This should be it have a great day buddy!
Given:
The number is -10.
To describe the number:
Explanation:
Since 10 is a whole number and it has a minus sign.
So, -10 is an integer number.
Since it is an integer number.
So, it must be a rational number as well as the real number.
Therefore, -10 is a number that belongs to the sets

repeating
The average decrease in value can be solve by first solving the value at year 1 and year 2
and i think the equation is <span>f(x)=10,000(0.73)^x</span>
at x = 1
<span>f(x) = 10,000(0.73)^x
</span><span>f(1) = 10,000(0.73)^(1)
f(1) = 7300
at x = 2
</span><span>f(x) = 10,000(0.73)^x
</span><span>f(2) = 10,000(0.73)^(2)
f(2) = 5329
so the average decrease = ( 7300 - 5329) = $ 1971 per year</span><span>

Answer:
the height of the tree is 19.2 ft
Step-by-step explanation:
Given;
distance from the foot of the tree, d = 15 ft
angle of elevation; θ = 52°
let the height of the tree = h
Make a sketch of the problem as follows;
↑
↑ h
52°---------------------
15 ft
If completed to form a right triangle by adding the hypotenuse side, we can calculate the height of the tree as follows;
Therefore, the height of the tree is 19.2 ft
