the pattern continues, what will we see in Step 5 and Step 18?
Sketch or describe the figure in each of these steps.
How many small squares are in each of these steps? Explain how you know.[br]
Write an equation to represent the relationship between the step number [math]n[/math] and the number of squares [math]y[/math]. Be prepared to explain how each part of your equation relates to the pattern. [br](If you get stuck, try making a table.)[br]
Sketch the first 3 steps of a pattern that can be represented by the equation y = n² - 1.
For the original step pattern in the statement, write an equation to represent the relationship between the step number [math]n[/math] and the perimeter, [math]P[/math].[br]
For the step pattern represented by the equation [math]y=n^2-1[/math], write an equation to represent the relationship between the step number [math]n[/math] and the perimeter, [math]P[/math].[br]
Are these linear functions?[br]
Here is an image showing a pattern. Sketch the next step in the pattern.
Kiran says that the pattern is growing linearly because as the step number goes up by 1, the number of rows and the number of columns also increase by 1. Do you agree? Explain your reasoning.[br]
To represent the number of squares after [math]n[/math] steps, Diego and Jada wrote different equations. Diego wrote the equation [math]f\left(n\right)=n\left(n+2\right)[/math]. Jada wrote the equation [math]f\left(n\right)=n^2+2n[/math]. [br]Are either Diego or Jada correct? Explain your reasoning.[br]

Write an expression for the area of the shaded part of Figure B.
Here are a few pairs of positive numbers whose difference is 5. Find the product of each pair of numbers.
Then, plot some points to show the relationship between the first number and the product.
Is the relationship between the first number and the product exponential? Explain how you know.[br]
Here are some lengths and widths of a rectangle whose perimeter is 20 meters. Complete the table.
What do you notice about the areas?
Without calculating, predict whether the area of the rectangle will be greater or less than 25 square meters if the length is 5.25 meters.[br]
On the coordinate plane, plot the points for length and area from your table.
Do the values change in a linear way? Do they change in an exponential way?

Mai has a jar of quarters and dimes. She takes at least 10 coins out of the jar and has less than $2.00.
Write a system of inequalities that represents the number of quarters, [math]q[/math], and the number of dimes, [math]d[/math], that Mai could have.[br]
Is it possible that Mai has each of the following combinations of coins? If so, explain or show how you know. If not, state which constraint—the amount of money or the number of coins—it does not meet.[br][br][list][*]3 quarters and 12 dimes[br][/*][/list]
[list][*]4 quarters and 10 dimes[br][/*][/list]
[list][*]2 quarters and 5 dimes[br][/*][/list]
A stadium can seat 63,026 people. For each game, the amount of money that the organization brings in through ticket sales is a function of the number of people, [math]n[/math], in attendance.[br][br]If each ticket costs $30.00, find the domain and range of this function.
