Answer:
(1/2, 6).
Step-by-step explanation:
Turning points in a graph may exist whenever the derivative equals 0. Hence, let’s differentiate and then solve our function.
We have:

Take the derivative of both sides with respect to x:

Simplify:

We will now set this equal to 0 and solve for x. Hence:

Hence, the graph turns at x=1/2. This is the x-coordinate.
Then it follows that the y-coordinate will be:

Hence, our coordinate Is (1/2, 6).
Answer:
x = 3
Step-by-step explanation:
take 60 degree as reference angle and using cos rule
cos 60 = adjacent/hypotenuse
1/2 = x/6
do cross multiplication
2*x = 6*1
x = 6/2
x = 3
