A ball is thrown from an initial height of 6 feet with an initial upward velocity of 31 fts. The ball's height h (in feet) after t seconds is given by the following: h=6+311-167
Find all values of t for which the ball's height is 20 feet.
Round your answer(s) to the nearest hundredth.

step-by-step explanation:

hello from mrbilldoesmath!

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.
