Without an equation, it's impossible to answer your question. I'm sorry.
Answer:
The domain is all real numbers. The range is {y|y ≤ 16}.
Step-by-step explanation:
The vertex of a parabola is given by
.
As a = -1, b = -2, c= 15 here, then the vertex is at (1,16).
As a is negative, it opens downward, so the range is {y|y ≤ 16}.
Meanwhile, all parabolic functions have a domain of 
.
Answer:
Step-by-step explanation:
Sampling error occurs when the sample used by the research is not a representative of the whole population. While a non sampling error occurs during data sampling due to other factors than taking a sample.
Since there were no errors in collecting the data during day sampling, and it is safe to assume that the sample taken was a representative of the population, we can conclude that this is a non sampling error that was due to other factors than taking a sample.
Answer:
20cm
Step-by-step explanation:
Given data
Radius= 4cm
Circumference= 20π
Let CD be the diameter of circle A
C= 2πr
20π= 2πr
10= r
Diameter= 2*r
D= 20cm
Hence the diameter CD= 20cm
