Find the quantity rule before interpreting the requested consequence

A storage tank has capacity 500 L

Time t is measured in min. The model is valid only for 0 ≤ t ≤ 5. Q is the volume in litres, and its signed net rate is in L/min

Q'(t)=4

Q(0)=40

Find the volume at 1 min

Let P(t) be the anti-derivative with zero constant term. The physical quantity will be P(t)+C after applying the supplied value

Enter every coefficient in descending powers, including zero for an absent term

P(t)=A_1t+A_0

\(\text{coefficient of }t\) \(\text{constant coefficient}\)

Find the additive constant C from the supplied quantity value
