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
Answer:
5
Step-by-step explanation:
If 3.5 cups of flour makes 7 servings, then 0.5 cups of flour are needed for each serving if you divide 3.5 by 7, 10 times 0.5 is equal to 5.

1) Each two revolutions gets us 16 feet, so the answer is
Answer: 8 feet per revolution
2) What's the slope?
The rate, the distance per revolution, <em>is </em>the slope of distance versus revolutions.
Answer: 8
