Find the exact distance between (5, 3) and (-2, 8).
Brrunno [24]

Answer:

The answer is

<h2>\sqrt{74}  \:  \:  \:  \: 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

(5, 3) and (-2, 8)

The distance between them is

d =  \sqrt{( {5 + 2})^{2} + ( {3 - 8})^{2}  }  \\  =  \sqrt{ {7}^{2} +  ({ - 5})^{2}  }  \\  =  \sqrt{49 + 25}  \\  =  \sqrt{74}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

We have the final answer as

\sqrt{74}  \:  \:  \:  \: units \\

Hope this helps you

50 POINTS!!!!! HELP Soybean meal is 16% protein; cornmeal is 8% protein.How many pounds of each should be mixed together in orde
tia_tia [17]
The first thing we are going to do for this case is define variables.
 We have then:
 x: Amount of soybean meal
 320 - x: quantity of cornmeal
 We now write the equation that models the problem:
 0.16x + 0.08 (320-x) = 0.09 (320)&#10;
 Rewriting we have:
 0.16x + 25.6 - 0.08x = 28.8&#10;
 From here, we clear x:
 0.16x - 0.08x = 28.8 - 25.6&#10;&#10;0.08x = 3.2&#10;&#10;x = 3.2 / 0.08&#10;&#10;x = 40
 Then, the amount of Soybean meal is:
 x = 40 lb&#10;
 The amount of cornmeal is:
 320 - x = 320 - 40 = 280 lb&#10;
 Answer:
 
cornmeal: 280 lb
 
Soybean: 40 lb.

nadezda [96]

Answer:

(8x-1) (x-1)

Step-by-step explanation:

8x² - 9x + 1

(8x -   ) (x - )

We know it is minus because we have -9x

We have +1 so both have to be -

To fill in the blanks we put 1

The only combination is 1*1 =1

(8x-1) (x-1)

Lets check

8x^2 -x -8x +1

(8x^2 -9x+1
