Answer:
The answer is below
Step-by-step explanation:
a) The integral  means the total change in level of water in inches from 1 am to 10 am. That is the water level change measured in inches between 1 am and 10 am
 means the total change in level of water in inches from 1 am to 10 am. That is the water level change measured in inches between 1 am and 10 am
b) 7 pm is represented as t = 19 hours, while midnight is represented as t = 24 hours, hence the water level change between 7 pm and midnight is:

c) Using casio calculator to evaluate the integral gives:
 = 2.54 inches
 = 2.54 inches
D) The total daily change in water level =  = 0.35 inches
 = 0.35 inches
 
        
             
        
        
        
Answer:
33.51 in^2
Step-by-step explanation:
Find the area of the circle:
A = πr^2
A = π * 8^2
A = 64π = 201.06 in^2
Find the area of the 60 deg slice:
A * 60/360 = 33.51 in^2

Answer:
6.59 and 3.41
Step-by-step explanation:
To evaluate, substitute n for each of the given values.
So when n= 3:
0.53n + 5 = 1.59 + 5 = 6.59
And when n = -3
0.53 n + 5 = -1.59+5=3.41
