Finding Distance in the Coordinate Plane
GuDViN [60]

The distance between the two points (-1, 4) and (5, 4) is 6 units.

<u>Step-by-step explanation:</u>

The given Coordinate points are (-1, 4) and (5, 4).

The points are considered as (x1,y1) and (x2,y2).

Here,

x1 = -1 and x2 = 5

y1 = 4 and y2 = 4

<u>The distance formula is given by :</u>

Distance = \sqrt{(x2-x1)^2+(y2-y1)^2}

<u>To find the distance between these two points :</u>

The distance formula is used,

Distance = \sqrt{(5+1)^2+(4-4)^2}

⇒ √(6)²

⇒ √36

⇒ 6

Therefore, the between the points is 6 units.

djyliett [7]

Answer: 231

<u>Explanation:</u>

Liwen    Celina

   5x          6x

5x - 21 = (\frac{2}{3})6x

5x - 21 = 4x

<u>-4x +21</u>   <u>-4x +21 </u>

  x        =        21


Liwen: 5x   = 5(21)   = 105

Celina: 6x   = 6(21)   =<u> 126</u>

                       Total:   231

A tree casts a shadow 24 feet long. a 5 foot person casts a 8 foot shadow.How tall is the tree?
ra1l [238]
(length of tree's shadow)/(height of tree) = (length of person's shadow)/(person's height)

24/x = 8/5

24*5 = x*8

120 = 8x

8x = 120

8x/8 = 120/8

x = 15

The tree is 15 feet tall
