Answer:

Step-by-step explanation:

To obtain vertex form from the given equation use the method of completing the square

given 8y + x² = - y² - 181 + 26x

rearrange having the x terms and y terms together

add y² to both sides

8y + x² + y² = - 181 + 26x ( subtract 26x from both sides )

x² - 26x + y² + 8y = - 181

add (half the coefficient of the x/y terms )² to both sides

x² + 2(- 13)x + 169 +y² + 2(4)y + 16 = - 181 + 169 + 16

completing the square on both the x and y terms

(x - 13)² + (y + 4)² = 4 → D

Find the distance between points p (5, 1) and q (3,4)

DENIUS [597]

Answer:

D=3.60

Step-by-step explanation:

$D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

Where

$(x_1,y_1) = (5,1)$

$(x_2,y_2) = (3,4)$

Replacing these values in the distance formula

$D =\sqrt{(5-3)^2+(1-4)^2}$

$D =\sqrt{(2)^2+(-3)^2}$

$D =\sqrt{4+9}$

$D =\sqrt{13}$

$D= 3.60$
