Determine whether the vectors u and v are parallel, orthogonal, or neither.
Radda [10]
To check if two vectors are orthogonal(perpendicular), simply check their dot product, if their dot product is 0, then they're perpendicular, let's check.

\bf \ \textless \ 7,-4\ \textgreater \ \cdot \ \textless \ -28,16\ \textgreater \ \implies (7\cdot -28)+(-4\cdot 16)\implies -196-64
\\\\\\
\boxed{-264}\impliedby \textit{nope, no orthogonal}

to check if two vectors are parallel, simply check their slope by doing a b/a check, if the slopes are the same, then they're indeed parallel to each other, let's check.

\bf \textit{slope of \underline{u} }\cfrac{7}{-4}\implies \boxed{-\cfrac{7}{4}}\qquad \qquad \textit{slope of \underline{v} }\cfrac{-28}{16}\implies \boxed{-\cfrac{7}{4}}

well, there you have it, the slopes are the same.

Given the preimage and image, find the dilation scale factor​
dimaraw [331]

Answer:

1/2

Step-by-step explanation:

the dilation factor should be 1/2

  1. if u count the dots on the sides of the preimage there are 2 dots that's the length
  2. if u count the dots on the real image it's 4
  3. therefore 2/4 to it's lowest term is 1/2
  4. so 1/2 is the scale factor
