10) Find the distance between (2, 3) and (-3, -2) A) 2 B) 5 C) 50 = 5 2 D) 25
PSYCHO15rus [73]

Answer:

The answer is

<h2>5 \sqrt{2}  \:  \:  \:  \: units</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

(2, 3) and (-3, -2)

The distance between them is

d =  \sqrt{( {2 + 3})^{2} +  ({3 + 2})^{2}  }  \\  =  \sqrt{ {5}^{2}  +  {5}^{2} }  \\  =  \sqrt{25 + 25}  \\  =  \sqrt{50}  \\  = 5 \sqrt{2}

We have the final answer as

5 \sqrt{2}  \:  \:  \:  \: units

Hope this helps you

In the parallelogram above, BE= 7x-12, CE=10x-5, and DE= 3x+4. What is the length of BD​
kompoz [17]

ABCD is a parallelogram ⇒ BE = DE

So: 7x - 12 = 3x + 4

⇔ 7x - 3x = 4 + 12

⇔ 4x = 16

⇔ x = 16/4 = 4

⇒ BE = 7(4) - 12 = 28 - 12 = 16

⇒ DE = 3(4) + 4 = 12 + 4 = 16

⇒ BD = BE + DE = 16 + 16 = 32

Answer: BD = 32

Ok done. Thank to me :>

14 thanks you so much

Set up the equation 88+7.25h=169. Now that we have the equation and the only variable to solve is h, we will begin the algebra.

1. Using the Subtraction Property of Equality, subtract 88 from both sides to get the equation 7.25h = 81

2. Now use the Division Property of Equality to divide both sides of the equation by 7.25. You should then get h = 11.1724...

Now assuming he is getting paid by the hour, the number of hours he needs to work to get the skateboard is 12.

URGENT PLEASE ANSWER <br> inverse function<br> *see attachment*
Mila [183]

Answer:

Horizontal shift to the RIGHT of <u>one unit</u>

Step-by-step explanation:

When looking at a square root equation, the transformation form is:

f(x) = a\sqrt{b(x-h)} +k

'h' represents a horizontal shift of the graph. Therefore, in this instance:

f(x) = \sqrt{x-1}

This means that there is a horizontal shift to the RIGHT of <u>one unit.</u>
