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
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:
![\int\limits^{24}_{19 } {W(t)} \, dt\\\\](https://tex.z-dn.net/?f=%5Cint%5Climits%5E%7B24%7D_%7B19%20%7D%20%7BW%28t%29%7D%20%5C%2C%20dt%5C%5C%5C%5C)
c) Using casio calculator to evaluate the integral gives:
= 2.54 inches
D) The total daily change in water level =
= 0.35 inches
Answer:
B). 5.6
Step-by-step explanation:
3.2/x = 4/7
Then, cross-multiply
4x = (3.2) 7
4x = 22.4
x = 5.6
A=3
B=4
C=5
Substitute 3 in for 'a' in the equation, and 5 in for 'c' in the equation to get 17.
