  x = 25√2

Step-by-step explanation:

The Pythagorean theorem is used to relate the sides of a right triangle to the hypotenuse. The sides are marked as being the same length, so both are x. Then we have ...

  50² = x² + x²

  50² = 2x² . . . . . . . . collect terms

  2·(2500/4) = x² . . . . . multiply by 2/4*

  √(2·625) = x . . . take the square root

  25√2 = x

* We use a version of 1/2 that has a prefect square in the denominator (2/4) so that we don't end up with an irrational denominator when we take the square root. It's a little bit of planning ahead.

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
