A large explosion causes wood and metal debris to rise vertically into the air with an initial velocity of 144 feet per second. The function h ( t ) = 144 t − 16 t 2 gives the height of the falling debris above the ground, in feet, t seconds after the explosion. A) Use the given function to find the height of the debris 2 seconds after the explosion: After 2 seconds, the height is feet.

B) How many seconds after the explosion will the debris hit the ground? seconds.

i got 142 as my answer

step-by-step explanation:

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
