Why

Answers

Well, for the third time in a row Kimberly (Haha jk), let's look at it by decimals. 0=0.00.....1/2=0.50.....1=1.00

0.00009999 would be closeset to 0 because it is the furthest away from the decimal point. The further you move away from the decimal point, the closer you get to zero.

What is the distance between points (10, 7) and (2, 7) on a coordinate plane?

Answers

The distance between points (10, 7) and (2, 7) on a coordinate plane is 8 units.

The given coordinate points are (10, 7) and (2, 7).

What is distance formula?

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x1, y1) and (x2, y2) is Distance = √[(x2-x1)²+(y2-y1)²].

Substitute (x1, y1)=(10, 7) and (x2, y2)=(2, 7) in the distance formula, we get

Distance = √[(2-10)²+(7-7)²]

= √64

= 8 units

Therefore, the distance between points (10, 7) and (2, 7) on a coordinate plane is 8 units.

Hey there, you can solve this using the distance formula!

$Distance = \sqrt{(x_(2)- x_(1))^2+(y_(2)- y_(1))^2}$

Where $x_(1)$ = 10
$x_(2)$ = 2
$y_(1)$ = 7
$y_(2)$ = 7

So...
$Distance = √((2- 10)^2+(7- 7)^2)$
$Distance = √((-8)^2+(0))$
$Distance = √(64)$
Distance = 8 units
