Answer:
A
Step-by-step explanation:
Given
3
When the culture was created t = 0, thus
3 = 3 × 1 = 3
That is there were initially 3 bacteria in the culture → A
When it hits the ground, then h=0
find the xintercept or in this case the tintercepts
c=76
v=135
h=-16t^2+135t+76
use quadratic formula
ax^2+bx+c=0
x=
a=-16
b=135
c=76
x=
x=
x=
aprox
x=-0.5297 or 8.967
exclude the negative root since you can't have negative time
means that it takes 8.97 seconds to hit the ground
