A box with a volume of 8 m3 is to be constructed with a gold-plated top, silver-plated bottom, and copper-plated sides. If gold plate costs $130 per square meter, silver plate costs $30 per square meter, and copper plate costs $10 per square meter, find the dimensions that will minimize the cost of the materials for box.

step-by-step explanation:

can you add an image ?

step-by-step explanation:

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

ummm seems that u didnt post the attachement !
