Answer:
It will take 2.6 s for the ball to hit the ground.
Step-by-step explanation:
This is a standard physics problem
The equation that defines the movement of Ryans baseball is given by the initial velocity, and the acceleration
Distance = Do + Vo*t + 0.5*a*t^2
Where
Do is the initial distance.
(Do = 2m over the ground)
Vo is the initial velocity = 12m/s
a is the acceleration that is exerted on the body (in this case a = g = -9.8 m/s^2 )
t is the time
We substitute in the equation, and solve for t (time)
(0)= 2+ (12)*t + 0.5*(-9.8)*t^2
We get that
t = 2.606 s = 2.6 s
Answer:
The rate is 
Step-by-step explanation:
The rate, in cents per minute, is given by the multiplication of the how much you paid by 100 and divided by the number of minutes.
The multiplication by 100 happens because the cost is in dollars, and each dollar has 100 cents. So

Answer:
(g•f)(x) = x.
Step-by-step explanation:
Let
, then the inverse function of the f(x) is
So, (g•f)(x) =
Therefore, we can write if f(x) and g(x) are inverse functions of each other, then (g•f)(x) = x.
Hence, option D is correct. (Answer)
