The function h(t)=-4.9t^2+s_0 represents the approximate height (in meters) of a falling object t seconds after it is dropping from an initial height s_0 (in meters). A can is dropped from an initial height of 44.1 meters. a. After how many seconds does the can hit ground?

b. Suppose the initial height is m meters lower. How will this affect part (a)?

Think What strategies and tools will you use to solve the problem?

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.
