Question

Write the ordered pair that represents yz. Then find the magnitude of yz . y=14,-23 z=23,-14

Answer 1

Answer:

Ordered pair of yz is ( 9 , 9 ) and Magnitude of yz is 9√2 unit.

Step-by-step explanation:

Given ordered pair of y and z are ( 14 , -23 ) and ( 23 , -14 ) respectively

To find: Ordered pair of yz and magnitude of yz

To find order pair of yz we subtract ordered pair of y from z.

Ordered pair of yz = ( 23 - 14 , -14 - (-23) )

                               = ( 9 , -14 + 23 )

                               = ( 9 , 9 )

Magnitude of yz , $[\left|yz\right|\:=\:\sqrt{9^2+9^2}$

                                    = $\sqrt{81+81}$

                                    = $\sqrt{2\times81}$

                                    = $9\sqrt{2}$

Therefore, Ordered pair of yz is ( 9 , 9 ) and Magnitude of yz is 9√2 unit.
