Answer:
I believe the answer is B.
Step-by-step explanation:
Because a proportional relationship is one where x is proportional (equal) to y, and Graph A does not fall into that category, and Graph B does, the answer should be B.
Answer:

Step-by-step explanation:

That's about 1,531,000 miles. To calculate it, I took the square root of pi and multiplied that by the diameter of the sun.
Newton's Law of cooling is a differential equation that is simplified by using limits in temperature and time. The simplified equation is:
ln(T-Ts) = ln(T0-Ts) - kt
where
T is the final temperature
T0 is the initial temperature
Ts is the temperature of the surroundings
t is the time
k is a constant
Substituting the values:
ln(T-70) = ln(200-70) - (0.6)(2)
T = 109.16°F
The answer is B.
