His average speed is 2.27 meters per second
With an equation you must isolate x or whatever the variable is. Operations are the things used to make the difference like +,-,x,/.
A great example of this is the following
4x-12=0
First add 12 to both sides making the equation go to
4x=12
now divide 4 from both sides making
x=3
C is the answer hope that helps have a good day
The probability of compound events combines at least two simple events, either the union of two simple events or the intersection of two simple events.
At any time (min), the volume of solution in the tank is
If is the amount of salt in the tank at any time , then the solution has a concentration of .
The net rate of change of the amount of salt in the solution, , is the difference between the amount flowing in and the amount getting pumped out:
Dropping the units and simplifying, we get the linear ODE
Multiplying both sides by allows us to identify the left side as a derivative of a product:
Integrate and divide both sides by to get
The tanks starts off with 30 lb of salt, so and we can solve for to get a particular solution of
