Think About Others The Regents is coming up very soon. Talking makes it hard for everyone to learn. You cannot interrupt the mini- lesson…IT LOWERS the CLASSES REGENTS SCORE!!! (with less worktime and less effective lessons, how could it not)

The Mini-Lessons are very helpful to study

Think About Others• The Regents is coming up very soon.• Talking makes it hard for everyone
to learn.• You cannot interrupt the mini-
lesson…IT LOWERS the CLASSES REGENTS SCORE!!!
(with less worktime and less effective lessons, how could it not)
• They give us the formula. • We have to figure out where to put each
number in that formula
• V = Pert
P is the principal initially invested.
•What is the value of P?
•P = $1200
• V = Pert
• e is the base of a natural logarithm.
• The base of ln x (the natural logarithm) is e!!!
Here is where to find e^ on your calculator
•V = Pert
r is the rate of interest.
•What is the value of r?• The rate is 6.5%...REMEMBER!
Divide by 100 before using!!!6.5/100 = .065 r = .065
•V = Pert
t is for years
•What is t?
•10 years • t = 10
V = Pert
V = 1200 e^(.065*10)
V = 2298.648995…P = $1200e is er = .065t = 10
V 2298.65
• Be careful!!!
• This step is where the most mistakes are made.• Don’t forget the parenthesis!!!
2( x2 + 4x )
• If both bases are the same, then you know for a fact that the exponents have to be the same, too.
(if same, eliminate)
• Divide both sides by 2
• This is what is left when you divide by 2
• Add 3 to both sides
• Factor:(easy, 3 and 1 are only options)
• What makes the left side 0?-1 makes it 0-3 makes it 0.
• The solutions are:
We have gone over 80% of the Pre-Test problems during mini-lessons
• Your last Post-Test of the year will be on Friday.
• From this point on, we will have 2 small quizzes a week. This will test your knowledge of Trig and all the other outcomes we have done this year.
• You will turn in your Pre-Test with every problem done right before the Post-Test on Friday. If every problem is shown correctly, you will receive an E. (Remember, if you are stuck, solutions to these problems can be found online)
• Good luck on your final Post-Test!!!!
Today, we will meet in Responsibility Teams. Your Team is required to follow
UR rules while in your team.
1. If you have a question ask it.2. Make sure everyone in the
group is working!3. If everyone is stuck, work on it
together. If somebody knows, teach your group!!!
