Classroom rules:
1. Park your phone on the whiteboard ledge within 10 seconds after entering the classroom.
IF YOU USE YOUR PHONE IN THE CLASSROOM YOU WILL SEE IT NEXT TIME AT 3.55 PM.
NO EXCEPTIONS. No head phones or ear buds.
Your phones will be retrieved when I tell you, about 3 minutes before the class ends,
row by row. After you get your phone, go back to your seat.
2. Sit in your assigned seat. Stay in your seat until bell the rings.
3. Computer and notebook up.
4. Look at the agenda. Do what the agenda says!
5. Do not pack up before I tell you to get your phone
(about 3 minutes before the end of class)
6. Be quiet from the bell rings until it is time for classwork (CW),
which usually takes place the last 30 minutes of the period.
TALKING DURING INSTRUCTION MEANS THAT YOU LOSE SOME
OF YOUR WEEKLY PARTICIPATION POINTS.
7. During classwork (CW) you can talk with a low volume
about math with your neighbors, but no LOUD talking/laughing.
8. No eating/drinking (except for water). No cursing.
9. DO NOT ASK TO GO TO THE RESTROOM DURING INSTRUCTION unless
it is an emergency. Do not go to the restroom often in my class.
Do not be gone for more than 5 minutes. Sign out, sign in when
you come back and remember to put the restroom pass back!
10. Do the CW and the homework (HW). If you do not do any CW
you will lose your weekly 100 participation points.
HW will be checked on a weekly or biweekly basis, but should be done every
day if you do not finish the CW/HW in class. If you procrastinate you will not have
time to finish your HW. You will get 100 or 200 points for the HW.
Since you can not use your phone, I recommend that you buy a calculator, TI 30 x is a great one because it is using solar cells.

Video (Black Jack for beginners):

Notes on Black Jack probabilities (105, top third only if short of time)
TIPS: Look at the dealers cards. If dealer has a lousy hand on the first card like 2-6,
then you should stay even if you have a low hand like 12-16. The reason is that the dealer
is running a high probability of going over 21.
However, if the dealer has a good first card like 7-11, then take a card if you have 12-16.
The reason is that dealer has a high chance of getting a 10 and will then have a better hand than you.
If you have 9,10 or 11 on your first two cards then you are allowed to "double down",
which means if your initial bet was $10, then you can now bet another $10.
You should do it if you have a better card than the dealer. For example you have 9, the dealer has 8.
TIPS IF YOU ARE THE DEALER:
Give one card face up to each player (going from left to right) and one to yourself.
Give a second card face up to each player and one to yourself BUT THIS ONE FACE DOWN.
Tell each player what the sum of their cards is and ask if they want another card.
Each player says (or shows) if they want a card or if they want to stay.
Dealer has to draw cards up until they hit 17 or better. If dealer has 17 or better dealer has to stay.
If player wins then you give him the money for his bet. If a tie, nothing happens. If dealer wins you
take the money.

15.5. Angle Relationships in Circles
First let's look at Angles Formed by Intersecting Chords (=Inside Angles).
Watch this video:
www.youtube.com/watch?v=WvG9Jz3jjSk
So as you can see in the video the two angles in the middle are vertical so they are always the same. And they are the average of the two arcs, in the video that means (78+50) multiplied by 0.5, which is 64 degrees.
Secondly, let's look at the Tangent Secant Exterior Angle Measure Theorem (=Outside Angles)
www.youtube.com/watch?v=eq1G7AWsTY8
So the (big arc - small arc) multiplied by 0.5 (or divided by 2 like in the video) = the outside angle.
Examples of the above:

Some thoughts :
(h,k) is like a coordinate point (x,y) but has to do with the middle point of a circle. If h=0, then (x-h)^2 becomes x^2. And the same if k=0, then (y-k)^2 becomes y^2.
What is h and k if you see this: (x-5)^2 and (y+7)^2 ? The easiest way to think about this is to just change the sign. So h=+5 and. y=-7.

Practice on Completing the Square. This is used for finding the equation of a circle in those cases when the equation is not in standard form.
You will also complete the square in Algebra 2 when you have a quadratic equation that is not factorable. For example: Solve x^2 + 6x - 11 = 0
In your notebook, copy the examples in the 3 links below.
Look at the second example for this one:
completing_square_0.jpg
Loom video of the above link:
www.loom.com/share/ec6c1c8663924fbfbbafa02e69e8dbd0
Look at the third example for this one:
completing_square_1.jpg
and finally this one:
completing_square_2.jpg
In the above examples you might have noticed that you take the coefficient in front of X and Y
and you divide it by 2. Then put a parenthesis and square it.
For example x^2-6x=12 would mean that you take -6/2 which is -3. Then you will have (-3)^2 which is 9. Add to both
left and right side of the equation.
Another example: y^2+3y=8 would mean that you take 3/2. Then you will have (3/2)^2 which is (9/4). Add to both
left and right side of the equation.
The reason you complete the square is that you want to be able to write it in standard form so that you can
figure out h,k and r for the circle equation. Once you have that you can graph the circle.

