What about these two?


12. The temperature was 56 degrees this morning but dropped one degree per hour through the rest of the day. Use the graph you made for the equation for this problem, to approximate the answer to the following question: What temperature was it 15 hours later, according to your graph?

13. The temperature was 56 degrees this morning, but dropped one degree per hour through the rest of the day. Read over the problem and look at the graph you made to decide how to answer this question. Would it make sense to predict the temperature in 45 hours? Why or why not?

anonymous · Answer

the equation for this problem is t = 56 - h

where t = time and h = hours

so temperature after 15 hours = 56 - 15 = 41 degrees.

The graph would be a straight line starting at 56 on t axis and the downward slope would have agradient of -1.

tp the second questions - the answer is it would not make sense because you are going into another day and the temperature is very unlikely to fall at same rate during that time  - it would fall during the night that start rising through the daylight.

anonymous · Answer

Yeah, I don't get it.

what dont u get exactly? how i got t = 56 - h?
