Hey everyone, its a new week after parent teacher interviews .

I hope everything went well for every one.

Note* there is a math test on Wednesday on "Non-Linear Functions" apparently objectives 1-17

we didnt do mental math today because it was short blocks and we need to correct questions

we corrected the questions pg. A-7 10,11,12,13

Questions

10. for question 10 we used graphmatica typing in y=147x16x^2 and pressing enter we zoom in to see that 337.6 is the maximum hight,

then to trace the one second point you press point evaluate (on the menu at the top of the scaeen)

11. a)using graphmatica one again we type in y=4x/3-x^2/90 and enter

the maximum hight of the football is 40 feet

b)120ft

c)35yrds=(35x3)=105ft ...yes

d)35yrds(2.5feet)

*Trick* y=ten (it shows football and crossbar)

12. using excel spreadsheets we worked it out

total revenue ($)=(#of fares)($cost per ride)

letx=#of $1fare increases

lety=total revenue in $

y=(300-15x)(10+x)

after we figured eveerything out we put ot on a spread sheet

*You can also do this question the precalc way" by doing the let statements and doing the elimination method

13. Question 13 is quite similar to 12 you use the same methods

y=(4000-60x)(0.50+0.01x)

lety=$revenue total

x=no. of increases

We corrected excersise 2, #2(we used excell)

Other than the Harry Potter out burst haha, we also have a Practice test tomorrow just to review and go over a few things , ask questions and correct more questions

TEST DATE MOVED TO WED.

*~*make formula sheets and study study study Good Luck Class!!*~*
