Question

Write the ordered pair that represents y. Then find the magnitude of y.

14-2,5), 2(1, 3)

a. (3. - 2); „13 units

C. (3. - 2); 2-5 units

b. (1,5): V13 units

d. (1,5); 2-7 units

Answer 1

(3,-2),
`√(13) }` units

Explanation:

the correct question is:

Write the ordered pair that represents yz. Then find the magnitude of yz . y(-2,5),z(1,3)

SOLUTION:

points given are y(-2,5) and z(1,3)

`^( \to) _(YZ) = \binom{1}{3} - \binom{ - 2}{5} = \binom{3}{ - 2}`

so, the ordered pair is (3,-2)

next is to find the magnitude:

`|^( \to) _(YZ)| = \sqrt{ {3}^(2) + ( - 2)^(2) }`

`|^( \to) _(YZ)| = √( 9 +4)`

`\\|^( \to) _(YZ)| = √(13) }` units
