Answer:
The tree is 20.6 ft tall.
Step-by-step explanation:
Please check the attached graph.
From the diagram, it is clear that John is 5 ft tall is standing 20 feet away from a tree, making an angle of elevation to be 38⁰.
The diagram makes a right-angled triangle.
- Given the angle = Ф = 38⁰
- Hypotenuse = Tree length = c ?
Pythagorean Theorem:
For a right-angled triangle, with sides 'a' and 'b', the hypotenuse 'c' is defined as:

substituting a=5, b=20


ft
Thus, the tree is 20.6 ft tall.
The second line
least to greatest: -3, -2.4, -21/4, -1.5, -11/8
Plug in the volume and radius into the formula, then multiply.
Answer:

Step-by-step explanation:
Hello,
At the beginning the population is 240,000
After 1 year the population will be
240,000*(1+7.75%)=240,000*1.0775
After n years the population will be

So after 7 years the population will be

So rounded to the nearest whole number gives 404,699
Hope this helps
