Answer:

S=(-2, -9)

T=(-8, -9)

U=(-9, -5)

V=(-6, -5)

Step-by-step explanation:

rotating counter clockwise 90 degrees has a simple formula: (-y, x) simply take your ordered pair and rearrange it to match this formula.

ex. (3, 4) would become (-4, 3)

(-y, x) the negative symbol in front of the y means to switch the sign from either positive or negative to its opposite. since there is no symbol in front of the x you keep that numbers sign the same.

Find the length of the line segment displayed below. Round your answer to the nearest hundredth (2 decimal places)
svlad2 [7]

Answer:

AB=5.83

Step-by-step explanation:

Distance Formula=

\sqrt{(x2 - x1)^{2}  - (y2 - y1)^{2} }

Plugging our values in, we get:

\sqrt{(7 - 2)^{2} + (4 - 1)^{2}  }

And if we solve it like this:

\sqrt{25 + 9}

We end up with:

\sqrt{34}

Which is about 5.83
