quick computing company produces calculators they have found that the cost c(x) of making x calculators is a quadratic function in terms of x. The company also discovered that it costs $45.00 to produce two calculators $143 to produce four calculators $143 to produce four calculators and $869 to produce ten calculators. Find the cost of producing seven calculators

Best ResponseYou've already chosen the best response.0First you know that this is a quadratic equation we all know to be old school nostalgia

Best ResponseYou've already chosen the best response.0Ok since now that you know this is a quadratic function you find the coordinates to find in with other coordinates in the form of quadratic equation which has parabola and vertex just like your teacher's lesson

Best ResponseYou've already chosen the best response.0you need to assume that this is a quadratic equation and that all of the coordinates described conform with the shape of that parabola old school

Best ResponseYou've already chosen the best response.0You can either use your calculator to do it, just assign it to quadratic equation and enter the coordinates given. Or you can draw it on a cartesian plane to get the approximate amount.

Best ResponseYou've already chosen the best response.0let c(x) = ax^2 + bx + c general form of a quadratic function from the data 45 = a(2)^2 + 2b + c 143 = a(4)^2+ 4b + c 869 = a(10^2 + 10b + c from this we can find values of a , b and c then plug in x = 7

Best ResponseYou've already chosen the best response.0so the system of equations is 4a + 2b + c = 45 16a + 4b + c = 143 100a + 10b + c = 869

Best ResponseYou've already chosen the best response.0if you subtract the first one from the second then 2nd from the third you will eliminate the c and get 2 equations in a and b

Best ResponseYou've already chosen the best response.012a + 2b = 98 84a + 6b = 726

Best ResponseYou've already chosen the best response.0now multiply first equation by 3 and add 36a  6b = 294 84a + 6b = 726 adding: 48a = 432 a = 432/48 = 9 a = 9
