Week Five

Algebra 2H pd 1
We learned more the irrational number e today. We graphed y=e^x in our notes and graphing calculators. We also learned the formula for compounding interest continuously. A=Pe^rt.
HW Worksheet # 1-9 all and #13-19 all
EC Problem...How much more money would you make if you deposited $5000 at 5% interest compounded continuously for 10 years vs $5000 at 5% interest compounded monthly for 10 years? Use A=P(1+r/n)^nt for the monthly calculation.

Geometry H pds 2,4
We went over the Converse of the Pythagorean Theorem today. This states that if c^2 = a^2 + b^2, then the triangle is a right triangle. We also learned how to tell if a triangle can be formed, and how to tell if the triangle is acute or obtuse.
HW Worksheet # 1-16 all
EC problem....Write 10 Pythagorean Triples that were NOT given in today's notes. Try to use the shortcut method I told you about in class.

Algebra 2B pd 5
We went over ALL log and exponential equations during class. Hopefully, everyone knows how to solve them!
HW 3 problems:
1) 5x^3/7 = 120

2) 3^4x = 8^(x-3)

3) the cubed root of 3^2x+8 = 5^x

EC problems....Solve 2^(5x-1) = 3^(2x+1)
