no way dude really? thats so cool
Answer:
x = 10 cm, y = 5 cm gives a minimum area of 300 cm^2.
Step-by-step explanation:
V= x^2y = 500
Surface area A = x^2 + 4xy.
From the first equation y = 500/x^2
So substituting for y in the equation for the surface area:
A = x^2 + 4x * 500/x^2
A = x^2 + 2000/x
Finding the derivative:
dA/dx = 2x - 2000x^-2
dA/dx = 2x - 2000/x^2
This = 0 for a minimum/maximum value of A, so
2x - 2000/x^2 = 0
2x^3 - 2000 = 0
x^3 = 2000/ 2 = 1000
x = 10
Second derivative is 2 + 4000/x^3
when x = 10 this is positive so x = 10 gives a minimum value of A.
So y = 500/x^2
= 500/100
= 5.
Its already in simplest form u cant simplify it hope this helps!!
If LFX=AZQ, then XFL=QZA & FXL=ZQA
Answer:
slope line 1: -2
slope line 2: -2
slope line 3: 2
line 1 &2: parallel
line 1&3: perpendicular
line 2&3: perpendicular
Step-by-step explanation:
Slope formula: y2-y1/x2-x1
line 1) 2--2/0-2= -2
line 2) -5--1/1--1=-2
line 3) 0--4/-3--5=2
