Answer:
<em>2.5</em>
Step-by-step explanation:
A direct variation equation has the form y = kx, where k is the constant of proportionality.
In this case, the constant of proportionality is 2.5.
False because, you DO add 4 to the sides but you would multiply the 8 because you to the opposite to cancel it out
csc(2x) = csc(x)/(2cos(x))
1/(sin(2x)) = csc(x)/(2cos(x))
1/(2*sin(x)*cos(x)) = csc(x)/(2cos(x))
(1/sin(x))*1/(2*cos(x)) = csc(x)/(2cos(x))
csc(x)*1/(2*cos(x)) = csc(x)/(2cos(x))
csc(x)/(2*cos(x)) = csc(x)/(2cos(x))
The identity is confirmed. Notice how I only altered the left hand side (LHS) keeping the right hand side (RHS) the same each time.
