Answer:
B there were 4 ducks living in Anoops pond when he first built it
Step-by-step explanation:
The equation is in the form
y = a b^x
The a is the initial value at time x =0
The b is the growth rate
x is the time
So
4 * 3^t
4 is the initial amount of ducks
3 is the growth rate, or the duck population increase by a factor of 3 each time period
t is the time period in years

Step-by-step explanation:
Question not written well
The equation of the ball is meant to be in a parabola or trajectory form.
So, h = -4.912t² + 24.5t + 1
The ball will hit the ground when the height is 0
I.e. h= 0
Therefore,
-4.912t² + 24.5t + 1 = 0
Using almighty formula,
a = -4.912 b = 24.5 c = 1
t = (-b±√b²-4ac) / 2a
t = (-24.5±√24.5²-4×-4.912 × 1) / 2 × -4.912
t = (-24.5±√600.25 + 19.648) / 9.824.
t = (-24.5 ± 24.898) / 9.824
So,
t = (-24.5 + 24.898) / 9.824
t = 0.398 / 9.824
t = 0.04seconds
Or
t = (-24.5 - 24.898) / 9.824
t = -5.03 seconds
So, we are going to discard the negative time,
t = 0.04 second is the correct time the ball will hit the ground
