Find the perimeter of the triangle defined by the coordinates (9, 0), (-5, 0), and (-10, 6). (Round to nearest tenth)

eduard

The perimeter is 41.7.

We first find the distance between each vertex using the distance formula:
$d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}
\\
\\=\sqrt{(0-0)^2+(-5-9)^2}=\sqrt{0^2+(-14)^2}=\sqrt{196}=14
\\
\\d=\sqrt{(6-0)^2+(-10--5)^2}=\sqrt{6^2+(-5)^2}=\sqrt{36+25}=\sqrt{61}
\\=7.81
\\
\\d=\sqrt{(6-0)^2+(-10-9)^2}=\sqrt{6^2+(-19)^2}=\sqrt{36+361}=\sqrt{397}
\\=19.92$

We now find the perimeter by adding all of the side lengths:
14+7.81+19.92 = 41.73 ≈ 41.7

1) probabillity of getting two red balls in a row is 1/2 (if 80% Bowser is lying)
2) <span>probability of getting 2 red balls in a row is 1/6 (20% Bowser's truth)
3) overall probability </span> $( \frac{4}{5} * \frac{1}{2}) + (\frac{1}{5} * \frac{1}{6}) = \frac{13}{30}$
