To write the coefficients of the 8 terms, either start with a combination of 7 things taken 0 at a time and continue to 7 things taken 7 at a time or use the 7th row of Pascal’s triangle.
For the first term, write x to the 7th power and 3 to the 0 power. Then decrease the power on x and increase the power on y until you reach x to the 0 and y to the 7.
Simplify by evaluating the coefficients and powers 3

Answer:
The temperature at the start is 35F
The temperature of the room is 74F
<em></em>
Step-by-step explanation:
Given
Solving (a): The temperature at the start.
To do this, we set:
So, we have:
<em>Hence, the temperature at the start is 35F</em>
<em></em>
Solving (b): The room temperature
We have:
To get the temperature of the room, we simply remove the exponential function.
So, we have:
<em>Hence, the temperature of the room is 74F</em>
