Betsy is shopping for a new rug, and she finds a square rug that she wants to purchase for her living room. before purchasing the rug, she needs to know the side measure. she knows that the area of the rug is a square feet. which of the following functions would best model the situation above? a.) square root b.) exponential c.) absolute value d.) cube root

A. square root is the right answer.

Step-by-step explanation:

Now we know that, Betsy finds a square rug that she wants to purchase for her living room and she needs to know the side measure.

Area of the rug is A square feet.

To model this situation, square root function is the best.

We know that area of square having side 's' =

A =

So,

Lets take an example.

Let the area of the rug be 25 square feet.

So, side will be :

side = 5 feet

Hence, the answer is square root function.

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.

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
