A 15-inch candle is lit and burns at a constant rate of 1.6 inches per hour.
1 answer:
Answer:
c = 15: The height of candle is 15 inches when it is not lit.
m = -1.6: The height of candle decreases 1.6 inches for every hour it is lit.
Step-by-step explanation:
We are given the following in the question:
Height of candle = 15 inches
This function gives the length of the candle in inches left after it was burn for t hours.
Comparing the given equation to a linear equation, we have:
where m is the slope and c is the y-intercept.
Comparing we, get
m = -1.6 and c = 15
Interpretation:
c = 15 mean the y-intercept is 15 that is he value of function when t = 0, thus, the height of candle is 15 inches when it is not lit.
m = -1.6 is the rate of change of the function when t increases by 1 unit that is the height of candle decreases 1.6 inches for every hour it is lit.

Hey there! Hello!
For this problem, you first need to figure out how many questions Nicholas got right, got wrong, and didn't answer. Then, you need to compare these to how many points he gets for each one. To do the first thing I mentioned, you need to add together how many problems your question accounts for, then subtract these from 100 and assume that these are questions he got wrong.
So, he has a total of 86 problems correct (times 1 will be 86 points added to his total score), 6 problems unanswered (times 0 will be 0 points that won't affect his score), and 8 problems incorrect (times –1/4, or –0.25, will be 2 points taken away from his total score).
Then, plug them into an equation. Since the unanswered questions don't count for anything, they can be omitted.
Your final answer will be C.
Hope this helped you out! Feel free to ask me any additional questions if you have any. :-)
