A horizontal beam safely supports a load P that varies jointly as… A horizontal beam safely supports a load P that varies jointly as the product of the width W of the beam and the square of the depth D and inversely as the length L. A beam that has a width of6 in, depth of 24 ​in, and length of12 in can safely support3,744lb. Determine the safe load in pounds of a beam made from the same material if the beam is 36 in long. content area bottomPart 1The safe load is____pounds? 2. The number of items sold varies directly with the discount given. If 323 items are sold when there is a​ 30% discount, how many items would you expect to sell if there is a 50​% discount​ given?_____items. 3.Use a variation equation to solve. An electronics manufacturer determines that the demand for its portable radio is directly proportional to the amount spent on advertising and inversely proportion to the price of the radio.  Let d​ = demand, k​ = the constant of​ proportionality, a​ = advertising money and p​ = price A. d​ = kp/a  B. d​ = kap C k​ = d/ap D. d​ = ka/pWhen ​$20,000 is spendt on advertising and the price is​ $20, the monthly demand is​ 10,000 radios. Find the value of​ k, the proportionality constant for this situation. k​ =_______?​(Round to a whole​ number)Use the rounded value of k. What will be the demand if the price is raised to​ $25? The money spent on advertising remains the same. ______radios          Math Algebra MATH 150 Share (0)
