Well, he said I could use every resource I have lol

Answer 3

ah well that is alright :D

Answer 4

could you help me?

Answer 5

nope sorry @mathstudent55

Answer 6

if you take the derivative then set the equation to = 0 then solve you will have a max or min \[\frac{d}{dx} 100x^2-1700x = 200x-1700\]now we need to set F(x) to zero then solve for x \[200x - 1700=0\]\[200x = 1700\]\[x = \frac{1700}{200}\]

Answer 7

in our case since we are positive we have a min

Answer 8

and also if you graph the function you can see the min
