H(t) = -16t2 + 186t + 43
at the ground h = 0
hence; -16t2 + 186t + 43 = 0
solving this quadratic equation using the quadratic formula ; a = -16, b = 186, c = 43 ; x = (-b +-(b2 - 4ac)1/2)/2a
gives t = 11.8 seconds to the nearest tenth (note that the negative root has no practical significance)
Answer:
Step-by-step explanation:
V=4/3πr³
v = 1.33*3.142*9³
v = 3046.39in³
New scale = 3046.39*1.5
= 4,569.59in³
