4. A-REI.4.11 A company is considering building a
manufacturing plant. They determine the
weekly production cost at site A to be
A(x) = 3x2 while the production cost at site
B is B(x) = 8x +3, where x represents the
number of products, in hundreds, and A(x)
and B(x) are the production costs, in
hundreds of dollars. State the positive
value(s) of x for which the production costs
at the two sites are equal. Explain how you
determined your answer.

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.

use formula for the circle a=3.14

step-by-step explanation:

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
