Find the distance between the points (0,0) and(6,-8)

Y_Kistochka [10]

The formula of a distance between two points:

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

We have the points (0, 0) and (6, -8). Substitute:

$d=\sqrt{(6-0)^2+(-8-0)^2}=\sqrt{6^2+(-8)^2}=\sqrt{36+64}=\sqrt{100}=\boxed{10}$

T= 1,-1 u= 2, -4

Monica [59]

Answer: 3.16 units (Option C)

Step-by-step explanation:

The key to this problem is to use the distance formula, which is:

Distance = $\sqrt{(x₁-x₂)²+(y₁-y₂)²}$

The first point, T = (x₁,y₁), and the second point, U = (x₂,y₂).

Plugging the two points into the equation, we get:

Distance = $\sqrt{(1-2)^{2}+(-1-(-4))^{2} }$

The values within the parenthesis are subtracted:

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

The values are then squared:

Distance = $\sqrt{1+9}$

Finally, they are added together:

Distance = $\sqrt{10}$

$\sqrt{10}$ can be approximated as 3.16, so the distance between the two points is 3.16 units.
