<span>B) A key chain can hold 3 keys. If there are a total of 12 keys, how many key chains are there?</span>
Answer:
d
a
Step-by-step explanation:
f(3)= 3(3)-1
f(3)=9-1=8
f(x+1)= (x+1)^2-3(x+1)+2
=x^2+2x+1-3x-3+2
=x^2-x
Now, the cosecant of θ is -6, or namely -6/1.
however, the cosecant is really the hypotenuse/opposite, but the hypotenuse is never negative, since is just a distance unit from the center of the circle, so in the fraction -6/1, the negative must be the 1, or 6/-1 then.
we know the cosine is positive, and we know the opposite side is -1, or negative, the only happens in the IV quadrant, so θ is in the IV quadrant, now

recall that

therefore, let's just plug that on the remaining ones,

now, let's rationalize the denominator on tangent and secant,
6 1/10
Step-by-step explanation:
4 + 1/2+1+3/5
5+1+1/10=6 1/10
