Using Compound interest formula:

The exponential function for calculating the amount of money after t years, A(t), where P is the initial amount or principal, the annual interest rate is r and the number of times interest is compounded per year is n, is given by
 $A(t) = p(1+ \frac{r}{n} )^{nt}$

from the given information:
p = 2,310 , r = 0.035 ,
compounded daily ⇒⇒⇒ n =365
To calculate the time : deposited April 12 and withdrawn July 5
t = 2 months and 23 days = 83 days = 83/365 years
∴ n t = 365 * 83/365 = 83

Amount = 
 $A(t) = 2310(1+ \frac{0.035}{365} )^{83}$ = 2,328.46

The interest earned = 2,328.6458 - 2,310 = 18.46

A tank contains 250 liters of fluid in which 20 grams of salt is dissolved. Brine containing 1 gram of salt per liter is then pu

Vilka [71]

Answer:

$A(t)=250-230e^{-\frac{t}{50} }$

Step-by-step explanation:

A(t) is the amount of salt in the tank at time t.

dA / dt = rate of salt flowing into the tank - rate of salt going out of the tank

dA / dt = (1 g/L)*(5 L/min) - (A(t)/250 g/L) * (5L/min)

dA / dt = 5 g/min - (A(t) / 50) g/min

$\frac{dA}{dt}+\frac{A(t)}{50} = 5\\\\The\ integrating\ factor(IF)= e^{\int\limits \frac{1}{50}dt }=e^{\frac{t}{50} }\\\\Multiplying\ through\ by\ the\ I.F:\\\\\frac{dA}{dt}*e^{\frac{t}{50} }+\frac{A(t)}{50}*e^{\frac{t}{50} } = 5*e^{\frac{t}{50} }\\\\Integrating \ both \ sides:\\\\\int\limits[ \frac{dA}{dt}*e^{\frac{t}{50} }+\frac{A(t)}{50}*e^{\frac{t}{50} }] dt=\int\limits 5e^{\frac{t}{50} } dt\\\\A(t)e^{\frac{t}{50} } =\int\limits 5e^{\frac{t}{50} } dt\\\\$

$A(t)e^{\frac{t}{50} } =250e^{\frac{t}{50} }+C\\\\A(t)=250+Ce^{-\frac{t}{50} }\\\\But\ A(0) = 20\\\\20=250+Ce^{-\frac{0}{50} }\\\\C+250=20\\\\C=-230\\\\A(t)=250-230e^{-\frac{t}{50} }$
