$4m^6 - 16m^{10}$

$= (2m^3)^2 - (4p^5)^2$

$= (2m^3 -4p^5)(2m^3 + 4p^5)$

================================
This expression is the difference of 2 squares :

$\bf 9n^4 - 49n^6$

$= (3n^2)^2 - (7n^4)^2$

$= (3n^2 + 7n^4) (3n^2 - 7n^4)$

after 1 second the ball is 76 feet in the air: after 2 seconds it is 144 feet in the air. Find the height of the function. h(x)=

MArishka [77]

General equation for height, h
h = ut + 0.5gt^2

at t=1s, h = 76 feet
76 = u*1 + 0.5*a*1^2
76 = u + 0.5a

at t=2s, h = 144 feet
144 = u*2 + 0.5*a*2^2
144 = 2u + 2a
72 = u + a

Subtract 2 equations
0.5a = -4
a = -8
u = 80

So the equation,
h(x) = 80t + 0.5*(-8) t^2
h(x) = 80t - 4t^2
