Select "growth" or "decay" to classify each function. function growth decay y=200(0.5)^2t y=1/2(2.5)^t/6 y=(0.65)^t/4 which equation can be used to find the solution of (1/3)^d−5 = 81 ? a. −d−5=4 b. d + 5 = 4 c. d−5=4 d. −d+5=4

1. The growth rate equation has a general form of:

y = A (r)^t

The function is growth when r≥1, and it is a decay when r<1. Therefore:

y=200(0.5)^2t                    --> Decay

y=1/2(2.5)^t/6                  --> Growth

y=(0.65)^t/4                       --> Decay

2. We rewrite the given equation (1/3)^d−5 = 81

Take the log of both sides:

(d – 5) log(1/3) = log 81

d – 5 = log 81 / log(1/3)

d – 5 = - 4

Multiply both sides by negative 1:

- d + 5 = 4

So the answer is D
