Answer:
Step-by-step explanation:
THE TRICK HERE IS TO DISTRIBUTE THE MINUS SIGN TO THE SECOND TERM.
(6X+5)-(X-3)=
6X+5-X+3 (REMEMBER A NEGATIVE TIMES A NEGATIVE EQUALS A POSITIVE)
NOW COMBINE LIKE TERMS.
5X+8
Answer:
X-42.7
Y-5.34
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
cot(<em>θ</em>) = cos(<em>θ</em>)/sin(<em>θ</em>)
So if both cot(<em>θ</em>) and cos(<em>θ</em>) are negative, that means sin(<em>θ</em>) must be positive.
Recall that
cot²(<em>θ</em>) + 1 = csc²(<em>θ</em>) = 1/sin²(<em>θ</em>)
so that
sin²(<em>θ</em>) = 1/(cot²(<em>θ</em>) + 1)
sin(<em>θ</em>) = 1 / √(cot²(<em>θ</em>) + 1)
Plug in cot(<em>θ</em>) = -2 and solve for sin(<em>θ</em>) :
sin(<em>θ</em>) = 1 / √((-2)² + 1)
sin(<em>θ</em>) = 1/√(5)
Answer:
26.88
Step-by-step explanation:start eight times four is 32
and than eight times six is 48 than add a zero and do four times six is 24
and four times five is twenty add it up and line up the decimal points
hope i helped !!
