Best ResponseYou've already chosen the best response.1is there any restriction on value of s ?

Best ResponseYou've already chosen the best response.0First I found P(0) which equals (0, 1077). Then I found P(s) which equals (15.45, 0)

Best ResponseYou've already chosen the best response.0Those are the two points. Now I have to graph it and then find the domain and range.

Best ResponseYou've already chosen the best response.2in order to make profit domain should be [16, max no of radio available] correspondingly you can find range.

hiralpatel121

Best ResponseYou've already chosen the best response.0Wouldn't the domain be [0,1077]?

pradipgr817

Best ResponseYou've already chosen the best response.2lets say total no. of radio is a your function is P(s)=69.70s1077 values of s is the domain at s=15.45 break even point occurs so at this point P(s)=0 But radio quantity is in integer so s=16. Nowo if he sells more than this only he will get profit i.e., [16 a] at 16 P(s)=0 and at s=a, P(a), so range is [P(16) P(a)]=[0 P(a)]

Best ResponseYou've already chosen the best response.0So would range be [0, 15.45]?

pradipgr817

Best ResponseYou've already chosen the best response.2lets solve together. you start I'll correct you

hiralpatel121

Best ResponseYou've already chosen the best response.0I have already solved it earlier. [0, 1077] and [15.45, 0]

hiralpatel121

Best ResponseYou've already chosen the best response.0Now the directions say to graph these points and then determine the domain and range.

pradipgr817

Best ResponseYou've already chosen the best response.2in that answer is correct your domain is (0 infinity) [all possibilities included]

hiralpatel121

Best ResponseYou've already chosen the best response.0So what's the range?

hiralpatel121
 3 years ago
Best ResponseYou've already chosen the best response.0Okay so Domain is [0, infinity) and Range is [1077, infinity). Correct?

hiralpatel121

Best ResponseYou've already chosen the best response.0Why wouldn't the domain be [0, 15.45]?

pradipgr817

Best ResponseYou've already chosen the best response.2first of all no. of radio cannot be 15.45

hiralpatel121

Best ResponseYou've already chosen the best response.0Nevermind, I got it. Can you help me with one more problem?

pradipgr817

Best ResponseYou've already chosen the best response.2second during this part only loss will occur. what about the profits? it will occur after your 15.45 so extend your range. finally max. no. of radio are not given so infinite number can exist. therefore domain is [0 infinity), not below zero as number of radio cannot be negative

Best ResponseYou've already chosen the best response.2you put the values of x and y in equation and solve it. I haven't solved it. To check you got it right put the know value and check the answer

pradipgr817

Best ResponseYou've already chosen the best response.2Initially in 2000, the income was 39.3 (your intercept). This per capita income increases unifomly, whose rate is given by the slope of the curve, which is 0.8.

pradipgr817

Best ResponseYou've already chosen the best response.2and as the time will progress the per capita income will increase only. as per the equation, with increase in time it cannot decrease.

pradipgr817

Best ResponseYou've already chosen the best response.2see, t is years sine 2000. So subtract 2000 from years. You have 5, 7...11 as x. and ticket cost is y
