Answer 1

PLS HELP

A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 6 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, 6) would represent a height of 6 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points)

Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points)

Part C: If the rate at which the candle burnt was 0.3 inches per hour instead of 0.5 inches per hour, will the relation continue to be a function? Explain your answer using input and output values. (3 points)

Answer 2

surely sounds like a "linear function" with initial value (y-intercept) of 6 inches and burn-down rate of -0.5 inch/hour.

Please write out this linear function. Note that it's only good for t=0 or greater.
Choose x (time) values at random and find y for each such x value.

Make your table of x,y pairs.
