Week 3 in Precalc 11

Tell:

This week we just started to learn “Absolute Value and Radicals”. One thing that I have learned so far is how to solve an equation that is given with negative numbers and the sum will be positive, when place inside |  |  Absolute value braces / symbols.

Show:

here is one equation that I was stuck on because I didn’t place the right signs besides the numbers, which was giving me the wrong answer.

Explain:

In this equation you plug in -3 where there is an x. The equation becoming -3^3 and -5(-3), getting results from those then solve the final equation. Equation will become a positive due to being inside the Absolute value braces.

 

Week 2 in Precalc 11

Tell:

This week I have learned how to determine a certain value for different geometric sequences, by using specific formulas created to find those results.

 

Show:

 

Explain:

In solving this problem you first need to find “R” by using the formula \frac{t_2}{t_1}. Once you have found “R”, you can determine t_1 by looking at the terms left to right. With all the information you have found now you can plug it all into the formula t_n = t_1 * R ^(n-1). Using BEDMAS go step by step to find your answer.
