2. A person just purchased a vending machine with three compartments. Each compartment has the
dimensions of 6 inches by 8 inches by 18 inches,
Assuming the vending machine uses gumballs that
are approximately spherical and 2 inches in diameter,
how many gurnballs should fit in one of the
compartments?
(Hint: Packing spheres in a rectangular prism usually
take up 190% of the volume of spheres.)

108 is the answe

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
