a rectangle is always a parralellogram. Always True. Since a rectangle is below the parallelogram in hierarchy, it inherits all the properties of a parallelogram. Therefore, it is a parallelogram in every case.   Question: Sketch an example of when it is true and an example of when its not. Explain thoroughly and add values to justify the explanation.

Regal Theatre puts on community theatre productions each season. After several years of gathering data, they noted some trends between the length of the plays they produced and the number of tickets they sold for Friday evening shows. They created the model shown below Hrs played       ticket sold 1                        119 1.5                     139 1.75                  145 2                        149 2.25                   150 2.5                   149 3                      139 4                        89 a) What does the ordered pair (3,139) represent in the context of this situation? b) Determine the function's average rate of change over each of the following intervals. Make sure to describe how to interpret the meaning of the average rate of change in each case.   i) 1≤x≤2.25     ii) 2.5≤x≤4   c) Does the function have positive concavity or negative concavity (or a combination of the two)? What does this tell you about the situation?
