Answer: The answer is 1833 heads and 11 hours, 11 minutes.
Step-by-step explanation: Given that the Magic Dragon has 2013 heads. The brave Leo is cutting off the Dragon's heads at a speed of 5 heads per minute. But, the Dragon's heads are growing back at a speed of 2 heads per minute.
So, the number of heads of Dragon that are decreasing per minute = 3.
Therefore, after 1 hour, i.e., 60 minutes, The number of heads of the Dragon
= 2013 - 60 × 3 = 2013 - 180 = 1833 heads.
Now, the fight will last until all the heads of the Dragon are cut. Let the fight lasts for 'x' minutes, then
Hence the fight lasts for 671 minutes, i.e., 11 hours and 11 minutes.
Thus, the Dragon will have 1833 heads after 1 hour and the fight will last for 11 hour and 11 minutes.
Compute successive differences of the terms.
If they are all the same, the sequence is arithmetic and the common difference is the difference you have found.
If successive pairs of differences have the same ratio, the sequence is geometric and the common ratio is the ratio you have determined.
Example of arithmetic sequence:
1, 3, 5, 7
Successive differences are 3-1 = 2, 5-3 = 2, 7-5 = 2. All the differences are 2, which is the common difference of the sequence.
Example of geometric sequence:
1, -3, 9, -27
Successive differences are -3-1 = -4, 9-(-3) = 12, -27-9 = -36. These are not the same, so the sequence is not arithmetic. Ratios of successive pairs of differences are 12/-4 = -3, -36/12 = -3. These are the same, so the sequence is geometric with common ratio -3.

You are going to use the concept of similar triangle.
∆CED≡∆CBA
This is because they share the angle at C and also they both have an angle of 90o.
Let EC = X, then BE = 2.5X. So, BE = (X + 2.5X) = 3.5X
The scale factor EC/BC=x/3.5x=2/7
EC/BC=ED/BA=2/7
BA=7/2×63 in
The height of the tree = 220.5 inches. This is equal 18 feet and 4.5 inches.

You order the y-values from greatest to least, which are 2, 2, 3, and 4. You don't need to duplicate the same y-values, so the range is {2, 3, 4}
