Periods 2 and 3
We continued our work with inverse variation using the concepts found in Problems 3.2 and 3.3.
By comparing different circumstances we were able to see that the idea of inverse variation can be applies to many different cases. The constant of variation might change as well as the independent and dependent variables, but the pattern we have observed remains the same. Knowing this makes it possible to predict the kind of graph we can expect and also what the equation will look like.
Assignment: Period 2—none; Period 3—p. 53, #1 and #2.
We continued our work on scientific notation. Today we multiplied and divided numbers that are in scientific notation. Sometimes, in these cases, the product or quotient has to be adjusted so that the decimal is between 1 and 10. When this occurs the power of 10 must also be changed.
We also applied this to word problems, using very small numbers.
Assignment: p. 516, #39 -44, 51 -53.
