Answer:
B(0) = 0 depth in inches 0 minutes after filling began is 0 ; that is at time = 0 ; depth = 0
B(1) represents the function one minutes after filling began. 
B(9) = 11 depicts that the depth in inches if water 9 minutes after filling began is 11. 
Step-by-step explanation:
The function gives depth of water in inches 7 minutes after filling began 
A.) B(0)=0
The statement B(0) = 0 means the depth in inches 0 minutes after filling began is 0 ; that is at time = 0 ; depth = 0
B.) B(1)
B(1) represents the function one minutes after filling began. 
C.B(9)=11
B(9) = 11 depicts that the depth in inches if water 9 minutes after filling began is 11.

In 12 days, Wendy will do the both again.
Step-by-step explanation:
Given, 
Wendy goes to gym every 4 days 
Wendy swims every 6 days
We will find the least common multiple of both the numbers in order to determine the number of days in which she will do both.
4 = 4,8,12,16,20,....
6 = 6,12,18,24,.....
Therefore; 
The least common multiple of 4 and 6 is 12.
Thus, 
In 12 days, Wendy will do the both again.
