For each function, y varies directly with x. Find each constant variation. Then find the value of y when x= -0.3.
prohojiy [21]
You meant "find the constant of proportionality"

Given <span>y=2 when x= -1/2, and looking for a formula such as y = k*x, 
substitute the given value (2) for y and the given value (-1/2) for x:

2 = k * (-1/2).  Solve this for k.      Then write out the general formula y = k * x, and let x= -0.3.</span>

In a right angled triangle :

Ratio of the leg Adjacent an angle to the hypotenus can be obtained using the Cosine trigonometric ratio

For an angle of 23° and and adjacent leg of 46

Cos 23 = adjacent / hypotenus

Adjacent / hypotenus = 0.92

46 / hypotenus = 0.92

Hypotenus = 46 / 0.92

Hypotenus = 50
