Answer:
The average rate of change is -0.034 which means that the decrease is -0.034 in the cost of per print per year
Step-by-step explanation:
Given that
Price of print in 2002 = p1 =$0.50
Price of print in 2013 = p2 =$0.13
y1 = 2002
y2 = 2013
The rate of change is given by the formula:

Here decrease is the change in price and run is the difference in years.
Mathematically, it can be written as:

Putting the values

Hence,
The average rate of change is -0.034 which means that the decrease is -0.034 in the cost of per print per year
Answer:
equal to
Step-by-step explanation:
A circle with a diameter of 2x has a radius of x, so will have the same area as a circle with a radius of x.
Answer:
60 ft²
Step-by-step explanation:
You can divide the figure into 2 parts.
First, solve for the rectangle: Area of a rectangle = b*h = 4ft x 10ft = 40ft²
Then, solve for the triangle:
Height = 10ft - 5ft = 5ft
Base = 12ft - 4ft = 8ft
Area of a triangle = (b*h)/2 = (5ft x 8ft)/2 = 20ft²
Just add them together: 20ft² + 40ft² = 60ft²
