Well you need to know a radius or other information
Answer:
If A(t) represents the amount of salt in the tank at time t, the correct differential equation for A is is dA/dt = 15 - 0.005A
Option C) dA/dt = 15 - 0.005A is the correction Answer
Step-by-step explanation:
Given the data in the question;
If A(t) represents the amount of salt in the tank at time t, the correct differential equation for A is?
dA/dt = rate in - rate out
first we determine the rate in and rate out;
rate in = 3pound/gallon × 5gallons/min = 15 pound/min
rate out = A pounds/1000gallons × 5gallons/min = 5Ag/1000pounds/min
= 0.005A pounds/min
so we substitute
dA/dt = rate in - rate out
dA/dt = 15 - 0.005A
Therefore, If A(t) represents the amount of salt in the tank at time t, the correct differential equation for A is is dA/dt = 15 - 0.005A
Option C) dA/dt = 15 - 0.005A is the correction Answer
If you multiply equation 2 by 3 , you get -6x+3y=24
if we subtract -6x+3y=24 from 2x -3y =12,
we get
2x-3y-(-6x+3y)=12-24
2x-3y+6x-3y=-12
8x-6y=-12,
After this actions we did not remove any variable, but with the elimination method we had to remove one variable, to get equation with another one variable. So 3 is incorrect
