Answer: Celsius scale
Step-by-step explanation:
Fahrenheit scale is established from the freezing and boiling temperatures of water, which are:
Freezing temperature of water:
Boiling temperature of water: 
Which means that all temperatures below
are below the freezing temperature of water. Therefore, if Jen is in the Summer season, which is characterized by high temperatures, it is incoherent to think that the thermometer is using the Farenheit scale.
Now,
is in accordance with the high temperatures recorded in the summer season.
If we want to know how much
is in Farenheits, we must use the following conversion formula:

Answer:
x=−0.433107,3.352224
Rounding up should be -0.4 and 3.4
Step-by-step explanation:
Answer:
1.4
Step-by-step explanation:
The average rate of change is the "rise" divided by the "run".
rise/run = (f(4) -f(-1))/(4 -(-1)) = (0 -(-7))/(4+1)
rise/run = 7/5 = 1.4
The average rate of change on the interval [-1. 4] is 1.4.
Answer:
2 miles
Step-by-step explanation:
10.2 (total amount of miles ran) - 2.2(fifth day) = 8m
8=miles ran in total for the first 4 days
8 miles / 4 days = 2 miles per day for the first 4 days
