Given quadrilateral RSTU, determine if each pair of sides (if any) are parallel and which are perpendicular for the coordinates

nika2105 [10]

We would need to figure out the gradient of each "pair", as provided in the image.

The equation of the gradient is found by,

m = $\frac{ y_{2 } - y_{1 } }{ x_{2 } - x_{1 } }$

Parallel lines mean they have the same gradient
Perpendicular lines will follow the formula $m_{1 } * m_{2 } = -1$
"None" will apply to those that do not follow either.

Now we calculate the gradient of the pairs given to us by substituting the x and y values.

RS = $\frac{2-5}{8-(-1) }$
= $-\frac{1}{3}$

TU = $\frac{-2 - 5}{-4 -5}$
= $\frac{7}{9}$

Therefore, the "pair" RS and TU will be NONE.

ST = $\frac{5 - 2}{5-8}$
= -1

RU = $\frac{-2 -5}{-4 -(-1) }$
= $\frac{7}{3}$

Therefore, the "pair" ST and RU is also NONE.

Hope this helped! Feel free to ask me if there's any part of the working you don't understand :)

Answer:

X : Z = 6 : 5

Step-by-step explanation:

X : Y = 3 : 1

Double both sides

X : Y = 6 : 2

Y : Z= 2 : 5

Combined

X : Y : Z = 6 : 2 : 5

Therefor

X : Z = 6 : 5

You have probably heard of Albert Einstein's famous formula: E = mc2. While this is an important formula that you may use at som

Gre4nikov [31]

D = S x T (Distance = Speed x Time)
S = D / T
T = D / S

When I need to drive to a neighboring state for my job, I look on maps
and find out how far away my destination is, and then use this formula
to calculate how long it will take me to get there, how fast I need to drive
in order to get there in the amount of time I have, how far I can get in the
time I have if I drive only at safe and legal speed, and what time I need to
head back in order to get home in time for dinner..

F = 1.8C + 32
C = 0.55 (F - 32)

These are the formulas to convert between Fahrenheit and Celsius expressions
of temperature. I use them when I'm discussing the weather with my daughter
in Israel, or with my customers almost anywhere outside the USA.

F = M x G
Weight = Mass x Gravity

This formula deals with the relationship between mass and weight. It's
used when you need to calculate the weight of some particular mass on
some particular planet. I use it almost every day, when I'm answering
questions in the Physics department on Brainly, and trying to explain
my answers.
