Amanufacturing company has developed a cost model, c(x)= 0.15x^3 + 0.01x^2 +2x +120, where x is the number of item sold thousand. the sales price can be modeled by s(x) + 30- 0.01x. therefore revenues are modeled by r(x)= x*s(x). the company's profit, p(x) = r(x)-c(x) could be modeled by 1. 0.15x^3+ 0.02x^2- 28x+120 2. -0.15x^3-0.02x^2+28x-120 3. -0.15x^3+0.01x^2-2.01x-120 4. -0.15x^3+32x+120

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.

i need more info. are you looked to see there mph? how much they deliver? how far they go?
