An object that is projected straight downward with an initial velocity v feet per second travels a distance
s = vt + 16t2 where t = time in seconds. If a coin
dropped from a window 144 feet above the ground has an
initial velocity of O feet per second, in how many seconds
will the coin reach the ground?
O A. 12 seconds
O B. 9 seconds
O c. 4 seconds
O D. 3 seconds

idk

step-by-step explanation:

maybe try   if it is work from a book, if not try

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

step-by-step explanation:

when you realize that you dont know just realize i just took a test and im so smart

zero

step-by-step explanation:

f(2)= x-2

plug in the 2 in the "x"

f(2)=2-2

f(2)=0
