Notes for Monday, 10/28: page 18: Angle with vertex outside the circle created by two tangents:
Video for notes on page 25: Inscribed angles (special cases)
Thursday we started Unit 6: Characteristics of Quadratics. Below is a picture of the notes we took and a couple of problems worked out.
Friday we took notes on transformations of quadratics. The equations should be in vertex form.
If the "a" value is negative, the graph is reflected over the x-axis.
If the absolute value of "a" is greater than 1, it is a stretch.
If the absolute value of "a" is between 0 and 1, it is a shrink.
If the "h" value is positive, it is a shift right.
If the "h" value is negative, it is a shift left.
** BE CAREFUL WITH THE "H" VALUE. THE "H" VALUE IS THE OPPOSITE SIGN FROM WHAT IS INSIDE THE PARENTHESIS.
If the "k" value is positive, it is a shift up.
If the "k" value is negative, it is a shift down.
Below is a picture of the notes from Friday:
Friday, October 25th: We took notes on pages 11, 12 and 13 in the packet for solving angles and arc problems. The formulas on page 11 are NOT on the formula sheet, so you will have to memorize them.
Homework: Evens on pages 14, 16 & 17.
Below are videos explaining the notes:
