Answer:
Total temperature change = -32.48 degrees
Step-by-step explanation:
Over 11.2 hours, the temperature changed -2.9 degrees each hour.
Total time elapsed = 11.2 hour.
Temperature change per hour = -2.9 degrees
Total temperature change = Total time elapsed x Temperature change per hour
Total temperature change = 11.2 x -2.9 = -32.48 degrees
So temperature is reduced by 32.48 degrees in 11.2 hours.
Total temperature change = -32.48 degrees
Answer:
.
Step-by-step explanation:
To find
.
First, calculate the corresponding indefinite integral:
Integrate term by term:

Apply the constant rule 

Apply the constant multiple rule 

Apply the power rule 

Therefore,

According to the Fundamental Theorem of Calculus,
, so just evaluate the integral at the endpoints, and that's the answer.