Classroom rules:
1. Park your phone on the whiteboard ledge within 10 seconds after entering the classroom.
IF YOU USE YOUR PHONE IN THE CLASSROOM YOU WILL SEE IT NEXT TIME AT 3.55 PM.
NO EXCEPTIONS. No head phones or ear buds.
Your phones will be retrieved when I tell you, about 3 minutes before the class ends,
row by row. After you get your phone, go back to your seat.
2. Sit in your assigned seat. Stay in your seat until bell the rings.
3. Computer and notebook up.
4. Look at the agenda. Do what the agenda says!
5. Do not pack up before I tell you to get your phone
(about 3 minutes before the end of class)
6. Be quiet from the bell rings until it is time for classwork (CW),
which usually takes place the last 30 minutes of the period.
TALKING DURING INSTRUCTION MEANS THAT YOU LOSE SOME
OF YOUR WEEKLY PARTICIPATION POINTS.
7. During classwork (CW) you can talk with a low volume
about math with your neighbors, but no LOUD talking/laughing.
8. No eating/drinking (except for water). No cursing.
9. DO NOT ASK TO GO TO THE RESTROOM DURING INSTRUCTION unless
it is an emergency. Do not go to the restroom often in my class.
Do not be gone for more than 5 minutes. Sign out, sign in when
you come back and remember to put the restroom pass back!
10. Do the CW and the homework (HW). If you do not do any CW
you will lose your weekly 100 participation points.
HW will be checked on a weekly or biweekly basis, but should be done every
day if you do not finish the CW/HW in class. If you procrastinate you will not have
time to finish your HW. You will get 100 or 200 points for the HW.
Since you can not use your phone, I recommend that you buy a calculator, TI 30 x is a great one because it is using solar cells.

Notes on Black Jack probabilities (105, top third only if short of time)
TIPS: Look at the dealers cards. If dealer has a lousy hand on the first card like 2-6,
then you should stay even if you have a low hand like 12-16. The reason is that the dealer
is running a high probability of going over 21.
However, if the dealer has a good first card like 7-11, then take a card if you have 12-16.
The reason is that dealer has a high chance of getting a 10 and will then have a better hand than you.
If you have 9,10 or 11 on your first two cards then you are allowed to "double down",
which means if your initial bet was $10, then you can now bet another $10.
You should do it if you have a better card than the dealer. For example you have 9, the dealer has 8.
TIPS IF YOU ARE THE DEALER:
Give one card face up to each player (going from left to right) and one to yourself.
Give a second card face up to each player and one to yourself BUT THIS ONE FACE DOWN.
Tell each player what the sum of their cards is and ask if they want another card.
Each player says (or shows) if they want a card or if they want to stay.
Dealer has to draw cards up until they hit 17 or better. If dealer has 17 or better dealer has to stay.
If player wins then you give him the money for his bet. If a tie, nothing happens. If dealer wins you
take the money.

15.5. Angle Relationships in Circles
First let's look at Angles Formed by Intersecting Chords (=Inside Angles).
Watch this video:
www.youtube.com/watch?v=WvG9Jz3jjSk
So as you can see in the video the two angles in the middle are vertical so they are always the same. And they are the average of the two arcs, in the video that means (78+50) multiplied by 0.5, which is 64 degrees.
Secondly, let's look at the Tangent Secant Exterior Angle Measure Theorem (=Outside Angles)
www.youtube.com/watch?v=eq1G7AWsTY8
So the (big arc - small arc) multiplied by 0.5 (or divided by 2 like in the video) = the outside angle.
Examples of the above:

Some thoughts :
(h,k) is like a coordinate point (x,y) but has to do with the middle point of a circle. If h=0, then (x-h)^2 becomes x^2. And the same if k=0, then (y-k)^2 becomes y^2.
What is h and k if you see this: (x-5)^2 and (y+7)^2 ? The easiest way to think about this is to just change the sign. So h=+5 and. y=-7.

Practice on Completing the Square. This is used for finding the equation of a circle in those cases when the equation is not in standard form.
You will also complete the square in Algebra 2 when you have a quadratic equation that is not factorable. For example: Solve x^2 + 6x - 11 = 0
In your notebook, copy the examples in the 3 links below.
Look at the second example for this one:
completing_square_0.jpg
Loom video of the above link:
www.loom.com/share/ec6c1c8663924fbfbbafa02e69e8dbd0
Look at the third example for this one:
completing_square_1.jpg
and finally this one:
completing_square_2.jpg
In the above examples you might have noticed that you take the coefficient in front of X and Y
and you divide it by 2. Then put a parenthesis and square it.
For example x^2-6x=12 would mean that you take -6/2 which is -3. Then you will have (-3)^2 which is 9. Add to both
left and right side of the equation.
Another example: y^2+3y=8 would mean that you take 3/2. Then you will have (3/2)^2 which is (9/4). Add to both
left and right side of the equation.
The reason you complete the square is that you want to be able to write it in standard form so that you can
figure out h,k and r for the circle equation. Once you have that you can graph the circle.
