Which set of side lengths form a right triangle?

3 ft, 6 ft, 5 ft

10 in., 41 in., 40 in.

15 m, 20 m, 25 m

7 cm, 8 cm, 10 cm

The third option.

Step-by-step explanation:

For a right triangle the square on longest side = sum of the squares on the other 2 sides (Pythagoras's Theorem).

25^2 = 625

15^2 + 20^2 = 625

So its the third set.

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
