Suppose that the height (in centimeters) of a candle is a linear function of the amount of time (in hours) it has been burning. after 9 hours of burning, a candle has a height of 24.5 centimeters. after 23 hours of burning, its height is 17.5 centimeters. what is the height of the candle after 21 hours? centimeters

Suppose that the height (in centimeters) of a candle is a linear function of

the amount of time (in hours) it has been burning.

Let x be the amount of time in hours

Let y be the heoght of a candle in centimeters

The two points are then as (9,24.5) and (23,17.5).

Now plug in x=21, we get

Thus the height of the candle after 21 hours is 18.5 centimeters.

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"
