The total water pumped out is equal to 210 multiplied by 3 which equals to 630 gallons.
This gives the volume of the tank 3 days ago as 630 + 6600 = 7230 gallons
Answer:
See below
Step-by-step explanation:
I will describe this set in R³. Let P=(x,y,z) be a point equidistant to A and B, that is, the distance from P to A is equal to the distance from P to B.
First, using the usual distance formula, the distance from P to A is equal to 
On the other hand, the distance form P to B is equal to 
P is equidistant from A and B if and only if P satisfies the equation d(P,A)=d(P,B), that is,

Take the square in both sides of this equation to get


You can simplify using difference of squares and multiplying like this:


which is the equation of a plane.
