Express (76)10 and (-114)10 in 8-bit binary two’s complement arithmetic and then add the numbers. What would be the representati

Pavlova-9 [17]

Answer:

76(10) + (-114)10 = (-38)10

Step-by-step explanation:

To express -114 in two complement

First convert to binary = 0000 0000 0000 0000 0000 0000 0111 0010

Change 1 to 0 and o to 1 = 1111 1111 1111 1111 1111 1111 1000 1101

add 1 to = 1111 1111 1111 1111 1111 1111 1000 1110

(76)10 complement = 0000 0000 0000 0000 0000 0000 0100 1100

Adding the two = 1111 1111 1111 1111 1111 1111 1101 1010 (-38)

0(10) in 16 -bit binary =

05.05)On the coordinate plane below, what is the length of AB?

amm1812

Answer:

Therefore the length of AB is 15 unit.

Step-by-step explanation:

Given:

A ≡ ( -7 , 4 ) ≡ (x₁ , y₁)

B ≡ ( 8 , 4 ) ≡ (x₂ , y₂)

C ≡ ( 8 , -3 )

D ≡ ( -7 , -3 )

To Find:

Length of AB =?

Solution:

Distance Formula between two points is given as

$l(AB) = \sqrt{((x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} )}$

Substituting the values we get

$l(AB) = \sqrt{((8-(-7))^{2}+(4-4)^{2} )}\\l(AB) = \sqrt{((15))^{2}+(0)^{2} )}\\l(AB)=\sqrt{225}=15\ unit$

Therefore the length of AB is 15 unit.
