Answer:
2) 0.3
4) 0.09
6) 0.65
8) 4.45
Step-by-step explanation:
hope this helps ;)
1) Factor out common terms in the first two terms, then in the last two terms
{x}^{3}(x+2)-2(x+2)
2) Factor out the common term x+2
(x+2)({x}^{3}-2)
Done!
If sinα=1/4 and it is in q2 it means that the x coordinate is negative.
The triangle has a height of one and a hypotenuse of 4 so:
x=-√(4^2-1)
x=-√15
so tanα=-1/√15
tanα=-√(1/15)
tanα≈ -0.258
18k i believe because it is a varible and a number so when u multiply them u just put them together.... is this multi choice question because to see the answers would help
