5) A not so agile track star collides with a hurdle with a force of 10,000 N.
The runner who stops in 0.500 seconds upon hitting the hurdle was
traveling with an velocity of 20 m/s. What is her mass? (Show the formula

d.) yes, because the volume of the cone is greater than the volume of the sphere

step-by-step explanation:

answer: the is put the 450

hello from mrbilldoesmath!

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

discussion:

in general, the factorization of a^3 + b^3 is

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

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

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

(a + b) (a^2 - a b + b^2)

a ≈ 172.05
