Find the distance between each set of points. Round to the nearest tenth, when necessary. (-3, 2) and (1, -6)

vovangra [49]

Answer:

<h2>The answer is 8.9 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

(-3, 2) and (1, -6)

The distance between them is

$d = \sqrt{ ({ - 3 - 1})^{2} + ({2 + 6})^{2} } \\ = \sqrt{ ({ - 4})^{2} + {8}^{2} } \\ = \sqrt{16 + 64} \\ = \sqrt{80} \: \: \: \: \: \: \: \: \: \: \\ = 4 \sqrt{5} \: \: \: \: \: \: \: \: \: \: \\ = 8.9442719...$

We have the final answer as

8.9 units to the nearest tenth

Rachel earned \$34$34 in 44 hours at her job today. She wants to know how much she could earn (e)(e) tomorrow if she works 1010

kari74 [83]

Answer:

<em>Rachel will earn $85 in 10 hours.</em>

Step-by-step explanation:

Rachel earned $34 in 4 hours at her job today.

Suppose, she will earn $x$ dollar in 10 hours tomorrow.

So, <u>according to ratio of 'dollar' and 'hours'</u>, the equation will be.....

$\frac{34}{4}=\frac{x}{10}$

After cross multiplying, we will get.....

$4x= 34*10\\ \\ 4x= 340\\ \\ x=\frac{340}{4}=85$

Thus, Rachel will earn $85 in 10 hours.
