Answer: 12.56 cm

Step-by-step explanation:

Pi looks like this <em>π or 3.14 or 22/7</em>

A formula for circumference is: <em>C = 2π r</em>

<em>The radius or r listed in the diagram is 2cm. </em>

1) Plug r into the equation...

<em>C = 2π 2</em>

<em>2) Simplify the equation</em>

<em>C = 4π</em>

<em>3) You can insert 4π to be exact in a calculator or do 4 x 3.14 (its still the same thing but you have to round if you are using this π)</em>

However both answers come out to be 12.56

Answer:

106250

Step-by-step explanation:

Ok so we know that in the first quarter the company sold 125000 units to people. But then suddenly they start losing 5%. Since we are told there are 3 quarters, we would have to do 5% plus 5% plus 5%, which amounts to 15% total lost in the three quarters. What we do now is we technically subtract that to 125000, so the equation would be 125000 minus 15%, and when you either use a calculator to help or your own mind, you get 106250 units sold.

Step-by-step explanation:

A is a model of exponential growth.

B is a model of exponential decay.

D is a "logistic function" model of growth in an environment of limited resources. It produces an "S" shaped curve.

The given bell-shaped curve can be described by the function of C, which decays either side of an axis of symmetry.
