Answer:
y = 0.5x
Step-by-step explanation:
Given that x and y vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 1, y = 0.5, then
k = 
= 
= 0.5, hence
y = 0.5x ← equation of variation
Answer: ~5
Step-by-step explanation:
It's been awhile for me but I think you do sin=opp/hyp
sin(45)=3sqrt(2)/x
x = 3sqrt(2)/sin(45) = (approx) 5
