Thank you those of you who participated in the World-Wide Kahoot challenges! Here are the pictures of who was on the the Podium. If you have ideas on more challenges let me know in the comments! I could only get a few of them because some weren’t participated in or there wasn’t anybody in them that were done. As a reminder, when you join the kahoots make sure that you COMPLETE the kahoot fully. Thank you again for participating, once again if you have ideas for more challenges let me know in an answer or a comment. Congratulations on those who were on the podium and those that participated but didn’t make it on the podium.

What is the largest decimal number that can be represented by a binary number with 4 place values? (remember, each place in a binary number has a value of a power of 2, starting in the ones place with 20.)

Agood flowchart alludes to both the inputs and outputs you will need to receive and give to the user. true or false?

The volume v and paper surface area a of a conical paper cup are given by where r is the radius of the base of the cone and h is the height of the cone. a. by eliminating h, obtain the expression for a as a function of r and v. b. create a user-de ned function that accepts r as the only argument and computes a for a given value of v. declare v to be global within the function. c. for v ! 10 in.3 , use the function with the fminbnd function to compute the value of r that minimizes the area a. what is the corresponding value of the height h? investigate the sensitivity of the solution by plotting v versus r. how much can r vary about its optimal value before the area increases 10 percent above its minimum value?
