Answer:
5/8
Step-by-step explanation:
the range is the largest number minus the smallest number so
1 1/4 - 5/8
5/4 - 5/8
you would take 5/4 *2 to get like denominators so,
10/8-5/8= 5/8
The formula that you will use will be the formula for the area of a circle, which is as follows:
A= Pi r^2
(Pi times the radius squared)
Given :
A boat is being pulled into a dock with a rope attached to the boat at water level. When the boat is 12 feet from the dock, the length of the rope form the boat to the dock is 3 feet longer than twice the height of the dock above the water.
To Find :
The height of the dock.
Solution :
This will make a right angle triangle as given in link below .
Now , applying Pythagoras theorem :

Now , h = 5 or h = -9 .
Now , height cannot be negative .
So , height of the dock is 5 ft .
Hence , this is the required solution .
The answer is actually 1.571
