A tank with a capacity of 100 gallons initially contains 50 gallons of water with 10 pounds of salt in solution. fresh water ent

steposvetlana [31]

Let $A(t)$ be the amount of salt (in pounds) in the tank at time $t$ . We're given that $A(0)=10\text{ lb}$ .

The rate at which the amount of salt in the tank changes is given by the ODE

$A'(t)=\dfrac{2\text{ gal}}{1\text{ min}}\cdot\dfrac{0\text{ lb}}{1\text{ gal}}-\dfrac{1\text{ gal}}{1\text{ min}}\cdot\dfrac{A(t)\text{ lb}}{50+(2-1)t\text{ gal}}$

$A'(t)+\dfrac{A(t)}{50+t}=0$

$(50+t)A'(t)+A(t)=0$

$\bigg((50+t)A(t)\bigg)'=0$

$(50+t)A(t)=C$

$A(t)=\dfrac C{50+t}$

Given that $A(0)=10$ , we find that

$10=\dfrac C{50+0}\implies C=500$

so that the amount of salt in the tank is described by

$A(t)=\dfrac{500}{50+t}$

The tank will be filled when $50+t=100$ , or after $t=50$ minutes. At this time, the amount of salt in the tank is

$A(50)=\dfrac{500}{50+50}=5\text{ lb}$

If a high school football team looses 7 yards on 2 consecutive days, then has gained of 3 yards, how far will the ball be from t

nika2105 [10]

Answer: 11 yards

Step by step: multiple 7 by 2 because you lost 7 yards in 2 days. You would get 14 yards back from the starting line of scrimmage, but you still need to add the 3 yards they gained leaving you with 11.
