that's smarter
OpenStudy (anonymous):
thanks haha
OpenStudy (anonymous):
they tell you what to do here
the maximum is 0, the minimum is \(-4\) for a total length of \(4\)
and half of \(4\) is ?
OpenStudy (anonymous):
2! so it would be 4:2
OpenStudy (anonymous):
yes
i don't see that choice, but yes

Just type the number in on a calculator and hit the cos button or the sin button

Your answer will come out in decimal form so you have to convert it into a fraction and see which one is your answer
OpenStudy (anonymous):
Cos 105=-0.2588
Sin 150=0.50
Change them into decimals and you have your answer
OpenStudy (anonymous):
Change them into fractions and you have your answer
OpenStudy (anonymous):
so would it be A?
OpenStudy (ipwnbunnies):
No, it won't. Night Watcher used cos(105) instead of cos(150).
Do you know certain special triangles, and terminal angles?

Or you can plug these numbers into a calculator. o.o
OpenStudy (anonymous):
how would I do that
OpenStudy (ipwnbunnies):
Do which?
OpenStudy (anonymous):
into the calculator
OpenStudy (ipwnbunnies):
Nightwatcher told you. o.o
Press the COS key, put 150 in the parentheses. Enter.

is -0.8 right
OpenStudy (ipwnbunnies):
Mhm, do the same the SIN(150). Then figure out which choice matches your numbers.
OpenStudy (anonymous):
its 0.5
