A box with a square base and no top is to be built with a volume of 4000 in3. find the dimensions of the box that requires the l

vekshin1

Let the length of the square base be x inches .

And the height of the box be y inch .

Volume = x*x*y

4000 = x *x *y

$y = \frac{4000}{x^2}$

S = x*x + 2xy + 2 x y

$S = x^2 + 4 xy$

$S = x^2+ 4x* \frac{4000}{x^2}$

$S = x^2 + \frac{16000}{x}$

$S ' = 2x - \frac{16000}{x^2}$

S ' =0

$2x - \frac{16000}{x^2}=0$

$2x^3 - 16000 = 0$

$x^3 = 8000$

x = 20

$y = \frac{4000}{20^2} = \frac{4000}{400} = 10$

A landscaping company placed three orders with a nursery. The first order was for bushes, trees, and bundles of flowers, and tot

notsponge [240]

To add the bushes and trees, to get 19 bushes and 6 trees, but this wouldn't get me anywhere, because I don't have subtotals for the bushes and trees.

So I'll pick variables (b for the number of bushes and t for the number of trees) and set up a system of equations:

first order: 13b + 4t = 487

second order: 6b + 2t = 232

Multiplying the second row by –2, I get:

13b + 4t = 487

–12b – 4t = –464

This says that b = 23.

Back-solving, I get that t = 47.

Of course, the exercise didn't ask for the values of the two variables. Translating back into English, the solution is,

each bush is $23 and each tree is $47.
