Answer:
You have 44$, your brother has 11$.
Step-by-step explanation:
Let  be the amount of money your brother has.
 be the amount of money your brother has.
Since you have four times the amount of money your brother has, we can call the amount of money you have  .
.

Thus, you have:

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.
