Use the information to form an equation
x = width
x + 6 = length
perimeter = length + length + width + width
x + x + x + 6 + x + 6 = 44
4x + 12 = 44
4x = 32
x = 32/4
x = 8
width = 8 meters
length = 8 + 6 = 14 meters
The length of BC is 9cm
The length of DA is 45cm
We can solve this problem by determining how far the ball travels on each bounce. Once it has hit the ground the 4th time, it will have gone:
Down, up, down, up, down, up, down.
Now, we calculate how far each of these distances are.
Since the first drop is 10 feet, the ball will go up to 5 feet. Then it will fall 5 feet and go up 2.5 feet. The ball will then fall 2.5 feet, and rise 1.25 feet and fall 1.25 feet. Now, we add all these numbers up.
10 + 5 + 5 + 2.5 + 2.5 + 1.25 + 1.25 = 27.5, so the ball will have travelled 27.5 feet.
Answer:
2 and 4
Step-by-step explanation:
Answer:

Step-by-step explanation:
The average rate of change between two points on a graph is ...
average rate of change = slope = rise/run
The rise over the given interval is the function value at x=8 less the function value at x=5. That is, ...
rise = 1 - 10
The run is the difference in the x-values:
run = 8 - 5
Then the average rate of change is ...
average rate of change = rise/run = (1 -10)/(8 -5)
_____
Here, the points are written as (x, y), so the only pair we're interested in is ...
(5, 10) and (8, 1)
