Which expression gives the distance between the points
(1,-2) and (2,4)?​

Answers

Answer:

(1, 6)

Explanation:

To find the distance between the two points, we would have to find the distance in the x and y values.

The x value in both equations is 2 and 1.  To find the distance between these points we would just need to subtract 2-1 which equals 1.

The y value in both equations is -2 and 4. Since one of the numbers is in the negatives, we would have to imagine a graph. If our point is on -2, we would have to count up the marks until we got to four. So, 2+4=6.

Note- this isn't how adding negative and positive numbers work but when it comes to graphs this is how it works. :p

So, your distance between the points is (1,6)

How have new technologies helped scientists determine the age of Earth?

Answers

Answer:

Radioisotopic dating as a new technology has really helped to determine the age of the earth.

Explanation:

The actual age of the earth has been a subject of wanton speculation among different groups of people. Speculations arise from religious, cultural and philosophical perspectives.

However, studies using many radioactive isotopes believed to be present from the origin of the Earth and having extremely long half lives have been most helpful in determining the age of the earth. Radioisotopic dating is a common technique used to determine the age of ancient artifacts. It has shed a great light on the possible age of the earth.

Hence the application of radioisotopic dating as a new technology has really helped to determine the age of the earth.

Find the DISTANCES of AB and CD to determine if AB is congruent to CD. A(-7,1) B(-4,-3) C(3,-5) D(7,-2)

Answers

Answer:

AB is congruent to CD

Explanation:

Given the following :

A(-7,1) B(-4,-3) C(3,-5) D(7,-2)

Distance AB:

A(-7,1) ; B(-4,-3) ;

AB = √[(X2 - x1)^2 + (y2 - y1)^2]

AB = √[(-4 - (-7))^2 + (-3 - 1)^2]

AB = √[(-4 + 7)^2 + (-3 - 1)^2]

AB = √[(3)^2 + (-4)^2]

AB = √(9 + 16)

AB = √25

AB = 5

C(3,-5) D(7,-2)

Distance CD ; x1 = 3, y1 = - 5, x2 = 7, y2 = - 2

CD = √[(X2 - x1)^2 + (y2 - y1)^2]

CD = √[(7 - 3)^2 + (-2 - (-5))^2]

CD = √[( 4 )^2 + (-2 + 5)^2]

CD = √[(4)^2 + (3)^2]

CD = √(16 + 9)

CD = √25

CD = 5

CD = AB, Hence, AB is Congruent to CD
