr²
36πcm² = πr²
36π = πr²
divide both sides by π
36π/π = πr²/π
36 = r²
to get the value of r we are going to look for a way of getting rid of the square on "r" by squaring 36
r² = 36
r =√36
r = 6cm
therefore the  radius of the circle is 6cm
 
        
             
        
        
        
Answer:
$106.08
Step-by-step explanation:
Given:
6x $5.00
5x $2.00
12x $1.00
9x= 0.50
6x25 cent
42x10 cent
10x5 cent
15=15cent
$97.23
----------------------------------------------------------------------------------
6 five dollar bill is $30.00
so 5 two dollar bill is $10.00
12 one dollar bills is $12.00
9 half dollar bill mean 0.50 cent since it Half and that would make $4.50
6 quarter so 6x25 which equal $1.50
42 dimes and dimes =10 cent so 42x10 which equal $4.20
10 nickels and nickels = 5 cent so 10x5=0.50
15=15 pennies 
-------------------------------------------------------------------------------------
30.00+10.00+12.00+4.50+1.50+4.20+0.50+0.15+97.23 =
