Using the Distance Formula, find the distance between points (-1, -7) and (-3,-5) to the nearest tenth.
MrMuchimi

Answer:

The answer is

<h2>2.8</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

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

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-1, -7) and (-3,-5)

The distance between them is

d =  \sqrt{ ({ - 1 + 3})^{2}  +  ({ - 7 + 5})^{2} }  \\  =  \sqrt{ {  2}^{2}  + ( { - 2})^{2} }  \\  =  \sqrt{4 + 4}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \\  =  \sqrt{8}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\   = 2 \sqrt{2}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \\  = 2.8284271247

We have the final answer as

<h3>2.8 units to the nearest tenth</h3>

Hope this helps you

What is the value of the missing angle (x+15)
Luden [163]

Answer:

x = 70

Step-by-step explanation:

The total interior angle in a square, even with not a perfect square, adds to 360

Set your formula up as

360 = (x+15) + x + 115 + 90

360 - 115 - 90 - 15 = 2x

140 = 2x

140/2 = x

70 = x
