Answer:
See solutions for detail.
Step-by-step explanation:
a. 
is the instantaneous rate of change of volume given with respect to time, t.
The volume's rate of change is written as a function of time.
-
is the rate of change in the height of water in the tank with respect to time, t.
b. 
is the only constant. Water flows into the constant at a constant rate, say 
per minute.
c. is positive. Volume water in the take is increasing from time to time.
-The volume at time t=1 is greater than the volume at t=0, hence, it's a positive rate of change.
d. is a positive rate. The initial height of water in the tank is zero.
-The final height at time t is 0.25h. The height is increasing with time.
Hence, it is positive.
Answer:
Choice A.
Step-by-step explanation:
Use graphing calculator
The answer would be 16 3/4 divided by 3 7/8
I think it’s 25%
Because 70 divided by 10 is 7
Which is then 10% so 20% is 14 then 5% is half of 7 which is 3.5
So 70 -7-7-3.5=52.5 which is 25%
Add 2.38 and 4.89 then subtract 3 giving you 4.27
