Y*x^2=k
y=3, x=18 ⇒ 3*18^2=3*324=972=k
x=3, 972=y*x^2=y*9
y=972/9
y=108

Find the distance between (1, 3) and (-2, -6) and put it in simplest radical form

GarryVolchara [31]

Answer:

$\tt 9.48$

Step-by-step explanation:

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

$\tt Distance= \sqrt{(-6-3)^2+(-2-1)^2}$

$\tt =\sqrt{9^2+3^2}$

$\tt =\sqrt{81+9} =\sqrt{90}$

$\tt Distance=\sqrt{90} =9.48$
