At the time the cannonball reaches the ground, the vertical height of the cannonball from the ground is 0, i.e. h = 0.
Thus, the time it will take the cannonball to reach the ground is given by
Therefore, it will take the cannonball 8 seconds to reach the ground.
X=3
Step by step solution-
You subtract both sides by 2,
2/3x= 2
Then divide both sides by 2/3 to isolate the x.
2/ (2/3) = 3
Therefore, x=3

The answer is B, your welcome
Answer:
B
Step-by-step explanation:
The graph begins up and ends down. This means as x heads into negative infinity the graph continues up, up and up towards infinity. While x heads to positive infinity on the right side of the graph, the graph heads down, down, and down towards negative infinity. See graph below.
Answer:
Average speed = 4 mph
Step-by-step explanation:
Given as
Total distance to travel = 6 mile
now, for first 2 mile the avg speed = 6 mph
for next 2 mile the avg speed = 4 mph
and for rest 2 mile the avg speed = 3 mph
so, the average speed of the Richard = 
Total Avg speed = 
Or, = 
×12
= 4
So the total Average speed = 4 mph (Answer)
