Find the distance between (-3,5) and (-6, -4) please help

Kipish [7]

<h3>The distance between Two co-ordinates =</h3>

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

Here,

x1 = - 3

y1 = 5

x2 = - 6

y2 = - 4

Distance =

$= \sqrt{ { ( (- 6 ) - ( - 3))}^{2} + { ( - 4 - 5)}^{2} } \\ = \sqrt{ {( - 3)}^{2} + {( - 9)}^{2} } \\ = \sqrt{9 + 81} \\ = \sqrt{90}$

Hope this will help you....

Put these in order,biggest first 8/100,3/5,7/10

Elodia [21]

Answer:

7/10, 3/5, 8/100

Step-by-step explanation:

First, you try to get all the fractions to the same denominator. If you multiply the numerator and denominator of 3/5 by 20, you’ll get 60/100. If you multiply the numerator and denominator of 7/10 by 10, you’ll get 70/100. Since 8/100 equals .08, it’s obviously the least. 70/100 equals 0.70 and 60/100 equals 0.60, so 7/10 is greater than 3/5.

Find the area of the given quadrilateral.<br> Pls :)

Tasya [4]

I think your teacher may have made a typo. Refer to the diagram below. If we ignore segment ZA for now, we can see a rectangle forms with angle W = angle Y = 90. Also, we can see that WX = 6 is the horizontal base and WZ = 8 is the vertical height.

However, the side opposite WZ (which is XY) should also be 8 cm tall, and not 6 cm. If XY was 6 cm, then point Y would move to where point A is located (and the quadrilateral would be WXAZ instead of WXYZ). This new quadrilateral would not have a 90 degree angle at point Y's new location.

In other words, if we want angle Y to be 90 degrees, then side XY must be 8 units long. I have a feeling this is where the typo is, but your teacher might have been intending to say something else.
