Answer:
dQ(t)/dt = 20 - 2Q(t)/5 , Q(0) = 0
Step-by-step explanation:
The mass flow rate dQ(t)/dt = mass flowing in - mass flowing out
Since 5 g/L of salt is pumped in at a rate of 4 L/min, the mass flow in is thus 5 g/L × 4 L/min = 20 g/min.
Let Q(t) be the mass present at any time, t. The concentration at any time ,t is thus Q(t)/volume = Q(t)/10. Since water drains at a rate of 4 L/min, the mass flow out is thus, Q(t)/10 g/L × 4 L/min = 2Q(t)/5 g/min.
So, dQ(t)/dt = mass flowing in - mass flowing out
dQ(t)/dt = 20 g/min - 2Q(t)/5 g/min
Since the salt just begins to be pumped in, the initial mass of salt in the tank is zero. So Q(0) = 0
So, the initial value problem is thus
dQ(t)/dt = 20 - 2Q(t)/5 , Q(0) = 0

i did this question and got it right
Here are the examples of functions in real life.
1. ATM
If you want to withdraw money from your account, the amount of money dispensed by the machine is the amount you request{input}.As a result, the amount requested is a function of the amount distributed{output}. The machine will never give you more or less than what you asked for.
2.Places you can drive with Two Gallons of Fuel
If you still have two gallons of gas in your car's tank, you can visit several locations before running out of gas. As a result, there could be several answers to this question. In this case, the input is two gallons of fuel, and the output is a list of places you can visit with that amount of fuel.
3. Number of Sodas in a Vending Machine
The number of sodas you get from a vending machine is determined by the amount of money you put into it. If you put the same amount in twice and choose the same soda, you will get the same number of cans as you did the first time. In this case, the number is determined by the amount fed into the machine.
