Answer:
19.85
Step-by-step explanation:
158.80 divided by 8 is 19.85
Exponential growth is the function

Exponential decay is the function

So, the basic difference is that in growth the base is more than 1, and in decay the base is more than 0 but less than 1.
A,C,and D are all correct
Area of circle = πr²
1075.21 = πr²
1075.21/π = r²
r = √1075.21/π
r = 18.5
If you draw a diagram of this, your given values of the resulting triangle give you the sides opposite and adjacent of the angle. The formula that uses these sides is tangent.
The tangent of an angle is equal to the ratio of the opposite side over the other non-hypotenuse side (adjacent).
Therefore;





Where x is the length of the string in feet.
