A company finds that if it Charges x dollars for a cell phone, it can expect to cell 1,000-2x phones. The company uses the function r defined by r(x) = x (1000 - 2x) to model the expected revenue, in dollars, from selling cell phones at xdollars each. Use graphing technology to graph the function r. What do the x intercept means in this situation? Is 0 < x < 600 an appropriate domain for the function r? At what price should the company sell their phones to get the maximum revenue? Explain your reasoning.​

step-by-step explanation:

i just know the internet

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
