Answer:

The answer is

<h2>12.8 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

B (4, 6) and K (–6, –2)

The distance is

|BK|  =  \sqrt{ ({4 + 6})^{2}  +  ({6 + 2})^{2} }  \\  =  \sqrt{ {10}^{2} +  {8}^{2}  }  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  =  \sqrt{100 + 64}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  =  \sqrt{164}  \\  = 2 \sqrt{41}  \\  = 12.80

We have the final answer as

<h3>12.8 to the nearest tenth</h3>

Hope this helps you

Help me on this problem
Wittaler [7]

Answer:

1 and 3 are both perpendicular to segment NY

Step-by-step explanation:

1. Find the slope of line NY

slope of NY = 5-(-7)/-11-5 = - 3/4

Any line that is perpendicular to NY should have a slope of the inverse of negative slope of NY.

2.Find the slope of perpendicular lines

the inverse of negative slope of NY = - (-4/3) = 4/3

PLEASE HURRY<br><br> 9x^2 + 64 = 0<br><br> I NEED THE WORK SHOWN IN ORDER TO GET CREDIT
seropon [69]

Answer:

x = ± \frac{8}{3} i

Step-by-step explanation:

subtract 64 from both sides

9x² = - 64 ( divide both sides by 9 )

x² = - \frac{64}{9} ( take the square root of both sides )

x = ± \sqrt{-64/9} = ± \frac{8}{3} i

PLEASE HELP MEE!! IVE BEEN DOING THIS ASSIGNMENT FOR OVER 2 HOURS NOW, PLS HELP.. :(
Lesechka [4]

Answer:

x = -3, y = 5

Step-by-step explanation:

first, take the 3x + 17 = y and put it in place for the y in the second equation.

-3x=4x+17+4

then, solve the equation.

-3x=4x+21

-3x-4x=4x-4x+21

-7x=21

-7/-7x=21/-7

x = -3

substitute in other equation

4(-3) + 17 = y

-12 + 17 = y

y = 5

answers are x = -3 and y = 5

Find a cubic polynomial with integer coefficients that has $\sqrt[3]{2} + \sqrt[3]{4}$ as a root.
Paul [167]

Find the powers a=\sqrt{2}+\sqrt{3}

$a^{2}=5+2 \sqrt{6}$

$a^{3}=11 \sqrt{2}+9 \sqrt{3}$

The cubic term gives us a clue, we can use a linear combination to eliminate the root 3 term $a^{3}-9 a=2 \sqrt{2}$ Square $\left(a^{3}-9 a\right)^{2}=8$ which gives one solution. Expand we have $a^{6}-18 a^{4}-81 a^{2}=8$ Hence the polynomial $x^{6}-18 x^{4}-81 x^{2}-8$ will have a as a solution.

Note this is not the simplest solution as $x^{6}-18 x^{4}-81 x^{2}-8=\left(x^{2}-8\right)\left(x^{4}-10 x^{2}+1\right)$

so fits with the other answers.
