Answer:
Option B is correct.
Initial amount (a) = 30 and growth factor(b) = 8.3
Step-by-step explanation:
An exponential function is of the form:
....[1]
where
a represents the initial amount
b represents the growth factor and x is the variable
Given the function: ![A(x) = 30 \cdot (8.3)^x](https://tex.z-dn.net/?f=A%28x%29%20%3D%2030%20%5Ccdot%20%288.3%29%5Ex)
On comparing given equation with [1] we get;
a = 30 and b = 8.3
Therefore, the initial amount(a) = 30 and growth factor(b) = 8.3
That’s 29 I thinking I don’t know

Answer:
The correct option is A. The height of tree is 60 ft.
Step-by-step explanation:
From the given figure it is noticed that the building is creating a right angle triangle from a point and the tree divides the hypotenuse and base in two equal part.
According to midpoint theorem of triangle: In a triangle, if a line segment connecting the midpoints of two sides, then the line is parallel to third side. The length of line segment is half of the length of third side.
Using midpoint theorem of triangle, we can say that the length of tree is half of the building.
![Tree=\frac{1}{2}\times Building](https://tex.z-dn.net/?f=Tree%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20Building)
![Tree=\frac{1}{2}\times 120](https://tex.z-dn.net/?f=Tree%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20120)
![Tree=60](https://tex.z-dn.net/?f=Tree%3D60)
Therefore correct option is A. The height of tree is 60 ft.
