Week of April 20th

Algebra 2H pds 1,2
We graphed conic section inequalities and started to solve systems of equations with conics and lines. We will solve these problems algebraically.
HW page 607 # 1,3,7,9, and 11
EC problems #6 and # 12.

Geometry H pds 3,5,6
Today, we worked on a concept lesson to determine the best type of container for selling chocolate. The choices were a cylinder, square prism, and triangular prism. Most students were surprised that the cylinder container had the most volume.
We also learned that doubling or tripling the dimensions of a rectangular prism make the volume cubed and the surface area squared.

EC problem---How did today's lesson help you to better understand volume and area of containers with the same height but different bases?
