A 15-inch candle is lit and burns at a constant rate of 1.1 inches per hour. Let t represent the number of hours since the candle was lit, and suppose f is a function such that f ( t ) represents the remaining length of the candle (in inches) t hours after it was lit. Write a function formula for f . f ( t )

Respuesta :

Answer: f(t) = 15 - 1.1t

Step-by-step explanation:

Let t represent the number of hours since the candle was lit.

A 15-inch candle is lit and burns at a constant rate of 1.1 inches per hour. This means that in t hours, the candle that would have burnt is 1.1t

The length of the candle that would be left after t hours is expressed as

15 - 1.1t

suppose f is a function such that f(t) represents the remaining length of the candle (in inches) t hours after it was lit, then

f(t) = 15 - 1.1t
