Suppose we want to build a rectangular storage container with open top whose volume is $$12 cubic meters. Assume that the cost o

Snezhnost [94]

Answer:265.25

Step-by-step explanation:

Given

Volume of box $=12 m^3$

height is 3 times the width

let height, length and breadth be H, L & B

$H=3\times B$

$V=12=L\times B\times H$

4=B^2\times L[/tex]

$L=\frac{4}{B^2}$

Cost of side walls $ $8/m^2$

Cost of base $ $12/m^2$

Cost of side walls $=(2LH+2BH)\cdot 8$

Cost of base $=12LB$

Total cost $C=16LH+16BH+12LB$

$C=48LB+48B^2+12LB$

$C=\frac{192}{B}+48B^2+\frac{48}{B}$

differentiate C w.r.t B to get minimum cost

$\frac{\mathrm{d} C}{\mathrm{d} B}=-\frac{192}{B^2}+2\times 48 B-\frac{48}{B^2}$

$B^3=\frac{240}{2\times 48}$

$B=1.35 m$

$H=3\times 1.35=4.07 m$

L=2.19 m

C=$ 265.25

1. Which is equivalent to the expression below?<br> (3.x2 – 2x + 5) - (2x2 – 5x + 1)

Nana76 [90]

Answer:

x = 6

x = 1

Step-by-step explanation:

(3x² - 2x + 5) - (2x² - 5x + 1)

= 3x² - 2x² - 2x - 5x + 5 + 1

= x² - 7x + 6

= (x - 6)(x - 1)

x - 6 = 0

x = 6

x - 1 = 0

x = 1

Tyler planted potatoes, oats, and corn. There were 23 acres planted with potatoes. There were three times as many acres planted

valentina_108 [34]

You just have to multiply 23 * 3 = 69. So there were 23 acres of potatoes and 69 acres of corn and oats. 69 + 23 = 92. Your answer is 92 acres total.
