What expression represents the profit, and what is the profit if 240 cell phones are sold?
Profit is the difference between revenue and cost. The
revenue, in dollars, of a company that manufactures
cell phones can be modeled by the polynomial 2x2 +
55x + 10. The cost, in dollars, of producing the cell
phones can be modeled by 2x2 - 15x - 40. The
variable x represents the number of cell phones sold.
O40x - 30; $2,400
040x - 30; $9,570
O 70x + 50; $16, 850
O 70x + 50; $28,800

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

(picture explains)

this is a good question! i'll do some research and come back when i have the answer!

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3

option b  

step-by-step explanation:

we know that

the distance from point n to lm in the figure is equal to the distance of the perpendicular line to lm that passes through the point n

so

the distance is equal to the segment no

> given problem

therefore

the distance from point n to lm is equal to
