 Question 165725: Hi, Can you help? . In my algebra book, It says that if the degree of the numerator is more than the denominator ( by more than one degree ), it does not have any horizontal asymptotes, is this true? . only has Vertical asymptotes of , and . would only have Vertical asymptotes . If the degrees are the same, the Horizontal asymptotes would be the leading coeffiecients, is this true? . would have Horizontal asymptotes of . If the degree of the numerator is smaller than the denominator, than the Horizontal asymptotes would always be , is this true? . , would have a Horizontal Asymtote of . If the numerator is only one degree more than the denominator, it doesn't have a Horizontal Asymptote, but it has an Oblique Asymptote (unless it is exactly divisible), is this true? . , would have an Oblique Asymptote of , (It has a remainder of . Am I correct with all these examples? ( I would appreciate it if I could have an answer as soon as possible ) . Thanks ahead of time,Levi Click here to see answer by MRperkins(300)

 Question 167480: I dont know how to work out this problem- You are stenciling wooden boxes to sell at a fair. It takes you 2 hours to stencil a small box and 3 hours to stencil a large box. You make a profit of \$10 for a small box, and \$20 for a large box. If you have no more than 30 hours available to stencil and want atleast 12 boxes to sell how many of each box should you stencil to maximize your profit ? a) Identify your variables. If x = small boxes, what does y=______ ? b) What is the objective function (profit) ? C=_____x+______y c)What are the constraints ? x+y_____12(boxes) _____x+_____y <_ _____hours d) Graph your constraints to find the feasible region. e) How many of each size box should you stencil to maximize your profit ?
