Answer:
B. 11110111
Explanation:
Binary representation of number 9 = 00001001
Binary representation of -9 would involve calculating the twos complement representation of 00001001
First we compute the ones complement of this number by reversing the bits.
00001001 => 11110110
Next we calculate the twos complement representation by adding 1 to the ones complement.
11110110+1 = 11110111
So the final representation is 11110111.
Answer B (Data storage system)
Answer:
future value = 232369.1361
return % = 384.10 %
Explanation:
given data
principal = $100 per month
time = 40 year = 480 months
rate = 6.25 % yearly = 0.0625 yearly = 0.005208 monthly
to find out
total amount of capital at the end of your investment and percentage is your total return
solution
so here future value formula is
future value = P
..........1
here r is rate and t is time and P is principal
so put all value
future value = 100
future value = 232369.1361
so
Total capital at the end of investment-Total principle invested over the years
232369.1361 - 100 ( 12 × 40 )
184369.1361
so
Return % =
× 100
return % = 384.10 %
