Hey, could someone me with this? . a candle burns down at the rate of 0.5 inches per hour. the original height of the candle was 9 inches. part a: write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. for example, the point (0, 9) would represent a height of 9 inches after 0 hours. explain how you obtained the ordered pairs. part b: is this relation a function? justify your answer using the list of ordered pairs you created in part a. part c: if the rate at which the candle burned was 0.45 inches per hour instead of 0.5 inches per hour, would the relation be a function? explain your answer using input and output values.

Part A: 1. (1, 0.5) 2. (2, 1) 3. (3, 1.5) 4. (4, 2) 5. (5, 2.5) 6. (6, 3)

Part B: Yes, this relation is in fact a function.

Part C: No, it would not be a function.

Step-by-step explanation:

Part A: Well, you start at 1 hr. right? yes. So then, at the very beginning at the problem, it says the candle burns at the rate of 0.5 in. per hour. So for 1 hour, the candle will burn .5 inches. At 2 hours, it will burn off 1 whole inch.

Part B:  1 hr. = .5 in. burn,  2 hrs. = 1 in. burns,  3 hrs. = 1.5 in. burns,  4 hrs. = 2 in. burns,  5 hrs.= 2.5 in. burns, 6 hrs. = 3  in. burns.

Part C:  1 hr.= .45 in. burn, 2 hrs. = .9 in burn,  3 hrs. = 1.35 in. burns, 4 hrs. = 1.8 in. burns, 5 hrs. = 2.25 in. burns, 6 hrs. = 2.7 in. burns.    It does not go at a constant rate. The number of inches are all over the place.

Hope this helps you out!! (:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
