Extra Credit Question

In game 2 of this years World Series Derek Jeter hit a ball to center field in the new Yankee stadium. The ball that Derek hit can be modeled by the equation
y = -0.0024x^2 + x + 3. The centerfield fence is 400 feet away from home plate and the fence is 6 feet tall.
a) Was the hit a homerun?
b) Would it be a homerun if the fence was 20 feet high?

You must show your work and write two sentences explaining how you came up with your answer.

Hint: The only thing you care about is how high (the y value) the ball is above the ground when the ball was at 400 feet (the x value) from home plate. You can use a graphing calculator or even make a t-table to answer this question.

Math 2 On Monday

In class today we worked on finishing our application project. These problems involved using 30-60-90 and 45-45-90 triangles to solve "real world" problems. Homework for tonight was page 153 7-14. Remember that we will have our quiz on Thursday. Listed below are 3 links where you can go to get more practice solving triangle problems.

How to Find the Area of a Triangle Using Pythagorean Theorem

Watch the following video. This shows how to find the area of a triangle when you must calculate the height. Remember Area = 1/2 b * h for a triangle. This is similiar to the problems we worked in class. By the way, you will see one of these on the quiz on Tuesday.

New Technology - A Way to Communicate

Welcome to my math classroom blog. I am trying a new technology that I am learning about from Georgia State University. This blog will be used as a sort of diary detailing what we learned about that day in class. I will restate the essential question that we talked about and highlight the main ideas. I will also include what was assigned for homework (in case you forgot to write it down). You can reply with any questions or comments about this site or about what we went over in class. Remember, this is new to me so help me make the best use out of this new technology.
