Arocket is launched into the air and follows the path, h (t) = -3 * t^2 + 12 * t t is time measured in seconds. determine how long it takes the rocket to hit the ground. show all work for full credit. my lesson didn't really explain this well for me. either that or i'm not getting it. could someone explain this a bit better? !

check the picture below.

so, the rocket will come back to the ground when h(t) = 0, thus

answ9x x 3=

step-by-step explanation:

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
