Select "Growth" or "Decay" to classify each function.
allochka39001 [22]

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

Solve the following automotive-services problems based on the examples shown previously. Voltage = 12 v Current = 48 amps Resist
yawa3891 [41]
For this case the first thing you should know is that we have the following definition:
 V = I * R
 Where,
 V: voltage
 I: current
 R: resistance
 Therefore, by clearing the Resistance we have:
 R = V / I
 Substituting the values:
 R = 12/48
 R = 1/4 ohms
 Answer:
 The value of the resistance is: 
 R = 1/4 ohms
