Step-by-step explanation:
Answer:
4d+2m+13
Step-by-step explanation:
<span>The area of the base is x^2> The height is h. Each side of the box has area xh. There are 4 sides of the box so the total surface area of the box is x^2+4xh and that is equal to 1000. Solve that equation for h:
x^2+4xh = 1000 h = (1000-x^2)/4x so the Volume = x^2[(1000-x^2)/4x]
Simplify and get V = 250x-x^3/4
The volume will be a maximum when its first derivative is 0.
V' = 250-3/4x^2
Set to 0 and solve. x=18.26
Now plug into the volume function to find the maximum volume:
V=250(18.26)-(18.26)^3/4
V= 4564.35 - 1522.10 =3042.25</span>
Answer:
41/4 remainder is 1
Step-by-step explanation:
10 is the answer
Answer: C 2x(x - 2) - x = 0
and <u>B</u> 2x² – 5x=0
Step-by-step explanation:
You get 2x(x - 2) - x = 0 by subtracting x from both sides of the original equation.
Then take 2x(x - 2) - x = 0 and distribute to get 2x² - 4x -x = 0
combine the x terma and you end up with 2x² – 5x=0
