Answer:
Exponential Decay
Step-by-step explanation:
The base of the exponential term is <em>less than 1</em>, so the function represents decay.

I'm assuming you've already learned the special properties of a 30-60-90 triangle.
By drawing a 30-60-90 triangle by constructing line BC, and using the special proportions that come from it, we can find that
AB=AC/2=36/2=18
and
BC=AB*
=
Answer:
x = 15
Step-by-step explanation:
Assuming you require the value of x
The product of the external part and the whole of one secant is equal to the external part and the whole of the other secant, that is
9(9 + x) = 8(8 + 19), that is
81 + 9x = 8 × 27 = 216 ( subtract 81 from both sides )
9x = 135 ( divide both sides by 9 )
x = 15
Ok,
divide by 2 on both sides...


So X = 3/8!
