I think the The answer 1/1 or1/2! If it is not correct then ask some one else
Answer:
x=-0.5
Step-by-step explanation:
the question is -9=18x
we divide both sides by 9
-1=2x
divide both sides by 2
x=-0.5
Answer:
.
Step-by-step explanation:
Two vectors
and
are parallel to one another if and only if the ratio between their corresponding components are equal:
.
Equivalently:
.
For the two vectors in this equation to be parallel to one another:
.
Solve for
:
.
would be the only valid value of
; no other value would satisfy the
equation.
Pi/12 radians = 180/12 degrees = 15 degrees
tan(15 degrees) = 0.2679... (rounded)
