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).
The new volume is Nine time the original volume
Step-by-step explanation:
Let the length be 'l'
Let the height be 'h'
Let the width be 'w'
Volume of a rectangular prism= l x w x h
New length = 1.5l
New width = 2w
New height= 3h
New volume= (1.5l) x (2w) x (3h)
= 9 (l x w x h)
New volume= 9 ( original volume)
The new volume is 9 time the original volume
1/3x7/8 is the answer give me a thank plz
Increasing the sample size by a factor of 4 or multiplying
it by 4 is equal to increasing the standard error by 1/2. Therefore, the
interval will be half as varied. This also works almost for population
averages as lengthy as the multiplier from the t-curve doesn't modify much when
increasing the sample size.
