you have to use intercept theorem, also known as Thales's theorem to slove this problem
Answer:
x = 0
Step-by-step explanation:
To get the extrema, derive the function.
You get y' = 2x^-1/3 - 2.
Set this equal to zero, and you get x=0 as the location of a critical point.
Since you are on a closed interval [-1, 1], those points can also have an extrema.
Your min is right, but the max isn't at (1,1). At x=-1, you get y=5 (y = 3(-1)^2/3 -2(-1); (-1)^2/3 = 1, not -1).
Thus, the maximum is at (-1, 5).
Ill answer it for you 150 cubic meters
9(3+5) is equivalent because factoring a 9 out of both 27 and 45 leaves us with 9(3+5).
