1) what is the distance between points r and s? round to the nearest hundredth. a) 9.43 b) 13 c) 10.23 d) 80 2) which of these is a pythagorean triple? a) 11,60,61 b) 6,8,15 c) 5,11,12 d)

1)

The formula of a distance between two points:

We have R(2, -2) and S(7, 6). Substitute:

2)

If a, b and c are a Pythagorean triple, then:

for a ≤ b < c.

We have:

A) 11, 60, 61

check:

CORRECT

B) 6, 8, 15 - These are not the sides of the triangle because 6 + 8 = 14 < 15

C) 5, 11, 12

check

INCORRECT
