Answer:
13 1/3 and 6 2/3.
Step-by-step explanation:
Let the 2 parts be x and (20 - x).
So x^2(20 - x) must be a maximum.
y = x^2(20 - x)
y = 20x^2 - x^3
Finding the derivative):
y' = 40x - 3x^2 = 0 for maxm/minm value.
x( 40 - 3x) = 0
40 - 3x = 0
3x = 40
x = 40/3.
This is a maximum because the second derivative y" = 40 - 6x = 40 - 6(40/3)) is negative.
So the 2 numbers are 13 1/3 and 6 2/3.
Answer:
Step-by-step explanation:
There is theorem in this chapter which explains the answer
According to the theorem ,
/_rbd = 2 /_ rad
Therefore , rbd = 34 ° .
Hence , rad = 2x 34
Therefore , rad = 68°
What pair of fractions? I will be able to help i just need to know what fractions to use :)
(0,0) means the origin of the coordinate plane and its when bothe the x and y xoordinates are 0
