To check for the correlation, simply look at both the age and the cost values, since as age increases the cost decreases, there is a negative trend, since the cost is decreasing as one increases.
The actual amount can be approximated, because the amount is not going down as quickly it goes down slowly it would probably be -0.05.
This is a weak negative.

Answer: Vertical Stretch
Step-by-step explanation:
Given: The cost of manufacturing x refrigerators is given by the function :![f(x)=2x^2+6000](https://tex.z-dn.net/?f=f%28x%29%3D2x%5E2%2B6000)
If the cost doubles fr the year 2011 owing to higher raw material prices, then we multiply the given function by 2, then we get a new function :
which represents a vertical stretch in the graph.
∵ 2 is a positive constant greater than 1 which is multiplied to the parent function f(x). So by the definition of vertical stretch the parent function will be vertically stretched .

Step-by-step explanation:
Diameter is any line that passes through the center of a circle (shown by the point). The radius is anyline that orginates at the center and goes outwards from the circle.
