Answer:

Step-by-step explanation:
The populational growth is exponential with a factor of 1.12 each year. An exponential function has the following general equation:

Where 'a' is the initial population (25,000 people), 'b' is the growth factor (1.12 per year), 'x' is the time elapsed, in years, and 'y(x)' is the population after 'x' years.
Therefore, the function P(t) that models the population in Madison t years from now is:
S(8)=((100×(1−(50÷100)^(8))÷(1−50÷100)))

Answer:
.79 mm^2
Step-by-step explanation:
First find the area of the circle
A = pi r^2
A = 3.14 (1) ^2
A = 3.14
Now we have 1/4 of the circle
The area is 1/4 of the full area
1/4 *3.14
.785
Rounding to the nearest hundredth
.79 mm^2

Answer:

Step-by-step explanation:
In order to find the values of a piecewise function, we first have to determine which piece we are using.
For
, x=-3. This means that we need to use
as 

For
, x=2. This means that we need to use
as x is equal to 2.
