polygon QRST has vertices Q41/2 , 2 R 8/2 ,2 S 8 1/2 , -3 1/2 and T 4 1/2,-3 1/2 is polygon qrst a reactangle? justify your anwerer

Answers

Answer 1

Answer:

QRST is a rectangle.

Step-by-step explanation:

To decide whether this is a rectangle or not, we have the following options to choose from:

Prove that:

2 pairs of sides are parallel and one angle is 90°

2 pairs of opposite sides are equal and one angle is 90°

1 pair of sides is parallel and equal and one angle is 90°

All four angles are 90°

The diagonals are equal and bisect each other. (same midpoint)

I will go with option 1, because this only requires finding the slope of each of the 4 lines.

Note that:

points Q and R have the same

y

value

horizontal line

points S and T have the same

y

value

horizontal line

points Q and T have the same

x

value

vertical line

points R and S have the same

x

value

vertical line

Therefore QRST has to be a rectangle because horizontal and vertical lines meet at 90°.

The opposite sides are therefore parallel and equal and the angles are 90°

Answer 2

The anwser is that a....

QRST  is a rectangle

Answer:

Hello there, and thank you for posting your question here on brainly.

To convert a decimal to a percent, you have to make the decimal a whole number by getting rid of the decimal point, and then at a % sign.

0.125 ===> 125

125 ===> 125%

Hope this helped!!

125 into a percentage. ... That moves the decimal point up two units, and gives you a percentage. For us, −. 125 becomes −12.5% .

A fish is hovering at –320 feet in relation to sea level. Then it descends 2 feet per second for 8 seconds. Brenda says that the new position of the fish in relation to sea level is represented by the equation below.

2 times 8 + (negative 320) = 336

Which explains whether Brenda is correct?
1. Brenda is correct because her answer represents 336 feet below sea level.
2. Brenda is correct because Negative 16 + (negative 320) = 336.
3. Brenda is not correct because the new position is 2 times 8 + (negative 320) = negative 304.
4. Brenda is not correct because the equation should be Negative 2 times 8 + (negative 320) = negative 336.

Write the equation in function form:
8x + 4y = 20

Answers

Write 8x+4y=20 in function form


Writing a an equation in function form is simply expressing y values in terms of x. In other words when you substitute a particular value for x, you get a particular value for y.

so

8x + 4y = 20

4y = 20 - 8x

y = (20-8x)/4 or y = (20-8x)/4 or y = f(x) = 2(10-4x)/4 = (10-4x)/2 = 5 - 2x = -2x+5

check your answer with a sample values say with a point that solves the equation or a point on the line.....see below....

(2,1)

8(2) + 4(1) = 20......16 + 4 = 20...check.......y=-2(2) + 5 = -4 +5 =1....x=2, y=1...checks....so f(x)=-2x+5

another quick check are the intercepts.....y (x=0)....or x (y=0)

8 (0) + 4 (5) = 20.....(0,5).......y=f(x) = -2 (0) + 5...x = 0..y=5 so again the function checks so

8x + 4y = 20.....is also written as the function y= f(x)= -2x + 5

It took a plane 2 hours to fly from Dallas to New York with the headwind and 1.5 hours to return with the tailwind. If the speed of the wind was 30 mph, how far apart are the two cities?

Answers

Answer:

The distance between the two cities is 360 miles.

Step-by-step explanation:

Let a equal the airspeed of the plane in still air; and d be the distance between the two cities. Then:

d/a+30=1.5

d=1.5a+45

and

d/a-30=2

d=2a-60

So

2a-60=1.5a+45

.5a=105

a=210

d/210-30=2

d=360

The distance between the two cities is 360 miles.
