Part 1 You will need to measure five different people. Record your measurements on a piece of paper. Using a tape measure or ruler, measure the length (in inches) of a person’s left foot and then measure the length (in inches) of that same person’s forearm (between their wrist and elbow). Refer to the diagrams below. You will have two measurements for each person. (An easy way to measure the length of a foot is to have your subject stand on a piece of paper. Then, trace their foot and measure the outline once they move off the paper.) To measure the forearm, measure inside the arm, between the wrist and the elbow. Part 2 Organize your data and find the rate of change. Create a table of the measurements for your data. Label the forearm measurements as your input and the foot measurements as your output. Select two sets of points and find the rate of change for your data. Describe your results. If you had to express this relation as a verbal statement, how would you describe it? Part 3 Compare rates of change. The equation below can be used to find the length of a foot or forearm when you know one or the other. (length of the foot) = 0.860 • (length of the forearm) + 3.302 If you let y = length of the foot and x = length of the forearm, this equation can be simplified to y = 0.860x + 3.302. Using this equation, how long would the foot of a person be if his forearm was 17 inches long? What is the rate of change of the equation from Part A? Compare the equation from Part A to your data. Are they the same? Which has a greater rate of change? Why do you think the values are different? Is the relation in your data a function? Why or why not? Could the equation in Part A represent a function? Why or why not? Explain your answer.

Answer:

Part 1 and 2:  

A. Forearm (in)        Foot (in)                      

Sarah   10                9

Sam   11.               10

Emma  8                  7

Mom   10                 9

Dad  11                 10  

B. M=9-7 over 8-10 the answer is 2 over 2.

C.  For every forearm the foot is one inch smaller.

Part 3:

A. 0.860(17)+3.302

B. Y=17.922. They are slightly different.  Keren’s has a greater rate.  I think the values are different because they have different origins.

C. Yes, because it is an important part for rate of change. Yes it is a function because there can’t be any exponents greater than 1, and its not a straight line if you plug it in.

Step-by-step explanation:

This is just an example dont you the names

The table below shows the measurement of five different peoples and if I had to express this relation as a verbal statement, I would describe it as "The foot is one inch smaller for every short arm" and this can be determined by using the given data.

Part 1  and 2 --

Given :

The table below shows the measurement of five different peoples.

Name          Forearm (inches)           Foot (inches)

Shruti                      10                                  9

Ali                            11                                  10

Alvi                           8                                    7

Tanisha                    10                                   9

Swati                         11                                   10                                    

The two sets of points in order to find the rate of change for your data are:

M = 9 - 7 over 8 - 10 so, by simplifying this the solution is 2 over 2.

If I had to express this relation as a verbal statement, I would describe it as "The foot is one inch smaller for every short arm".

Part 3  --

Given :

y = 0.860 x + 3.302

The foot of a person if his forearm was 17 inches long is given by:

y = 0.860(17) + 3.302

y = 14.62 + 3.302

y = 17.922

So, the foot of a person if his forearm was 17 inches long is 17.922.

By comparing the equation from part A to the data it can be concluded that they are slightly different.  

The greater rate of change is of Keren’s and I think the values are different because they have different origins.

Yes, the equation in part A represents a function because there are no exponents greater than 1.
