and these are the questions
2: Raise the cannon to a height of 15 meters. Set the horizontal velocity to 12 m/sa) Sketch the situationb) Predict the distance you have to place the target from the base of the cannon (calculate this & show all work).
c)Perform the experiment by placing the target at the predicted range and clicking the cannon button. Compare your predicted value to the outcome of the testing experiment. Do they agree or disagree? (Did you hit the target?)
3: Raise the cannon to a height of 5 meters. Measure the distance of the David statue from the base of the cannona) Sketch the situation.b) Predict the velocity with which you have to launch the object in order for it to hit the statue (calculate this & show all work).c)Perform the experiment by entering the predicted velocity and clicking Fire. Compare your predicted value to the outcome of the testing experiment. Do they agree or disagree? (Did you hit the statue?) If they disagree, look at your math again!
4: Set the initial velocity of the object to 20 m/s. Place the target at a range (distance) 20 m.a) Sketch the situation.d) Predict the height from which you have to launch the object in order for it to land on the target (calculate this & show all work).b) Perform the experiment by raising the cannon to the predicted height and clicking Fire! Compare your predicted value to the outcome of the testing experiment. Do they agree or disagree? (Did you hit the target?) If they disagree, look at your math again!
Activity A2-4 is on page 78 of your textbook. It asks you to go to finance.yahoo.com and enter the ticker symbol for Apple Corporation stock (AAPL). A page will open up which contains information on Apple, including interactive charts which allow you to see the movements in Apple's stock price over a selected period of time. Also included are Apple's most recent financial statements. Find the most recent financial statement information (not the 2008 information that is contained in the solution posted on the Blackboard site). Activity A2-4 then asks 10 questions about information that is contained in the financial statements. For example, question #7 asks what the annual dividend is on Apple stock. Take turns finding the answers to these questions until all 10 questions have been answered. Then think about whether you would invest money in Apple stock right now. Do you think it is over or under-priced? Why?

d 5 cm wide. The area of the rectangle is 15cm squared. What is the height of the rectangle?
The second question is on another rectangle, the height is a and the width is 3a. The perimeter is 24cm. What is the length of the shortest side.
is Imagine that in the voting for a certain award, 7 points are awarded for first place, 4 points for second, 3 points for third, 2 points for fourth, and 1 point for fifth. Suppose there were five candidates (A, B, C, D, and E) and 47 voters. When the points were tallied, A had 155 points, B had 173 points, C had 170 points, and D had 154 points. Find how many points E had and give the ranking of the candidates. (Hint: Each of the 47 ballots hands out a fixed number of points. Figure out how many, and take it from there.)
