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

Step-by-step explanation:
look at the numbers, check how far apart they are.
The image of the triangles are missing and so i have attached it.
Answer:
Explained below.
Step-by-step explanation:
If we delete line AC in the diagram, we are left with line AB and BC.
Now, we are told to leave points B and C fixed.
Now, if we move Point A to different locations, ∠ ABC will increase or decrease depending on the new location that point A is put.
Lastly, if we move Point A to a point on line CB, it means ∠ABC = 0° because it isn't subtended at any angle at all.
Answer:
B. 20
Step-by-step explanation:
x + 40 = 3x
x - x + 40 = 3x - x
40 = 2x
20 = x
