BELLRINGER Get out a piece of paper

The birth rate in New Brunswick in was reported as 10.1 per 1000 people. The birth rate in Nova Scotia was reported as 9.9 per 1000 people. a) can you tell from this information which province had more births in that year? Explain

The Purpose of the Bellringer was to show how to interpret the information located in a word problem GIVEN: –the rate of change. NOT GIVEN: –the total population for each region THEREFORE: –There is not enough information given to tell you which region had the most births in a single year.

INTRODUCING GROUP PROJECT

Group Project Quadratic Word Problem Assignment Create a unique word problem that needs to be solved using a quadratic equation Solve the word problem with a complete solution and explanation (at least 3 steps) - Present in Class Illustrate your problem and the solution on a poster

Example 1. Graph the flight paths of 5 different birds from the phone application "ANGRY BIRDS." 2. Calculate the highest point in each flight path (the vertex)

Example (continued) 3. Below the graph are the solutions for each flight pattern 4. Present steps on how you found the solution to the problem you created

Special Notes Equal to or less than 4 per group You will be graded on originality, accuracy, and by using the most efficient method to find your solution –POSSIBLE METHODS: creating a sequence finding a by dividing the D2 common difference divided by 2 -b/2a = (to find the x-value of the vertex) converting from standard form to factored form or vice versa converting from standard form to vertex form or vice versa quadratic formula:
