Answer:

This is an Exponential Decay

Step-by-step explanation:

A = 1200(0.85)⁶

The above expression is an Exponential Decay because 0.85 is less than 1

The formula for Exponential Decay

= y = a (1 - r)^t

We equate both equation together

Where

a = 1200

1 - r = 0.85

t = 6

Solving for r

1 - r = 0.85

r = 1 - 0.85

r = 0.15

Converting to Percentage

r = 15% decay rate

Helppppp..... evaluate 3^-3=

elixir [45]

ANSWER

The answer is

$\frac{1}{27}$

EXPLANATION

The given expression is

${3}^{ - 3}$

Use the negative index property;

${a}^{ - m} = \frac{1}{ {a}^{m} }$

We apply this property to get:

${3}^{ - 3} = \frac{1}{ {3}^{3} }$

This gives us:

${3}^{ - 3} = \frac{1}{3 \times 3 \times 3 }$

${3}^{ - 3} = \frac{1}{27}$

The correct option is B.
