Answer:
f(x) = 2/x and g(x) = 2/x
f(g(x)) = f(2/x) = 2/(2/x) = x
g(f(x)) = g(2/x) = 2/(2/x) = x
Answer:
308 cm³
Step-by-step explanation:
volume of cylinder = πr²h
volume = (22/7)*(7/2)*(7/2)*8
volume = 308cm³
20% of what is 36....
0.20x = 36
x = 36 / 0.20
x = 180 <== total price
In the given figure,
line a & b are parallel, line l and m are parallel.
for line a and b are parallel and line l act as a transversal.
So, angle BAC and ACD are the alterantive interior angles.
Angle BAC = Angle ACD
2x = 46
i.e. Angle BAC = 46
Lines l and m are parallel, a line act as a transversal,
So, the angle BAC and angle y are the corresponding angle,
Since the pair of corresponding angles are always equal so,
Angle BAC = y
46 = y
y = 46
Answer : y = 46
