What is the length of segment TR with T(-4,5) and R(2, -1)

Brilliant_brown [7]

Answer:

The length of segment TR with T(-4,5) and R(2, -1) is 8.49

Step-by-step explanation:

We need to find the length of segment TR with T(-4,5) and R(2, -1)

The length of segment can be found using distance formula.

The distance formula is: $Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Putting values and finding length

We have: $x_1=-4, y_1=5, x_2=2, y_2=-1$

$Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Distance = \sqrt{(2-(-4))^2+(-1-5)^2}\\Distance = \sqrt{(2+4)^2+(-1-5)^2}\\Distance = \sqrt{(6)^2+(-6)^2}\\Distance = \sqrt{36+36}\\Distance = \sqrt{72}\\Distance=8.49$

We found Distance = 8.49

So, The length of segment TR with T(-4,5) and R(2, -1) is 8.49.

How to solve the above simultaneous equation?

soldier1979 [14.2K]

Answer:

C -2 or 1

Step-by-step explanation:

So from the equation you have x^2-x-1=-2*x+1

x^2-x-1+2*x-1=0

x^2 +x -2 =0

D= 1^2 -4*(-2)= 1+8=9

x = (-1+-3)/2

So x is either (-1+3)/2=2/2=1

or (-1-3)/2=-2

erastova [34]

Answer:

Circumference of the circle drawn by Ginna is twice the Circumference of the circle drawn by Pierce.

Step-by-step explanation:

Given:

Radius of the circle drawn by Pierce = 3 cm

We need to find circumference of gianna's circle compare with the circumference of Pierce's circle.

Solution:

Radius of the circle drawn by Pierce = 3 cm

so we will find the Circumference of circle drawn by Pierce.

Now we know that;

Circumference of the circle is given by 2 times π times radius of the circle.

framing in equation form we get;

Circumference of the circle drawn by Pierce = $2\pi\times 3=6\pi\ cm$

Now Given:

Ginna draws a circle with a radius that is twice as long as the radius of pierce's circle.

So we can say that;

radius of the circle drawn by Ginna is equal to 2 times radius of circle drawn.

so we can say that;

radius of the circle drawn by Ginna = $2\times3 = 6\ cm$

Circumference of the circle drawn by Ginna = $2\pi\times 6=12\pi\ cm$

Now we can see that;

Circumference of the circle drawn by Ginna is $12\pi \ cm$ while Circumference of the circle drawn by Pierce is $6\pi \ cm$

So we can say that;

Circumference of the circle drawn by Ginna is twice the Circumference of the circle drawn by Pierce.
