Answer:
Here, James took the right decision. I will clarify this with few points.
1st - If he purchases a car at high interest rate, he will still have all his debt on previous credit card standing as it is. He will have to pay car loan plus his older dues thus paying at double places.
2nd - It is likely that he can still default on loans as paying double money each month can create problems and James can again stop making payments.
3rd - If James starts paying his debts now, he can be free in a few years time and his credit score will again become good. Then he will get the regular rate of interest for his car as he will be debt free.
So, we can say, he made the right decision.
Answer:
30.06 degree Celsius at 4:00 PM.
Step-by-step explanation:
We have been given that on a hot Saturday morning while people are working inside, the air conditioner keeps the temperature inside the building at 24 degrees C. At noon the air conditioner is turned off, and the people go home. The temperature outside is a constant 35 degrees C for the rest of the afternoon. The time constant for the building is 5 hr. We are asked to find the temperature inside the building at 4:00 PM.
We will use Newton's law of cooling to solve our given problem.
, where
= Temperature after t hours.
= Temperature of surrounding environment,
= Time constant.

Upon substituting our given values in Newton's cooling law, we will get:


To find the temperature at 4:00 pm, we will substitute
in our formula as:






Therefore, the temperature inside building would be approximately 30.06 degree Celsius at 4:00 PM.
