the relationship of the rectangles and the figure number is QUADRATIC.

The graph is also attache below.

Step-by-step explanation:

As we check that

Figure 1 has 1 rectangle.Figure 2 has 3 rectangles.Figure 3 has 6 rectangles.

Mapping this information in data set as follows.

x (Figure Number) 1 2 3

y (Number of Rectangles) 1 3 6

Here, x represents the Figure number and y represents the number of rectangles.

CHECKING IF THE RELATIONSHIP IS LINEAR

Taking the common difference of y-values

3 - 1 = 26 - 3 = 3

As the common difference between two values is not same. Hence, the relation can not be linear.

CHECKING IF THE RELATIONSHIP IS EXPONENTIAL

Now, taking the common ratio of y- values.

3/1 = 36/3 = 2

As the common ratio between two values is not same. Hence, the relation can not be exponential.

Since, the relationship is NEITHER linear NOR exponential as we have checked. Lets check if the relationship is quadratic or not.

CHECKING IF THE RELATIONSHIP IS QUADRATIC

Now, let us see if the data set may establish any pattern.

i.e.

As the y-values are showing a pattern such as:

1 + 2 = 3

3 + 3 = 6

so the next term can be obtained by following the same pattern such as

6 + 4 = 10

10+ 5 = 15

15 + 6 = 21

So, the y values become 1, 3, 6, 10, 15, 21,...

In order to check the quadratic relationship between the pattern of y-values, we need to check whether the second common different is constant or not.

If the second common difference remains same, then this relationship will be quadratic.

So,

3 - 1 = 2

6 - 3 = 3 → 3 - 2 = 1 (second common difference)

10 - 6 = 4 → 4 - 3 = 1 (second common difference)

15 - 10 = 5 → 5 - 4 = 1 (second common difference)

21 - 15 = 6 → 6 - 5 = 1 (second common difference)

From the above calculation we determine that the second common difference remains same. Therefore, the relationship of the rectangles and the figure number is QUADRATIC.

Me! i'm really confused the isosceles trapezoids, abcd and efgh, are similar quadrilaterals. the scale factor between the trapezoids is 2: 3, line gh = 6 centimeters, line ad = 8 centimeters, and line ab is three times the length of line dc . use complete sentences to answer the following prompts and include all of your calculations in your final answer. a. write a similarity statement for each of the four pair of corresponding sides. b. write a congruence statement for each of the four pair of corresponding angles. c. determine the perimeter for each of the isosceles trapezoids.
