Which function below belongs in the same family of functions (has the same parent function) as the given graph?
(hmmm...read each function and decide which one looks the most like the unit we are in...since that's a graph of a rational function)
What type of variation is shown in the following equation? (type: direct, inverse, or joint in the answer box)
If c varies jointly with b and a and c = 20 when b = 2, and a = 4 find a when c = 6 and b = 50.
(enter your answer as a fraction or rounded to the hundreths place)
A lever pivots on a support called a fulcrum. (as shown in the picture)
For a balanced lever, the distance d (in feet) an object is from the fulcrum varies inversely with the object's weight w (in pounds). An object weighing 120 pounds is placed 10 feet from a fulcrum. How far from the fulcrum must a 108 pound object be place to balance the lever?
(round your answer to the nearest tenths place, enter the number only (no units))
The volume (V) of a pyramid varies jointly with its height (h) and base area (A). Write an equation to represent this relationship:
