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:
(3,4)
Step-by-step explanation: I'm assuming you want to know the final point you end up at. The first part of our coordinate pair is our x value, so we want to reduce our x-value by 4 to go left 4 units, the second part is our y-value, we want to reduce it by 1 to go down 1 unit. So, our final coordinate pair is (7-4,5-1) or (3,4).
Hello!
The sum of 5/6 and 1/2 is 1 1/2
5/6 > 3/4 so round it to 1.
1/4 ≤ 1/2 ≤ 3/4 so round it to 1/2.
Estimating:
1 + 1/2 = 1 1/2
The difference of 5/6 and 1/2 is 1/2
5/6 > 3/4 so round it to 1.
1/4 ≤ 1/2 ≤ 3/4 so round it to 1/2.
Estimating:
1 - 1/2 = 1/2
Hope this helps!
