Ada gets water from the tap that is Forty-eight degrees Fahrenheit. She puts in on the stove to boil for tea. The graph below shows the relationship between time and temperature of the water over the course of 4 minutes. What is the rate of change for this function?
Can you show the graph that they're speaking of?
it wont let me put it
212 - 48 = 164. It is over 4 minutes so the line has a slope or rate of change of 41°F per minute
that answer is not in the chocies
well I don't know what else to do other than subtracting the starting and ending temperatures and then taking that difference and dividing it by the time to get the rate
it goes up 12 degrees every minute
ok
how is it 12 per minute. I took the boiling point of 212 and the starting temp of 48 and subtracted them to get 164. I then divided that by 4 to get 41 per minute so basically what I was doing was this: r = d/t with d being the difference between the starting and ending temperatures
Look at the graph @caters, for each minute the Farenheit goes up 12 degrees 60-48=12 72-60=12 84-72=12 96-84=12
