What terms best describes the set of all points in a plane for which the difference between the distances of a given point to two fixed foci equals a certain constant?
The question asks about the "following". In those circumstances would it be too much to expect that you make sure that there is something that is following?
What is the NAME of the constant k in boyle's law where PV equals k?
Boltzman constant
What is the constant of variation in y equals -4x?
It is -4.
What statement describes the equation y equals 12x?
A function.
The function f n equals n over 45 describes the total distance traveled after n hours at a constant speed of 45 mph Is this true or false?
False. f(n) = n/45 describes how long (in hours) it takes to travel n miles at 45 mph since time = distance ÷ speed. Whereas distance = speed x time which would be f(n) equals n times 45.
Which term best describes the set of all points in a plane for which the sum of the distances to two fixed points equals a certain constant?
Sounds like an elliptical to me.
