To calculate the tax rate...take the final price....divide by the "sticker" price.....then, subtract 1....finally......express the result as a percent....so we have.....
[101.28 / 96] - 1 =
1.055 -1 =
.055 =
5.5%
Yes......1034 / 100 = 10.34 = 1034%
This is a 2nd quad angle....hence the sine is positive....and since we have a 5-12-13 Pythagorean Triangle, the sine is just 5/13 ....so.....the cosine is -12/13
So.....
3sinΘ - 2cosΘ =
3(5/13) - 2(-12/13) =
15/13 + 24/13 =
39/13
Here you go.....
Uh.....65 years ???
I actually recall (kinda') that method from Linear Algebra........don't remember how to calculate that cross-product......maybe I'll go back and review it....
Hey.....I'm still working out how to write an equation of a line......!!!!
OK, Melody...got it.....
Don't ask me....I'm about to learn why 2 + 2 = 4....
I know this formula....but I don't see how you're getting this......can you "connect the dots" more fully for me??
Thanks
Melody....how did you obtain the fraction l 3x - 6 l / √13 as a perpendicular distance from R to PQ ????.....I'm not seeing how you got that
