The vertices of square RSTV have coordinates R(-1,5), S(-3,1), T(-7,3), and V(-5,7). What is the perimeter of RSTV?
kompoz [17]

The perimeter of square RSTV is: 17.88 units

Further explanation:

As the given figure is a square, all of its sides will be equal. So we have to find one side to find the perimeter.

Given

R(-1,5), S(-3,1), T(-7,3), and V(-5,7)

The distance formula will be used to find the side

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^@}

Let x be one side of square

RS=x=\sqrt{(-3-(-1))^2+(1-5)^2}\\=\sqrt{-3+1)^2+(-4)^2}\\=\sqrt(-2)^2+(-4)^2}\\=\sqrt{4+16}\\=\sqrt{20}\\=4.47

Let P be the perimeter of square

P= 4x

P=4*4.47

=17.88 units

The perimeter of square RSTV is: 17.88 units

Which of the following will be equal to 1⁄4?
docker41 [41]

Answer:

C - 100% of 0.25

Step-by-step explanation:

This answer is basically the same as 25% of 100, just worded differently to confuse you.

25 is 1/4th of 100, so this should be the answer. :)

If you're curious of what the other answers amount to:

One hundredth of 250 = 2.5

50% of 5 = 2.5

40% of 1 = 0.4

Answer choice A

Step-by-step explanation:

Use the slope intercept form y = mx + b to find the slope m and y-intercept b.

Slope = 4/3

y intercept = (0,-3)

Therefore the answer choice is A, 4/3 ; -3
