Answer:
18.37 is the answer so it should be 18.4
Step-by-step explanation:
Answer:
Step-by-step explanation:
Just integrate r(t) with respect to t
Integrate r(t) dt = 400t -(4t^2)/2 + C
= 400t -4t^2 + C
where C is a constant
then replace the above answer with 30 and 0, then do subtraction for both answers
hence the amount of water flows during first 30 mins is
= {400*30 - 4*(30)^2 + C} - {400*0 - 4*(0)^2 + C}
= 12000 - 3600
= 8400 liters
