Answer:
b8
Step-by-step explanation:
Tan of an angle = perpendicular / base
<span>Here, perpendicular is the side of the triangle opposite the angle. </span>
<span>And base is the arm of the angle other the hypotenuse. </span>
<span>If the side of the triangle to be found (marked as ? in the figure) is x, then </span>
<span>perpendicular = 20 feet </span>
<span>base = x </span>
<span>so, tan 30 = 20/x </span>
<span>so, x = 20/(tan 30 degrees) = 34.64 feet </span>
<span>= 35 feet to the nearest foot</span>
Growth means a base for exponentiation bigger than 1 (in absolute value), otherwise it's decay.
Only the first choice has a base biggerthan 1. The last choice is equivalent to 
so has a base less than 1.
