Finals week

From Friday to Tuesday there will  be finals for periods 2-6.  Check the school website for the schedule and prepare!


Enjoy your summer and see you next year.

Thursday 6/6

pre calc -  last time to review before finals.   Adios seniors!



alg I -   Last time to review before finals.  You may need to go to older posts to see the review guide if you are trying to use it to study.  Today we did 12-20 on it and turned it in.

Wednesday 6/5

pre calc-   another study session for the non seniors.  Senior goodbyes!



alg I -    prepping for the final by doing review guide problems.

Tuesday 6/4

pre calc -   Hey, if you are a senior...this was it!!  Congrats, I really enjoyed this class and wish you all well.  Juniors, you got yours coming up so be ready.



alg I -  We did our final 8 boards today and we explored desmos again comparing linear and exponential models.
All classes have a final coming up so do the problems in the study guide and ask any questions before the final.

Monday 6/2

pre calc -   semester review as the seniors have their final tomorrow!  Study and good luck!!!




alg I -  If you did stomp rockets, you calculated your velocity from Friday.  There was a warm up 23 and we finished the class with a desmos activity on linear functions.
Final review guide is out.  Anyone looking to increase or protect their grade should start studying ASAP.

Friday 5/31

pre calc -   without our beloved seniors, it was very quiet.  Spent most of the period on desmos working on sinusoids.



alg I -   Went over the perf task and quad test.  One class was able to do stomp rockets.  Other classes has some algebra work to complete and turn in.

Algebra I Quadratics Review Guide for test 5/24

There will be a unit test (the last one!) on Friday.  It is very comprehensive of the whole unit; in other words, there is a lot of graphing and vocab on the test and  not just solving equations.

There are 8 questions, though some will have multiple parts.

5 Solving quadratic equations - you can use any method.  All will have real solutions.
6 on quadratic equation vocab -  vertex, roots, solutions, maximum/ minimum, parabola, standard form, quadratic equation, quadratic formula
1 graphing a quadratic
1 finding the vertex
1 putting a quadratic equation into standard form
1 reading a parabolic graph that matches a real world situation


Be able to:

solve:  (x+1)(x - 5) = 0

solve: x^2 +8x +7 = y

solve:  x^2 - 2x = 5

solve:  2x^2 - 11x + 5 = 0

solve:  4x^2 - 14 = 18   (yes that is a 14 and not a 14x)

graph:  y= 2x^2 - 8x + 7

what is the maximum value of y = -3x^2 +18x + 1?

Put the following into standard form:  y = (2x+3)(x - 6) + 2

If a golf ball is hit and its height is modeled by h = -16t^2 + 48t, when does it hit the ground?


ANSWERS:
1.  x= -1, 5
2. x = -1, -7
3.  x = 1 +/- sq rt 6
4. x = 0.5, 5
5. x = +/- sq rt 8
7. ( 3, 28)
9.  t = 3 seconds
